A thrust washer formed from metal sheet has a flat, ring-shaped thrust portion oriented radially, and at least one tab extending from an outer or inner perimeter of the thrust portion. 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 can engage a recess of a backup member to prevent rotation of the thrust washer relative to the backup member. The tab is not symmetrical about a line along a diameter of the thrust portion. |
