BS2-2207-2RS/VT143

Spherical roller bearing with integral sealing and 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. Under normal operating conditions, sealed bearings are almost maintenance-free, keeping service costs and grease consumption low. The design includes features to facilitate relubrication.

  • Accommodate misalignment
  • High load carrying capacity
  • Sealed for increased reliability, with relubrication features
  • Low friction and long service life
  • Increased wear resistance
