Blue Brute Bearings - Locking configurationsSelf-Aligning Spherical RollerBearingsEccentric lock shownBlue Brute roller bearings represent decades of bearing technology and utilize world leadingdesign for heavy-duty applications. Due to the number and size of the two rows of symmetrical barrelshaped 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 sphericalrollers. Bearings from size 08 to 20 (1-7/16” to 4”) have steel window cages. Bearings size 22 and overhave 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 alignfreely between the spherical outer and inner ring and contact at an angle allowing heavy radial andthrust 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 - Eccentric LockAccepts heavy thrust loadsDV / TA - TaperedAdapter LockCL - Set Screw LockAccepts light thrust loadsAccepts medium thrust loadsEC Series Eccentric LockingCollarCL Series Concentric LockingCollar (set screw lock)DV Series Tapered AdapterSleeveTA Series Tapered AdapterSleeveUnsurpassed holding inheavy thrust, reversing orshock loading.Set screw locking 2 setscrews @ 60º, providesmaximum holding withminimal run out.

Blue Brute - Bearing SealsSealing arrangementsBlue Brute bearings are offered with a large number of primary and secondarysealing options. We assemble our bearings to order and different combinations of seals can beshipped easily from stock.Primary SealsThese seals are installed between the inner ring of the bearing and the housing. Theyare held securely in place by our assembly nut. Primary seals can be contacting ornon-contacting, purging or non-purging and are available in several material compounds fordifferent applications.Standard Seal - ‘M’ Contacting, self purgingThis seal is a triple lip seal, medium contact. The ‘M’ seal offers superior sealing in moist and dirty applications.Our ‘M’ seals provide excellent lubrication retention, but will allow excess grease to purge from the bearing cavity. The “M” seal is madefrom nitrile rubber and has excellent chemical resistance. This seal isalso completely coated with rubber for corrosion resistance.Triple Lip Seal - ‘N’ - Contacting, self purgingThis seal is a triple lip seal, medium contact. The ‘N’ seal ismade 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 garterspring for maximum contact. It is complete with a heavy duty steelshield that protects the seal from larger pieces of debris that might damage the rubber seal. This seal works well in applications with oillubrication and is designed for extreme moisture, fine dust or extremelydirty applications.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 excellentchemical and abrasion resistance and operates at higher temperaturesthan our standard nitrile rubber seal.*Viton is a registered trade mark of DupontFeatures and BenefitsPage 2Secondary sealConfigurations - Page 4How to orderSecondary Seal-Page 10TemperatureLimitations - Page 11SpeedLimitations - Page 12Chemical CompatibilityChart - Page 132-135Page 3
Blue Brute - Bearing SealsPrimary Seals - continuedTeflon Seal - ‘T’ non-contacting, non-purgingThe Teflon floating seal consists of a Teflon ring pressed onto theinner ring of the bearing. This Teflon ring floats between twopieces of formed steel. This seal was developed for high speedapplications involving dirty conditions or moisture effected areas.Teflon sustains high temperatures and is impervious to almost allchemicals.Combination sealsBlue 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 thebearing part number.For example: QMP13J207SMB will be shipped with the ’M’ sealon 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 reliefvalve opens at a pre-determined pressure, exhausts and expelslubrication from the bearing cavity where excessive lubricantpressure is not desirable.(actual size)Secondary SealsIn many circumstances bearings fail due to premature seal failure. This is usually theresult of a tough operating environment or over lubrication. QM Bearings has developed secondary 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 orderedas separate parts and are not shown in the bearing part number.Closed End coversHow to orderPrimary Seals - Page 3Secondary sealConfigurations - Page 4Open End coversHow to orderSecondary Seal-Page 10TemperatureLimitations - Page 11SpeedLimitations - Page 12Chemical CompatibilityChart - Page 132-135Page 4
Blue Brute CS - Closed End CoverThese snap on covers are designed to be virtually indestructible and extremely convenient. They are made from structural Urethane and install easily.

Blue Brute DR - Open End Covers / SealsThis snap on cover is made from an almost indestructible urethane for repeated use. Our standardtriple lip seal made from nitrile rubber or optional Viton* seal attaches to the open end cover. This triplelip seal can move within the opening to accommodate misalignment while maintaining full contact to theshaft for positive sealing. A grease fitting is installed on the cover so the cover cavity can be filled withgrease for extra protection against contamination. The DR seal can be purchased separately.We offer a special order ‘QMPPD” triple lip urethane compound seal formulated by QM to handleextreme abrasion resistance requirements.

Blue Brute - UFP Secondary Shaft Seal for Flange BlocksDue to the mounting nature of a flange block, a regular snap-in cover will not work on the back side. For this application, we provide an optional secondary sealing plate that fits flush with the back of the housing and creates alabyrinth over the inner ring. A V-ring can then be fitted over the shaft to provide another contamination barrier,our CC collars can also be used with the UFP Plate. The UFP Plate is available with all QM Bearings Flangeblocks—square and round.UFP seal series dimensionsSealPart .553.073.564.105.13Blue Brute - Secondary Shaft Collar / SealSecondary shaft collar provides an additional sealing arrangement for flange cartridge and flange block stylebearings.

The double row spherical bearings used in Blue Brute bearings feature extra large spherical rollers. Bearings from size 08 to 20 (1-7/16" to 4") 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.
