Spherical Roller Bearings
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.
- Accommodate misalignment
Spherical roller bearings are self-aligning like self-aligning ball bearings or CARB bearings.
- High load carrying capacity
Spherical roller bearings are designed to accommodate both heavy radial loads and axial loads in both directions.
- 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.
- Low friction
Self-guiding rollers keep friction and frictional heat at low levels. A floating guide ring guides unloaded rollers so that they enter the load zone in the optimal position.
All SKF spherical roller bearings contain strong window- or prong-type cages.
