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.
