BS2-2315-2RSK/VT143

Spherical roller bearing with tapered bore, 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
