Uni-Seal small diameter details
Uni-Seal is a spring actuated and pressure assisted sealing device consisting of a PTFE jacket and a corrosion resistantmetal spring energiser When the Uni-Seal is seated in the gland the spring is under compression forcing the jacket against the hardware The spring compensates for jacket wear and eccentricity The system pressure assists the spring pressure The spring load can be tailored to meet special low friction requirements in dynamic applications and loading can be increased for cryogenic sealing

Maximum recommended diametral extrusion gap
When sealing high pressure andor temperature the clearance between the hardware ldquoExtrusion gaprdquo becomes very important At high pressure and or temperature the jacket material can extrude into the gap causing premature sealing failure The extrusion gap should be held to the minimum practical or should not exceed above values Back-up rings are manufactured of a harder material than the seal material

Surface finishes and hardness
DynamicThe quality of the surface finish influences the relative wearof the cover material The transfer of a thin film of PTFE from the seal cover to the mating dynamic surface will improve seal life Relatively rough finishes wear the cover material too rapidly whereas too smooth surfaces result in insufficient material transfer to form a thin film As general rule the higher the sealing surface hardness the better the seal performance Higher hardness reduces wear and increases seal life A 40 HRC or higher is recommended for slow to moderate movements
StaticEnsure that the seals counterfaces are free from scores and spiral machining marks

Solid back-up rings and O rings
Back-up rings are used in combination with axial and radial seals when the extrusion gap is too big for the required pressure and temperature
O rings made of PTFE are used in all applications in which the chemical resistance of conventional elastomer O rings is not adequate PTFE O rings can only be used as static seals PTFE lsquoOrsquo rings are manufactured by machining and can be produced in all sizes

Wear rings are designed to guide piston and the piston rods of power cylinders and to absorb the lateral forces which occur They also prevent metal to metal contact between sliding parts Wear rings are available in tape or machined rings
An important advantage is that metallic seizure cannot occur with the correct design The most frequently used non-metallic wear ring materials are filled PTFE and compounds of PTFE and fabric materials
Wear rings are fitted easily into closed grooves on the piston or in the gland The number of wear rings to be used will depend on the radial forces and the permissible surface pressure of the wear ring material in addition to the length of stroke the diameter and other design factors
Advantagebull Very good anti-friction behaviourbull No stick-slip effectbull Good dry running characteristicsbull Good wear resistance with long service life

The wear rings can be used in all hydraulic oil media
PTFE materials have a low coefficient of friction but also low load caracteristics They are therefore better used for low load applications
Thermoplastic materials have a higher friction coefficient but also high load characteristics and can be used in high pressure applications
Cuts
Wear rings are made with different cuts
X- Cut For reciprocating movement
Y- Cut For rotary movement
Z- Cut For reciprocating or rotary movements in contaminated systems to protect the seal
In extremely contaminated systems consideration should be given to the use of Code 07 material in-board of one of our seals with other wear ring materials in the out-board position

Uni-Seal small diameter details
Uni-Seal is a spring actuated and pressure assisted sealing device consisting of a PTFE jacket and a corrosion resistantmetal spring energiser When the Uni-Seal is seated in the gland the spring is under compression forcing the jacket against the hardware The spring compensates for jacket wear and eccentricity The system pressure assists the spring pressure The spring load can be tailored to meet special low friction requirements in dynamic applications and loading can be increased for cryogenic sealing

Maximum recommended diametral extrusion gap
When sealing high pressure andor temperature the clearance between the hardware ldquoExtrusion gaprdquo becomes very important At high pressure and or temperature the jacket material can extrude into the gap causing premature sealing failure The extrusion gap should be held to the minimum practical or should not exceed above values Back-up rings are manufactured of a harder material than the seal material

Surface finishes and hardness
DynamicThe quality of the surface finish influences the relative wearof the cover material The transfer of a thin film of PTFE from the seal cover to the mating dynamic surface will improve seal life Relatively rough finishes wear the cover material too rapidly whereas too smooth surfaces result in insufficient material transfer to form a thin film As general rule the higher the sealing surface hardness the better the seal performance Higher hardness reduces wear and increases seal life A 40 HRC or higher is recommended for slow to moderate movements
StaticEnsure that the seals counterfaces are free from scores and spiral machining marks

