Spherical roller bearings

Spherical roller bearings consist of an outer ring with a spherical raceway, a double raceway inner ring, one or two cages and a set of spherical rollers. Since the center of the outer ring spherical raceway is consistent with the bearing center, it has self-aligning performance and can automatically adjust the tilt or shaft deflection caused by the angular error between the shaft and the bearing seat.

Spherical roller bearings can withstand large radial loads and bidirectional axial loads. Especially suitable for bearing heavy loads or shock and vibration loads. However, the allowable working speed of spherical roller bearings is relatively low.
