Self-aligning roller bearing

Self-aligning roller bearings have two pairs of symmetrical spherical rollers that can freely realize self-aligning on the concave spherical raceway of the outer ring. Thus, the concentricity error formed after the shaft bending deformation at the bearing installation position can be compensated. Bearings of this kind can bear larger radial loads two-way axial loads and combined loads. They are applicable to the occasions of carrying heavy loads and shock loads in low speed and medium speed.