Uni-Seal mdash J40 - J42
Standard profiles Types J40 J41 and J42RADIAL SEALS
Type
J40
Type J40 utilises a wrapped and formed ribbon spring The design offers the utmost in spring deflection for otherwise difficult sealing applications Can be used for reciprocating and slow rotary motion in dynamic and static sealing Type 41 as Type J40 plus extended heel for high pressures
Type
J41
J42As Type 40 Due to the clamping of the flange the seal will be prevented from turning with the shaft This can occur with standard designs due to thermal and other effects with dynamic applications
Hardware dimensions as per pages 7 or 9

Solid back-up rings and O rings
Back-up rings are used in combination with axial and radial seals when the extrusion gap is too big for the required pressure and temperature
O rings made of PTFE are used in all applications in which the chemical resistance of conventional elastomer O rings is not adequate PTFE O rings can only be used as static seals PTFE lsquoOrsquo rings are manufactured by machining and can be produced in all sizes

Wear rings are designed to guide piston and the piston rods of power cylinders and to absorb the lateral forces which occur They also prevent metal to metal contact between sliding parts Wear rings are available in tape or machined rings
An important advantage is that metallic seizure cannot occur with the correct design The most frequently used non-metallic wear ring materials are filled PTFE and compounds of PTFE and fabric materials
Wear rings are fitted easily into closed grooves on the piston or in the gland The number of wear rings to be used will depend on the radial forces and the permissible surface pressure of the wear ring material in addition to the length of stroke the diameter and other design factors
Advantagebull Very good anti-friction behaviourbull No stick-slip effectbull Good dry running characteristicsbull Good wear resistance with long service life

The wear rings can be used in all hydraulic oil media
PTFE materials have a low coefficient of friction but also low load caracteristics They are therefore better used for low load applications
Thermoplastic materials have a higher friction coefficient but also high load characteristics and can be used in high pressure applications
Cuts
Wear rings are made with different cuts
X- Cut For reciprocating movement
Y- Cut For rotary movement
Z- Cut For reciprocating or rotary movements in contaminated systems to protect the seal
In extremely contaminated systems consideration should be given to the use of Code 07 material in-board of one of our seals with other wear ring materials in the out-board position

Uni-Seal small diameter details
Uni-Seal is a spring actuated and pressure assisted sealing device consisting of a PTFE jacket and a corrosion resistantmetal spring energiser When the Uni-Seal is seated in the gland the spring is under compression forcing the jacket against the hardware The spring compensates for jacket wear and eccentricity The system pressure assists the spring pressure The spring load can be tailored to meet special low friction requirements in dynamic applications and loading can be increased for cryogenic sealing

Maximum recommended diametral extrusion gap
When sealing high pressure andor temperature the clearance between the hardware ldquoExtrusion gaprdquo becomes very important At high pressure and or temperature the jacket material can extrude into the gap causing premature sealing failure The extrusion gap should be held to the minimum practical or should not exceed above values Back-up rings are manufactured of a harder material than the seal material

Surface finishes and hardness
DynamicThe quality of the surface finish influences the relative wearof the cover material The transfer of a thin film of PTFE from the seal cover to the mating dynamic surface will improve seal life Relatively rough finishes wear the cover material too rapidly whereas too smooth surfaces result in insufficient material transfer to form a thin film As general rule the higher the sealing surface hardness the better the seal performance Higher hardness reduces wear and increases seal life A 40 HRC or higher is recommended for slow to moderate movements
StaticEnsure that the seals counterfaces are free from scores and spiral machining marks

Solid back-up rings and O rings
Back-up rings are used in combination with axial and radial seals when the extrusion gap is too big for the required pressure and temperature
O rings made of PTFE are used in all applications in which the chemical resistance of conventional elastomer O rings is not adequate PTFE O rings can only be used as static seals PTFE lsquoOrsquo rings are manufactured by machining and can be produced in all sizes

