21309 E

Spherical roller bearing with relubrication features
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
