Antifriction bearing with seal arrangement

摘要

A spherical roller bearing has a seal at each axial end of the inner ring-outer ring annulus. Each seal has two spaced apart metal parts. Elastomeric seal lips are bonded to one metal part and extend into wiping contact with the other metal part. The spherical roller bearings described have three seal lips. In one embodiment two seal lips are bonded to one metal part and one seal lip is bonded to the other metal part. In the other embodiment the three seal lips are bonded to one metal part.