Wear rings are designed to guide piston and the piston rods of power cylinders and to absorb the lateral forces which occur They also prevent metal to metal contact between sliding parts Wear rings are available in tape or machined rings
An important advantage is that metallic seizure cannot occur with the correct design The most frequently used non-metallic wear ring materials are filled PTFE and compounds of PTFE and fabric materials
Wear rings are fitted easily into closed grooves on the piston or in the gland The number of wear rings to be used will depend on the radial forces and the permissible surface pressure of the wear ring material in addition to the length of stroke the diameter and other design factors
Advantagebull Very good anti-friction behaviourbull No stick-slip effectbull Good dry running characteristicsbull Good wear resistance with long service life

The wear rings can be used in all hydraulic oil media
PTFE materials have a low coefficient of friction but also low load caracteristics They are therefore better used for low load applications
Thermoplastic materials have a higher friction coefficient but also high load characteristics and can be used in high pressure applications
Cuts
Wear rings are made with different cuts
X- Cut For reciprocating movement
Y- Cut For rotary movement
Z- Cut For reciprocating or rotary movements in contaminated systems to protect the seal
In extremely contaminated systems consideration should be given to the use of Code 07 material in-board of one of our seals with other wear ring materials in the out-board position

Uni-Seal small diameter details
Uni-Seal is a spring actuated and pressure assisted sealing device consisting of a PTFE jacket and a corrosion resistantmetal spring energiser When the Uni-Seal is seated in the gland the spring is under compression forcing the jacket against the hardware The spring compensates for jacket wear and eccentricity The system pressure assists the spring pressure The spring load can be tailored to meet special low friction requirements in dynamic applications and loading can be increased for cryogenic sealing

Maximum recommended diametral extrusion gap
When sealing high pressure andor temperature the clearance between the hardware ldquoExtrusion gaprdquo becomes very important At high pressure and or temperature the jacket material can extrude into the gap causing premature sealing failure The extrusion gap should be held to the minimum practical or should not exceed above values Back-up rings are manufactured of a harder material than the seal material

Surface finishes and hardness
DynamicThe quality of the surface finish influences the relative wearof the cover material The transfer of a thin film of PTFE from the seal cover to the mating dynamic surface will improve seal life Relatively rough finishes wear the cover material too rapidly whereas too smooth surfaces result in insufficient material transfer to form a thin film As general rule the higher the sealing surface hardness the better the seal performance Higher hardness reduces wear and increases seal life A 40 HRC or higher is recommended for slow to moderate movements
StaticEnsure that the seals counterfaces are free from scores and spiral machining marks

Wear rings are designed to guide piston and the piston rods of power cylinders and to absorb the lateral forces which occur They also prevent metal to metal contact between sliding parts Wear rings are available in tape or machined rings
An important advantage is that metallic seizure cannot occur with the correct design The most frequently used non-metallic wear ring materials are filled PTFE and compounds of PTFE and fabric materials
Wear rings are fitted easily into closed grooves on the piston or in the gland The number of wear rings to be used will depend on the radial forces and the permissible surface pressure of the wear ring material in addition to the length of stroke the diameter and other design factors
Advantagebull Very good anti-friction behaviourbull No stick-slip effectbull Good dry running characteristicsbull Good wear resistance with long service life

The wear rings can be used in all hydraulic oil media
PTFE materials have a low coefficient of friction but also low load caracteristics They are therefore better used for low load applications
Thermoplastic materials have a higher friction coefficient but also high load characteristics and can be used in high pressure applications
Cuts
Wear rings are made with different cuts
X- Cut For reciprocating movement
Y- Cut For rotary movement
Z- Cut For reciprocating or rotary movements in contaminated systems to protect the seal
In extremely contaminated systems consideration should be given to the use of Code 07 material in-board of one of our seals with other wear ring materials in the out-board position

Maximum recommended diametral extrusion gap
When sealing high pressure andor temperature the clearance between the hardware ldquoExtrusion gaprdquo becomes very important At high pressure and or temperature the jacket material can extrude into the gap causing premature sealing failure The extrusion gap should be held to the minimum practical or should not exceed above values Back-up rings are manufactured of a harder material than the seal material

Surface finishes and hardness
DynamicThe quality of the surface finish influences the relative wearof the cover material The transfer of a thin film of PTFE from the seal cover to the mating dynamic surface will improve seal life Relatively rough finishes wear the cover material too rapidly whereas too smooth surfaces result in insufficient material transfer to form a thin film As general rule the higher the sealing surface hardness the better the seal performance Higher hardness reduces wear and increases seal life A 40 HRC or higher is recommended for slow to moderate movements
StaticEnsure that the seals counterfaces are free from scores and spiral machining marks

