Spherical Roller Bearings

22328 CCKJA/W33VA405 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. This bearing design offers excellent performance in many types of vibrating machinery. 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
Accommodate very high vibration levels
Low friction and long service life
Increased wear resistance
