Abstract

A self aligning bearing structure, especially adapted for electric motors, has an outer ring with a plastic jacket thereon. A housing for supporting a bearing has a cylindrical seat for receiving the outer ring. The plastic jacket has one annular central ridge of greater diameter, in the unassembled condition, than the seat, so that the annular ridge is compressed to substantially the compression limit when the outer ring is assembled in the seat. The plastic jacket may have a conical end to simplify assembly.