Wear rings are designed to guide piston and the piston rods of power cylinders and to absorb the lateral forces which occur They also prevent metal to metal contact between sliding parts Wear rings are available in tape or machined rings
An important advantage is that metallic seizure cannot occur with the correct design The most frequently used non-metallic wear ring materials are filled PTFE and compounds of PTFE and fabric materials
Wear rings are fitted easily into closed grooves on the piston or in the gland The number of wear rings to be used will depend on the radial forces and the permissible surface pressure of the wear ring material in addition to the length of stroke the diameter and other design factors
Advantagebull Very good anti-friction behaviourbull No stick-slip effectbull Good dry running characteristicsbull Good wear resistance with long service life

The wear rings can be used in all hydraulic oil media
PTFE materials have a low coefficient of friction but also low load caracteristics They are therefore better used for low load applications
Thermoplastic materials have a higher friction coefficient but also high load characteristics and can be used in high pressure applications
Cuts
Wear rings are made with different cuts
X- Cut For reciprocating movement
Y- Cut For rotary movement
Z- Cut For reciprocating or rotary movements in contaminated systems to protect the seal
In extremely contaminated systems consideration should be given to the use of Code 07 material in-board of one of our seals with other wear ring materials in the out-board position

Solid back-up rings and O rings
Back-up rings are used in combination with axial and radial seals when the extrusion gap is too big for the required pressure and temperature
O rings made of PTFE are used in all applications in which the chemical resistance of conventional elastomer O rings is not adequate PTFE O rings can only be used as static seals PTFE lsquoOrsquo rings are manufactured by machining and can be produced in all sizes

Wear rings are designed to guide piston and the piston rods of power cylinders and to absorb the lateral forces which occur They also prevent metal to metal contact between sliding parts Wear rings are available in tape or machined rings
An important advantage is that metallic seizure cannot occur with the correct design The most frequently used non-metallic wear ring materials are filled PTFE and compounds of PTFE and fabric materials
Wear rings are fitted easily into closed grooves on the piston or in the gland The number of wear rings to be used will depend on the radial forces and the permissible surface pressure of the wear ring material in addition to the length of stroke the diameter and other design factors
Advantagebull Very good anti-friction behaviourbull No stick-slip effectbull Good dry running characteristicsbull Good wear resistance with long service life

The wear rings can be used in all hydraulic oil media
PTFE materials have a low coefficient of friction but also low load caracteristics They are therefore better used for low load applications
Thermoplastic materials have a higher friction coefficient but also high load characteristics and can be used in high pressure applications
Cuts
Wear rings are made with different cuts
X- Cut For reciprocating movement
Y- Cut For rotary movement
Z- Cut For reciprocating or rotary movements in contaminated systems to protect the seal
In extremely contaminated systems consideration should be given to the use of Code 07 material in-board of one of our seals with other wear ring materials in the out-board position

Solid back-up rings and O rings
Back-up rings are used in combination with axial and radial seals when the extrusion gap is too big for the required pressure and temperature
O rings made of PTFE are used in all applications in which the chemical resistance of conventional elastomer O rings is not adequate PTFE O rings can only be used as static seals PTFE lsquoOrsquo rings are manufactured by machining and can be produced in all sizes

Wear rings are designed to guide piston and the piston rods of power cylinders and to absorb the lateral forces which occur They also prevent metal to metal contact between sliding parts Wear rings are available in tape or machined rings
An important advantage is that metallic seizure cannot occur with the correct design The most frequently used non-metallic wear ring materials are filled PTFE and compounds of PTFE and fabric materials
Wear rings are fitted easily into closed grooves on the piston or in the gland The number of wear rings to be used will depend on the radial forces and the permissible surface pressure of the wear ring material in addition to the length of stroke the diameter and other design factors
Advantagebull Very good anti-friction behaviourbull No stick-slip effectbull Good dry running characteristicsbull Good wear resistance with long service life

