Transmission Range-Control Module Output Shaft Bearing

This injection molded PTFE-filled PEI resin bearing replaces powdered metal, which offered limited parts integration and drove the use of additional parts and retention processes.  The new design has 3 lobed locking features for bearing retention and integrated locating posts. The ID is the shaft bearing and the OD is the spring driver bearing. Despite design complexity, the part is molded without tooling action.  PEI's moldability, stiffness, and lubricity were key to its selection. The part reduces mass by 45% and cost by 50% vs. the previous metallic part.
