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