The wear rings can be used in all hydraulic oil media
PTFE materials have a low coefficient of friction but also low load caracteristics They are therefore better used for low load applications
Thermoplastic materials have a higher friction coefficient but also high load characteristics and can be used in high pressure applications
Cuts
Wear rings are made with different cuts
X- Cut For reciprocating movement
Y- Cut For rotary movement
Z- Cut For reciprocating or rotary movements in contaminated systems to protect the seal
In extremely contaminated systems consideration should be given to the use of Code 07 material in-board of one of our seals with other wear ring materials in the out-board position

Solid back-up rings and O rings
Back-up rings are used in combination with axial and radial seals when the extrusion gap is too big for the required pressure and temperature
O rings made of PTFE are used in all applications in which the chemical resistance of conventional elastomer O rings is not adequate PTFE O rings can only be used as static seals PTFE lsquoOrsquo rings are manufactured by machining and can be produced in all sizes

Wear rings are designed to guide piston and the piston rods of power cylinders and to absorb the lateral forces which occur They also prevent metal to metal contact between sliding parts Wear rings are available in tape or machined rings
An important advantage is that metallic seizure cannot occur with the correct design The most frequently used non-metallic wear ring materials are filled PTFE and compounds of PTFE and fabric materials
Wear rings are fitted easily into closed grooves on the piston or in the gland The number of wear rings to be used will depend on the radial forces and the permissible surface pressure of the wear ring material in addition to the length of stroke the diameter and other design factors
Advantagebull Very good anti-friction behaviourbull No stick-slip effectbull Good dry running characteristicsbull Good wear resistance with long service life

The wear rings can be used in all hydraulic oil media
PTFE materials have a low coefficient of friction but also low load caracteristics They are therefore better used for low load applications
Thermoplastic materials have a higher friction coefficient but also high load characteristics and can be used in high pressure applications
Cuts
Wear rings are made with different cuts
X- Cut For reciprocating movement
Y- Cut For rotary movement
Z- Cut For reciprocating or rotary movements in contaminated systems to protect the seal
In extremely contaminated systems consideration should be given to the use of Code 07 material in-board of one of our seals with other wear ring materials in the out-board position

Uni-Seal mdash J40 - J42
Standard profiles Types J40 J41 and J42RADIAL SEALS
Type
J40
Type J40 utilises a wrapped and formed ribbon spring The design offers the utmost in spring deflection for otherwise difficult sealing applications Can be used for reciprocating and slow rotary motion in dynamic and static sealing Type 41 as Type J40 plus extended heel for high pressures
Type
J41
J42As Type 40 Due to the clamping of the flange the seal will be prevented from turning with the shaft This can occur with standard designs due to thermal and other effects with dynamic applications
Hardware dimensions as per pages 7 or 9

Solid back-up rings and O rings
Back-up rings are used in combination with axial and radial seals when the extrusion gap is too big for the required pressure and temperature
O rings made of PTFE are used in all applications in which the chemical resistance of conventional elastomer O rings is not adequate PTFE O rings can only be used as static seals PTFE lsquoOrsquo rings are manufactured by machining and can be produced in all sizes

Wear rings are designed to guide piston and the piston rods of power cylinders and to absorb the lateral forces which occur They also prevent metal to metal contact between sliding parts Wear rings are available in tape or machined rings
An important advantage is that metallic seizure cannot occur with the correct design The most frequently used non-metallic wear ring materials are filled PTFE and compounds of PTFE and fabric materials
Wear rings are fitted easily into closed grooves on the piston or in the gland The number of wear rings to be used will depend on the radial forces and the permissible surface pressure of the wear ring material in addition to the length of stroke the diameter and other design factors
Advantagebull Very good anti-friction behaviourbull No stick-slip effectbull Good dry running characteristicsbull Good wear resistance with long service life

The wear rings can be used in all hydraulic oil media
PTFE materials have a low coefficient of friction but also low load caracteristics They are therefore better used for low load applications
Thermoplastic materials have a higher friction coefficient but also high load characteristics and can be used in high pressure applications
Cuts
Wear rings are made with different cuts
X- Cut For reciprocating movement
Y- Cut For rotary movement
Z- Cut For reciprocating or rotary movements in contaminated systems to protect the seal
In extremely contaminated systems consideration should be given to the use of Code 07 material in-board of one of our seals with other wear ring materials in the out-board position

