Spherical roller bearings operate in arduous condi-tions. The spherical rollers can be symmetrical or unsym-metrical and are self-aligning in the outer ring sphered raceway. Thus, the possible coaxiality deviations of the supporting bearings as well as shaft bending can be compensated.

Spherical roller bearings are manufactured in the following constructive versions, depending on the bearing size and series:
