Abstract: A zero distortion bearing pulley including a bearing is provided. The bearing clamps axially on the outer bearing raceway instead of radially. The pulley includes a stamped pulley body having a central axis, a pulley face having a periphery, a belt running surface extending perpendicularly from the periphery of the pulley face, a bearing slip pocket formed in the face coaxially with the axis of the pulley body, and a plurality of slots formed between the bearing pocket and the periphery of the pulley face. The slip pocket has a rear stop for retaining the bearing. A disc-shaped, stamped bearing retainer is provided having tabs that fit into the slots in the pulley body. The tabs may be folded over. Optionally, each tab may have an end hook allowing attachment of the stamped retainer bearing to the pulley body face by rotation following insertion of the tabs into the slots.