Type J40 utilises a wrapped and formed ribbon spring The design offers the utmost in spring deflection for otherwise difficult sealing applications Can be used for reciprocating and slow rotary motion in dynamic and static sealing Type 41 as Type J40 plus extended heel for high pressures
Type
J41
J42As Type 40 Due to the clamping of the flange the seal will be prevented from turning with the shaft This can occur with standard designs due to thermal and other effects with dynamic applications

Solid back-up rings and O rings
Back-up rings are used in combination with axial and radial seals when the extrusion gap is too big for the required pressure and temperature
O rings made of PTFE are used in all applications in which the chemical resistance of conventional elastomer O rings is not adequate PTFE O rings can only be used as static seals PTFE lsquoOrsquo rings are manufactured by machining and can be produced in all sizes

Wear rings are designed to guide piston and the piston rods of power cylinders and to absorb the lateral forces which occur They also prevent metal to metal contact between sliding parts Wear rings are available in tape or machined rings
An important advantage is that metallic seizure cannot occur with the correct design The most frequently used non-metallic wear ring materials are filled PTFE and compounds of PTFE and fabric materials
Wear rings are fitted easily into closed grooves on the piston or in the gland The number of wear rings to be used will depend on the radial forces and the permissible surface pressure of the wear ring material in addition to the length of stroke the diameter and other design factors
Advantagebull Very good anti-friction behaviourbull No stick-slip effectbull Good dry running characteristicsbull Good wear resistance with long service life

The wear rings can be used in all hydraulic oil media
PTFE materials have a low coefficient of friction but also low load caracteristics They are therefore better used for low load applications
Thermoplastic materials have a higher friction coefficient but also high load characteristics and can be used in high pressure applications
Cuts
Wear rings are made with different cuts
X- Cut For reciprocating movement
Y- Cut For rotary movement
Z- Cut For reciprocating or rotary movements in contaminated systems to protect the seal
In extremely contaminated systems consideration should be given to the use of Code 07 material in-board of one of our seals with other wear ring materials in the out-board position

Uni-Seal mdash J40 - J42
Standard profiles Types J40 J41 and J42RADIAL SEALS
Type
J40
Type J40 utilises a wrapped and formed ribbon spring The design offers the utmost in spring deflection for otherwise difficult sealing applications Can be used for reciprocating and slow rotary motion in dynamic and static sealing Type 41 as Type J40 plus extended heel for high pressures
Type
J41
J42As Type 40 Due to the clamping of the flange the seal will be prevented from turning with the shaft This can occur with standard designs due to thermal and other effects with dynamic applications
Hardware dimensions as per pages 7 or 9
Order example 1- 01050 01094J40Product codeCross section codeHardware indicator 1 = Radial shaft seal 2 = Radial piston sealHardware diameter (1050mm)Seal jacket materialSpring material
Solid back-up rings and O rings
Back-up rings are used in combination with axial and radial seals when the extrusion gap is too big for the required pressure and temperature
O rings made of PTFE are used in all applications in which the chemical resistance of conventional elastomer O rings is not adequate PTFE O rings can only be used as static seals PTFE lsquoOrsquo rings are manufactured by machining and can be produced in all sizes

Wear rings are designed to guide piston and the piston rods of power cylinders and to absorb the lateral forces which occur They also prevent metal to metal contact between sliding parts Wear rings are available in tape or machined rings
An important advantage is that metallic seizure cannot occur with the correct design The most frequently used non-metallic wear ring materials are filled PTFE and compounds of PTFE and fabric materials
Wear rings are fitted easily into closed grooves on the piston or in the gland The number of wear rings to be used will depend on the radial forces and the permissible surface pressure of the wear ring material in addition to the length of stroke the diameter and other design factors
Advantagebull Very good anti-friction behaviourbull No stick-slip effectbull Good dry running characteristicsbull Good wear resistance with long service life

The wear rings can be used in all hydraulic oil media
PTFE materials have a low coefficient of friction but also low load caracteristics They are therefore better used for low load applications
Thermoplastic materials have a higher friction coefficient but also high load characteristics and can be used in high pressure applications
Cuts
Wear rings are made with different cuts
X- Cut For reciprocating movement
Y- Cut For rotary movement
Z- Cut For reciprocating or rotary movements in contaminated systems to protect the seal
In extremely contaminated systems consideration should be given to the use of Code 07 material in-board of one of our seals with other wear ring materials in the out-board position

