Be sure to read this before handling the products. Refer to the back cover for Safety Instructions. For Actuator Precautions, refer to Handling Precautions for SMC Products and the Operation Manual on the SMC website, http://www.smcworld.com
Design
Warning1. Check the application.
This product is a shaft coupling for linear reciprocating motion used to absorb slight misalignment of the workpiece and the cylinder during linear motion. It is not a shaft coupling for rotation. Do not use it for an application in which rotation or oscillation is applied.
2. Use a foot type or flange type bracket to mount a cylinder.If a clevis type or trunnion type bracket is used, the cylinder shaft will not be fixed and it will be able to rotate. This mounting method, which exceeds the allowable eccentricity and rotating angle of the floating joint, may cause breakage or malfunction of the product.
3. Use within the range of specifications.Operation of the product under loading or with eccentricity outside of allowable specification may cause breakage or malfunction.
4. Use a cylinder with a built-in cushion mechanism.When a driven object is stopped, ensure the impact force of the object being transferred to the floating joint is prevented by using a cylinder with a built-in cushion mechanism (rubber cushion or air cushion).To stop the cylinder at the intermediate position, use an external shock absorbing mechanism such as a shock absorber. If the cushion mechanism or the external shock absorbing mechanism is not used, an excessive impact force will be generated when stopping the cylinder and this may cause breakage or malfunction of the product.
5. Install an external stopper to avoid run-away of the equipment.If there is a risk of equipment damage or injury in the case of equipment running out of control or dropping off the driven object due to loose connecting screws, install an external stopper to avoid run-away of the equipment.
6. Play in the axial directionThe JT series has play in the axial direction. (Default: 0.15 mm or less) When positioning the driven object, avoid the influence of play using a knock pin or external stopper.
Mounting
Warning1. Maintenance space
Allow sufficient space for maintenance and inspection.
2. Operate the socket by hand before mounting to ensure it moves smoothly.The dust cover may stick to the socket. Move the dust cover at the base of the socket with fingers, or twist the socket right and left gently to free it before mounting.
Mounting
Warning3. Tighten the product to the appropriate torque for the
screw size using an appropriate tool. In addition, apply a locking adhesive.When connecting the driven object to the cylinder rod with a floating joint, hold the octagonal and square parts with an appropriate wrench and tighten the floating joint to the appropriate tightening torque. Refer to the table on the right for the appropriate tightening torque.The floating joint may be broken or malfunction if parts other than the octagonal or square parts are gripped and rotated with pliers or a wrench, or if it is tightened to an excessive torque. As a countermeasure against loosening caused by vi-bration or other reasons, apply locking adhesive.

Operating Environment
Warning1. Avoid using in a location where the product could
be splashed by liquids such as coolants and water. Also, avoid locations where exposed to a large amount of dust or foreign matter.If liquid or dust gets inside the floating joint from the gap of the dust cover, it may cause a malfunction. Install a protective cover if the product is directly splashed by liquids or foreign matter can be accumulated.
2. Do not expose the product to direct sunlight for an extended period of time.

Operation
Warning1. Use the product so that the kinetic energy does not
exceed the allowable value of the cylinder.The JCM series cylinder is recommended to be used with the JT series. When operating the equipment, adjust the stroke end velocity according to the load so that the kinetic energy is no more than that of the allowable value of the cylinder.
Speed when stopping (stroke end velocity) ≈ Average speed x 1.4
Also, when using cylinders or equipment other than the JCM series, adjust the stroke end velocity according to the load so that the kinetic energy is no more than that of the allowable value of the JCM series.
Maintenance
Warning1. Implement regular inspections as necessary when
starting-up etc. Confirm that there is no loosening of the connection between the driven object and the cylinder.When the equipment is operated at high frequency, screws and play in the axial direction can increase and occur easily over time. Make sure to inspect the equipment before starting work to confirm that the screws have not been loosened and the play has not significantly increased.
2. If the play in the axial direction becomes larger or abnormal operation is found, replace the product.Play in the axial direction of the floating joint will increase over time, even if the product is used constantly. If the amount of play becomes excessive to the application or the operation is inflexible, replace the product itself.
3. Confirm that there is no weakening of the rubber bumper within the cylinder or adjustment error of the air cushion.If the rubber bumper of the cylinder is weakened or the adjust-ment of the air cushion is incorrect, an excessive impact force will be generated when the cylinder reaches its end of stroke, this may cause breakage or malfunction of the product. Replace the cylinder if the rubber bumper is weakening or readjust the air cushion if an adjustment error is found.
Other
Caution1. Chromate treatment is performed for the bowl of JT
series for rust prevention. There may be slight variation in the evenness and tone of color, but this does not affect the resistance against rust or product performance.If the product with even tone of color is required for the appli-cation, it is available as a special request. Please contact SMC.

Mounting Maintenance
Warning Warning1. To screw the male threads of the rod into the female
threads of the socket or the case, make sure that it does not bottom out.If the floating joint is used with its rod bottomed out, the stud will not be able to float, causing damage.For the screw-in depth of the female threads, refer to the di-mensions (page 1132). As a rule, after the rod bottoms out, back off 1 to 2 turns.
2.The dust cover may stick to the stud. Move the dust cover at the base of the stud with fingers, or twist the stud right and left gently to free them.And when screwing stud or socket, or case in the driven ob-ject, make sure to screw them in the state that dust cover has been removed from the case. If screwing without removing dust cover, dust cover might be broken.
3.To use a floating joint to connect the cylinder rod to a driven body, secure it in place by applying a torque that is appropriate for the thread size. Also, if there is a risk of loosening during operation, take mea-sures to prevent loosening, such as using a locking pin or thread adhesive.In the event that the connected portion becomes loose, the driven body might lose control or fall off, leading to equipment damage or injury to personnel.
4. This product is dedicated to the linear motion. The threaded portion can be rotated, but this product is not a fitting designed for rotational axis. So, do not use for rotational applications.
5. Use the product at 25% or less of the allowable ki-netic energy of the cylinder. When a driven object is stopped, be sure to prevent the impact force of the object being transferred to the product by adding the cushion mechanism of a cylinder or other cush-ioning devices such as a shock absorber. Other-wise, the impact force may exceed the maximum tensile and compressive force of the product, caus-ing breakage.
1. Do not reuse if disassembled.High strength adhesive is applied to the portion of the connec-tion that is threaded to prevent it from loosening, and it must not be disassembled. If it is forcefully disassembled, it could lead to damage.

