Spherical roller bearings have two rows of symmetrical rollers, a common sphered outer ring raceway and two inner ring raceways inclined at an angle to the bearing axis. The centre point of the sphere in the outer ring raceway is at the bearing axis. And its features:

1.Accommodate misalignment

Spherical roller bearings are self-aligning like self-aligning ball bearings or CARB bearings.

2.High load carrying capacity 

Spherical roller bearings are designed to accommodate both heavy radial loads and axial loads in both directions.

3.Long service life

The rollers are manufactured to such tight dimensional and geometrical tolerances that they are practically identical in a roller set. The symmetrical rollers self-adjust, providing optimal load distribution along the roller length and together with the special profile prevent stress peaks at the roller ends.

4.Low friction

Self-guiding rollers keep friction and frictional heat at low levels ( fig. 5 ). A floating guide ring guides unloaded rollers so that they enter the load zone in the optimal position.