Wear rings are designed to guide piston and the piston rods of power cylinders and to absorb the lateral forces which occur They also prevent metal to metal contact between sliding parts Wear rings are available in tape or machined rings
An important advantage is that metallic seizure cannot occur with the correct design The most frequently used non-metallic wear ring materials are filled PTFE and compounds of PTFE and fabric materials
Wear rings are fitted easily into closed grooves on the piston or in the gland The number of wear rings to be used will depend on the radial forces and the permissible surface pressure of the wear ring material in addition to the length of stroke the diameter and other design factors
Advantagebull Very good anti-friction behaviourbull No stick-slip effectbull Good dry running characteristicsbull Good wear resistance with long service life

The wear rings can be used in all hydraulic oil media
PTFE materials have a low coefficient of friction but also low load caracteristics They are therefore better used for low load applications
Thermoplastic materials have a higher friction coefficient but also high load characteristics and can be used in high pressure applications
Cuts
Wear rings are made with different cuts
X- Cut For reciprocating movement
Y- Cut For rotary movement
Z- Cut For reciprocating or rotary movements in contaminated systems to protect the seal
In extremely contaminated systems consideration should be given to the use of Code 07 material in-board of one of our seals with other wear ring materials in the out-board position

Wear rings are designed to guide piston and the piston rods of power cylinders and to absorb the lateral forces which occur They also prevent metal to metal contact between sliding parts Wear rings are available in tape or machined rings
An important advantage is that metallic seizure cannot occur with the correct design The most frequently used non-metallic wear ring materials are filled PTFE and compounds of PTFE and fabric materials
Wear rings are fitted easily into closed grooves on the piston or in the gland The number of wear rings to be used will depend on the radial forces and the permissible surface pressure of the wear ring material in addition to the length of stroke the diameter and other design factors
Advantagebull Very good anti-friction behaviourbull No stick-slip effectbull Good dry running characteristicsbull Good wear resistance with long service life

The wear rings can be used in all hydraulic oil media
PTFE materials have a low coefficient of friction but also low load caracteristics They are therefore better used for low load applications
Thermoplastic materials have a higher friction coefficient but also high load characteristics and can be used in high pressure applications
Cuts
Wear rings are made with different cuts
X- Cut For reciprocating movement
Y- Cut For rotary movement
Z- Cut For reciprocating or rotary movements in contaminated systems to protect the seal
In extremely contaminated systems consideration should be given to the use of Code 07 material in-board of one of our seals with other wear ring materials in the out-board position

Wear rings are designed to guide piston and the piston rods of power cylinders and to absorb the lateral forces which occur They also prevent metal to metal contact between sliding parts Wear rings are available in tape or machined rings
An important advantage is that metallic seizure cannot occur with the correct design The most frequently used non-metallic wear ring materials are filled PTFE and compounds of PTFE and fabric materials
Wear rings are fitted easily into closed grooves on the piston or in the gland The number of wear rings to be used will depend on the radial forces and the permissible surface pressure of the wear ring material in addition to the length of stroke the diameter and other design factors
Advantagebull Very good anti-friction behaviourbull No stick-slip effectbull Good dry running characteristicsbull Good wear resistance with long service life

The wear rings can be used in all hydraulic oil media
PTFE materials have a low coefficient of friction but also low load caracteristics They are therefore better used for low load applications
Thermoplastic materials have a higher friction coefficient but also high load characteristics and can be used in high pressure applications
Cuts
Wear rings are made with different cuts
X- Cut For reciprocating movement
Y- Cut For rotary movement
Z- Cut For reciprocating or rotary movements in contaminated systems to protect the seal
In extremely contaminated systems consideration should be given to the use of Code 07 material in-board of one of our seals with other wear ring materials in the out-board position

