FEATURES AND BENEFITS MULTIPLE LOCKING METHODS SKWEZLOC® CONCENTRIC LOCKING COLLAR
SKWEZLOC is a concentric locking collar clamp design that results in near perfect concentricity of the shaft to the bearing bore and maintains near perfect ball path roundness, while reducing fretting corrosion. This design eliminates the shaft damage of setscrew locking, and minimizes bearing induced vibration for smoother, quieter operation. The collar has a TORX Plus head cap screw that outlasts stripping 12 times longer than hex head cap screws. The Skwezloc locking collar has been redesigned to accommodate “Commercial” grade Turned and Polished (T&P) shaft tolerances with improved lock reliability on Turned, Ground and Polished (TG&P) shaft tolerances. The new design has been a rolling implementation beginning in 2017 continuing through 2018.
SETSCREW LOCKING 120° spaced, balanced three point contact minimizes inner ring distortion vibration, reduces noise, and improves reliability. Precision manufactured diamond faceted setscrews contributes to improved clamping and resistance to back out.
SEALING Positive contact molded nitrile rubber contact seal with an auxiliary flinger element standard. The contact seal allows grease purge and helps keep contamination out of the bearing while the flinger provides a rotating shield that directs contamination away from the seal.
SEALED FOR LIFE The Sealmaster Material Handling Bearings are supplied with a plug in the housing to prevent relubrication. A standard lubrication fitting is supplied loose in the box for those customers who prefer relubricating the bearings. END CAPS The Sealmaster Material Handling Bearings housing are machined to accept an optional safety yellow polymer snap on end cap to cover rotating shafts, allowing users to better conform to OSHA requirements for personal protection from rotating shafts. The end cap can easily snap into the housing without the need for special tooling.
ANTI-ROTATION RIVET An Anti-rotation rivet prevents outer ring creep, or rotation, within the housing.
ZONE HARDENED INNER RACE Sealmaster incorporates a unique heat treat process that hardened the inner race only where it is needed...under the ball path. The zone hardened inner race results in improved lock reliability as a result of less distortion at setscrew location and improved thread conformity resulting in improved clamping and resistance to setscrew back-out.
SOLID CAST IRON BASE Solid bases are standard on Sealmaster Material Handling ball bearing pillow blocks. The solid base provides improved stability, resistance to shock and vibration and prevents frame buckling under base compared to semi-solid and hollow mounting bases.
NAMEPLATE Metal nameplate riveted to the housing allows for easy identification even after years of operation.
