Abstract
A thrust washer formed from metal sheet has a flat, ring-shaped thrust portion oriented radially, an axially oriented circumferential lip extending along one of the inner and the outer diameters of the thrust portion, and a tab extending from the circumferential lip. The tab includes a radially oriented mid-portion and at least one wing-portion extending perpendicular to the mid-portion and parallel to the axis of the thrust portion such that a flat surface of the wing-portion may engage a recess of a backup member to prevent rotation of the thrust washer relative to the backup member.
