Spherical Roller Bearings

23034 CCK/W33 Spherical Roller Bearings

Spherical roller bearings can accommodate heavy loads in both directions. They are self-aligning and accommodate misalignment and shaft deflections, with virtually no increase in friction or temperature. The design includes features to facilitate relubrication. The bearings can be used in a modular system, including housings, sleeves and nuts.

Accommodate misalignment
High load carrying capacity
Relubrication features
Low friction and long service life
Increased wear resistance