1. To screw the male threads of the rod into the female threads of the socket or the case, make sure that it does not bottom out.If the floating joint is used with its rod bottom out, the stud will not be able to float, causing damage.For the screw-in depth of the female threads, refer to the dimensions (page 1138). As a rule, after the rod bottoms out, back off 1 to 2 turns.
2. The dust cover may adhere to the stud. In this case, move the dust cover at the neck of the stud by the finger or twist the stud slightly left or right to break in the dust cover before use.Additionally, when screwing the stud and socket or the case into a driven body, screw in such parts with the dust cover removed. When screwing in such parts without removing the dust cover, this may cause damage to the dust cover.
3. To use a floating joint to connect the cylinder rod to a driven body, secure it in place by applying a torque that is appropriate for the thread size. Also, if there is a risk of loosening during operation, take measures to prevent loosening, such as using a locking pin or thread adhesive.In the event that the connected portion becomes loose, the driven body might lose control or fall off, leading to equipment damage or injury to personnel.
4. This product is not a rotary joint. So, the product cannot be used for rotational or rotation acting applications.
5. Be sure to use the cushion mechanism of the cylinder or the buffer mechanism, such as the shock absorber so that any impact force is not applied to the floating joint when stopping a driven body. If there is no buffer mechanism, an excessive impact force is generated. As a result, the tensile compression force of the floating joint may exceed its maximum level.

1. The black zinc chromate treatment is applied to the material surfaces of the case, flange and foot. However, the white deposit may rarely occur on the surface. This white deposit does not affect the product functions. However, if the white deposit becomes a problem from a viewpoint of appear-ance, special products with the surface treatment changed to the electroless nickel plating are also available. For details, please contact SMC.

Be sure to read before handling.Refer to front matter 57 for Safety Instructions.
1. To screw the male threads of the rod into the female threads of the socket or the case, make sure that it does not bottom out. If the floating joint is used with its rod bottomed out, the stud will not be able to float, causing damage. For the screw-in depth of the female threads, refer to the dimensions (page 1142). As a rule, after the rod bottoms out, back off 1 to 2 turns.
2. The dust cover may adhere to the stud. In this case, move the dust cover at the neck of the stud by the finger or twist the stud slightly left or right to break in the dust cover before use.
Additionally, when screwing the stud and socket or the case into a driven body, screw in such parts with the dust cover removed. When screwing in such parts without removing the dust cover, this may cause damage to the dust cover.
3. To use a floating joint to connect the cylinder rod to a driven body, secure it in place by applying a torque that is appropriate for the thread size. Also, if there is a risk of loosening during operation, take measures to prevent loosening, such as using a locking pin or thread adhesive.In the event that the connected portion becomes loose, the driven body might lose control or fall off, leading to equipment damage or injury to personnel.
4. This product is not a rotary joint. So, the product cannot be used for rotational or rotation acting applications.
5. Be sure to use the cushion mechanism of the cylinder or the buffer mechanism, such as the shock absorber so that any impact force is not applied to the floating joint when stopping a driven body. If there is no buffer mechanism, an excessive impact force is generated. As a result, the tensile compression force of the floating joint may exceed its maximum level.
1. Do not reuse if disassembled.High strength adhesive is applied to the portion of the connection that is threaded to prevent it from loosening, and it must not be disassembled. If it is forcefully disassembled, it could lead to damage.

1. The black zinc chromate treatment is applied to the material surfaces of the case, flange and foot. However, the white deposit may rarely occur on the surface. This white deposit does not affect the product functions. However, if the white deposit becomes a problem from a viewpoint of appear-ance, special products with the surface treatment changed to the electroless nickel plating are also available. For details, please contact SMC.

Also, if there is a risk of loosening during opera-tion, take measures to prevent loosening, such as using a locking pin or thread adhesive.In the event that the connected portion becomes loose, the driven body might lose control or fall off, leading to equipment damage or injury to personnel.
4. This product is not a rotary joint. So, the product cannot be used for rotational or rotation acting applications.
5. Be sure to use the cushion mechanism of the cyl-inder or the buffer mechanism, such as the shock absorber so that any impact force is not applied to the floating joint when stopping a driven body. If there is no buffer mechanism, an excessive impact force is generated. As a result, the tensile compression force of the floating joint may exceed its maximum level.
1. Do not reuse if disassembled.High strength adhesive is applied to the portion of the connection that is threaded to prevent it from loosening, and it must not be disassembled. If it is forcefully disassembled, it could lead to damage.

1. The black zinc chromate treatment is applied to the material surfaces of the case, flange and foot. However, the white deposit may rarely occur on the surface. This white deposit does not affect the product functions. However, if the white deposit becomes a problem from a viewpoint of appear-ance, special products with the surface treatment changed to the electroless nickel plating are also available. For details, please contact SMC.
