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.

Antifriction bearing with seal arrangement

A pin type retainer for roller bearings is stamped in one piece from flat metal stock. The flat metal is first drawn into a cup shape having a broad flange around an open first end and a closed second end. The closed end provides solid support and alignment while stamping pins from the broad flange. The pins are then final shaped by swaging or machining into cross sectional forms for a variety of applications. The second end is then opened to form a ring. The pin type retainer can be modified for use with a retaining ring or a seal against contaminants. The pin type retainer can be formed from a variety of materials, including steel. An embodiment using plastic resin is also disclosed.
