Blue Brute Bearings - Locking configurations

Self-Aligning Spherical Roller Bearings

Eccentric lock shown

Blue Brute roller bearings represent decades of bearing technology and utilize world leading design for heavy-duty applications. Due to the number and size of the two rows of symmetrical barrel shaped rollers combined with precision guiding they have extreme load and speed capacity. The double row spherical bearings used in Blue Brute bearings feature extra large spherical rollers. Bearings from size 08 to 20 (1-7/16î to 4î) have steel window cages. Bearings size 22 and over have machined brass cages. These bearings work at full capacity regardless of limited shaft and housing misalignment. Blue Brute Bearings allow misalignment in any direction up to 2 degrees from center. Our rollers align freely between the spherical outer and inner ring and contact at an angle allowing heavy radial and thrust loads in either direction. Crowned roller ends result in unaffected performance under dynamic, static, or oscillatory conditions with heavy loads in a combination of planes.

EC Series - Standard Eccentric Locking Collar

Unsurpassed holding in heavy thrust, reversing or shock loading.

We guarantee this bearing will not come loose if

installed on a precision ground shaft (see page 60)

CL Series - Concentric Locking Collar (set screw lock)

Set screw locking 2 set screws @ 60 , provides maximum holding with minimal run out. Knurled point set screws provide positive locking.

DV Series - Tapered Adapter Sleeve

DV Bearings are a drop in replacement for common Ameri-can Set-screw mounted units, re-sults in extremely high load capacities compared to any collar mounted unit. Best concentricity for high speeds.

TA Series - Tapered Adapter Sleeve

TA Bearings are a direct drop in replacement for SAF/SN split cap housing dimensions results in superior sealing and integrally robust housing. Best concentricity for high speeds.

Double Lip Seal - ’C’ Contacting, non-purgingThis seal is the same as the ‘B’ seal except it is manufactured with

(Viton*) seal material. Viton* has excellent chemical and abrasion resistance and operates at higher temperatures

than our standard nitrile rubber seal.

*Viton is a registered trade mark of Dupont

Triple Lip Seal - ‘N’ - Contacting, self purging This seal is a triple lip seal, medium contact. The ‘N’ seal is made with Viton* has excellent chemical and abrasion resistance andoperates at higher temperatures than nitrile rubber. The seal is similar to our ‘M’ seal.

.

Double Lip Seal - ’B’ Contacting, non-purgingThis seal incorporates a double lip seal of nitrile rubber with a garter spring for maximum contact. It is complete with a heavy duty steel shield that protects the seal from larger pieces of debris that might dam-age the rubber seal. This seal works well in applications with oil lubrication and is designed for extreme moisture, fine dust or extremely dirty applications.

Standard Seal - ‘M’ Contacting, self purging This seal is a triple lip seal, medium contact. The ‘M’ seal offers supe-rior sealing in moist and dirty applications. Our ‘M’ seals provide excellent lubrication retention, but will allow ex-cess grease to purge from the bearing cavity. The “M” seal is madefrom nitrile rubber and has excellent chemical resistance. This seal is also completely coated with rubber for corrosion resistance.

Blue Brute- Bearing Seals

Sealing arrangementsBlue Brute bearings are offered with a large number of primary and secondary

sealing options. We assemble our bearings to order and different combinations of seals can be shipped easily from stock.

These seals are installed between the inner ring of the bearing and the housing. They are held securely in place by our assembly nut. Primary seals can be contacting or non-contacting, purging or non-purging and are available in several material compounds for different applications.

Blue Brute- Bearing Seals

Teflon Seal - ‘T’ non-contacting, non-purging The Teflon floating seal consists of a Teflon ring pressed onto the inner ring of the bearing. This Teflon ring floats between two pieces of formed steel. This seal was developed for high speed applications involving dirty conditions or moisture effected areas. Teflon sustains high temperatures and is impervious to almost all chemicals.

Primary Seals - continued

Secondary Seals

In many circumstances bearings fail due to premature seal failure. This is usually the result of a tough operating environment or over lubrication. QM Bearings has developed sec-ondary sealing covers that offer an extra sealing barrier and protection to the primary seal. These economical covers are easily outfitted on any Blue Brute bearing unit. They are ordered as separate parts and are not shown in the bearing part number.

Closed End covers Open End covers

Combination seals Blue Brute Bearings can be ordered with a combination of differentseals within the same bearing. Often a purging seal will be combinedwith a non-purging seal on the heavily contaminated side. To order the combination seal just add the second seal letter to the

bearing part number. For example: QMP13J207SMB will be shipped with the ’M’ seal on the collar side, B seal on the opposite side.

The Purging Relief Valve ‘R’

Purging relief valves, which can be ordered installed on all housing styles. This valve works with ‘T’, ‘B’ and ‘C’ seal installations. The purging relief valve opens at a pre-determined pressure, exhausts and expels lubrication from the bearing cavity where excessive lubricant pressure is not desirable.

The compression couplings made by QM Bearings have an improved design for lighter weight withoutcompromising the integrity of the coupling. Priced competitively and guaranteed for life, the cast steel couplingsare an excellent choice for joining two shafts of the same size. This design is also known as a “rigid clamp style”coupling.

Our compression couplings are manufactured for tough applications where strength is important. Thecompression couplings are bored to the shaft size then split. The splitting of the couplings forms a gap, whichthen allows the coupling to compress when clamping the two halves together on the shafts. They are easilyremoved by loosening and removing the bolts. To prevent shaft deflection the couplings should be mountedclose to a support bearing if possible.

Available for shaft sizes 1-7/16” through 4-1/2” or sizes not listed are available upon request.

QUICK-Flex couplings, made by QM Bearings,connect rotating shafts used by pumps, hydraulics,

motors, reducers and compressors operating in harshenvironments.

The coupling consists of two toothed couplinghalves, or hubs, which are attached to the drive anddriven shaft. A urethane insert interlocks around thetwo hubs and provides a simple yet effective drivemechanism.

A standard cover is secured to the coupling hub byeither snap ring or bolts.

Vertical and horizontal split covers are attached bybolts to prevent the cover from opening, contain theaxial load under higher speeds and double the

misalignment capabilities.The urethane elastomer

insert, sandwiched between thetoothed hubs, results inproduct advantages unmatchedby other coupling designs suchas jaw, grid, tire, gear and chain couplings.

The cushioning effect absorbs shock loads, reducesvibration and accepts a certain amount ofmisalignment due to the flexible nature of the insert.

Depending on temperature and torque loadrequirements, you may choose one of four differentelastomer compounds. The only part that needs to bereplaced is the elastomer insert.

When replacing the insert, there’s no need to movethe hub or realign anything.

It requires no lubrication and the only part youneed to stock is the elastomer insert, thereby reducinginventory costs.
