ABSTRACT:
An axial needle bearing assembly includes needles guided in a needle cage and located between thrust washers. The needles are distributed about the axis of the assembly and spaced angularly apart by the cage. The cross section of the thrust washers are L-shaped having nested legs surrounding the needles. One thrust washer has its leg inclined with respect to the legs of the other thrust washer and spaced apart defining a region in which lubricant is contained. At several angularly spaced locations, beads are formed on a leg of one of the thrust washers which overlap the other thrust washer and prevent disassembly but permit axial play between the thrust washers.