Wear rings are designed to guide piston and the piston rods of power cylinders and to absorb the lateral forces which occur They also prevent metal to metal contact between sliding parts Wear rings are available in tape or machined rings
An important advantage is that metallic seizure cannot occur with the correct design The most frequently used non-metallic wear ring materials are filled PTFE and compounds of PTFE and fabric materials
Wear rings are fitted easily into closed grooves on the piston or in the gland The number of wear rings to be used will depend on the radial forces and the permissible surface pressure of the wear ring material in addition to the length of stroke the diameter and other design factors
Advantagebull Very good anti-friction behaviourbull No stick-slip effectbull Good dry running characteristicsbull Good wear resistance with long service life

The wear rings can be used in all hydraulic oil media
PTFE materials have a low coefficient of friction but also low load caracteristics They are therefore better used for low load applications
Thermoplastic materials have a higher friction coefficient but also high load characteristics and can be used in high pressure applications
Cuts
Wear rings are made with different cuts
X- Cut For reciprocating movement
Y- Cut For rotary movement
Z- Cut For reciprocating or rotary movements in contaminated systems to protect the seal
In extremely contaminated systems consideration should be given to the use of Code 07 material in-board of one of our seals with other wear ring materials in the out-board position

Wear rings are designed to guide piston and the piston rods of power cylinders and to absorb the lateral forces which occur They also prevent metal to metal contact between sliding parts Wear rings are available in tape or machined rings
An important advantage is that metallic seizure cannot occur with the correct design The most frequently used non-metallic wear ring materials are filled PTFE and compounds of PTFE and fabric materials
Wear rings are fitted easily into closed grooves on the piston or in the gland The number of wear rings to be used will depend on the radial forces and the permissible surface pressure of the wear ring material in addition to the length of stroke the diameter and other design factors
Advantagebull Very good anti-friction behaviourbull No stick-slip effectbull Good dry running characteristicsbull Good wear resistance with long service life

The wear rings can be used in all hydraulic oil media
PTFE materials have a low coefficient of friction but also low load caracteristics They are therefore better used for low load applications
Thermoplastic materials have a higher friction coefficient but also high load characteristics and can be used in high pressure applications
Cuts
Wear rings are made with different cuts
X- Cut For reciprocating movement
Y- Cut For rotary movement
Z- Cut For reciprocating or rotary movements in contaminated systems to protect the seal
In extremely contaminated systems consideration should be given to the use of Code 07 material in-board of one of our seals with other wear ring materials in the out-board position

Wear rings are designed to guide piston and the piston rods of power cylinders and to absorb the lateral forces which occur They also prevent metal to metal contact between sliding parts Wear rings are available in tape or machined rings
An important advantage is that metallic seizure cannot occur with the correct design The most frequently used non-metallic wear ring materials are filled PTFE and compounds of PTFE and fabric materials
Wear rings are fitted easily into closed grooves on the piston or in the gland The number of wear rings to be used will depend on the radial forces and the permissible surface pressure of the wear ring material in addition to the length of stroke the diameter and other design factors
Advantagebull Very good anti-friction behaviourbull No stick-slip effectbull Good dry running characteristicsbull Good wear resistance with long service life

Wear rings are designed to guide piston and the piston rods of power cylinders and to absorb the lateral forces which occur They also prevent metal to metal contact between sliding parts Wear rings are available in tape or machined rings
An important advantage is that metallic seizure cannot occur with the correct design The most frequently used non-metallic wear ring materials are filled PTFE and compounds of PTFE and fabric materials
Wear rings are fitted easily into closed grooves on the piston or in the gland The number of wear rings to be used will depend on the radial forces and the permissible surface pressure of the wear ring material in addition to the length of stroke the diameter and other design factors
Advantagebull Very good anti-friction behaviourbull No stick-slip effectbull Good dry running characteristicsbull Good wear resistance with long service life

The wear rings can be used in all hydraulic oil media
PTFE materials have a low coefficient of friction but also low load caracteristics They are therefore better used for low load applications
Thermoplastic materials have a higher friction coefficient but also high load characteristics and can be used in high pressure applications
Cuts
Wear rings are made with different cuts
X- Cut For reciprocating movement
Y- Cut For rotary movement
Z- Cut For reciprocating or rotary movements in contaminated systems to protect the seal
In extremely contaminated systems consideration should be given to the use of Code 07 material in-board of one of our seals with other wear ring materials in the out-board position
