Spherical Roller Bearing

Product Detail
product list

Spherical roller bearings have two arc-shaped raceways on the inner ring and a spherical raceway on the outer ring. Since the bearing center coincides with the curvature center of the outer ring, the bearing has self-aligning capability. The allowable misalignment angle is generally 1°–2.5°, making it especially suitable for applications where shaft deflection or inclination may occur. These bearings can also withstand moderate axial loads in either direction, but are not suitable for pure axial loading. The contact line between the roller generatrix and the raceway is relatively long, resulting in higher frictional torque and a lower limiting speed compared to cylindrical roller bearings.

There are mainly two structural types: CC type—equipped with a stamped steel cage, no flange on the inner ring, and an axially movable center flange; CA type—typically uses a solid brass cage.

Spherical roller bearings are primarily used in applications with heavy loads and where the rotating shaft may experience deflection or misalignment.
