Spherical Roller Bearings
Spherical roller bearings have two raceways on the inner ring and a spherical raceway, along with spherical rollers, on the outer ring. Because the center of the raceway on the outer ring aligns with the center of the entire bearing, these bearings are self-aligning. They automatically adjust the eccentricity whether it's regarding the error of mounting bearings in the housing or the bending of the shaft.
These bearings operate normally when subjected to acute angles of up to 1 to 25 degrees between the center of the outer ring and the inner ring. They can accommodate radial loads and axial loads in both directions, with special radial load capacity allowing the bearings to withstand heavy loads and impact loads.

Spherical roller bearings are widely used in engineering machinery such as excavators and cranes for rotation systems, as well as in the main bearings of the metallurgical industry and wind power system.
