Spherical roller bearings
Self-aligning roller bearings are bearings for the most severe fields of application and contain two rows of symmetrical barrel rollers which set freely in the hollow-spherical outer raceway. Shaft deflections and alignment errors can be compensated by this design.
Self-aligning roller bearings are provided with a maximum number of rollers with large diameter and length. Uniform distribution of stresses and a high supporting capacity are achieved by the close contact between the rollers and the raceway.
