Abstract: A thrust washer includes an annular body with an aperture therein and having a first axial face and a second axial face, an outer diameter edge and an inner diameter edge extending between the first and second axial faces. At least one of the first and second axial faces includes a plurality of recessed grooves extending at least partially between the inner edge and the outer edge and defining un-recessed lands between the recessed grooves. The plurality of recessed grooves include a transition region transitioning to the lands and a scoop region separated from the transition region by a stepped wall portion extending between the scoop region and the tapered region. The recessed grooves can include directional symmetric bi-directional grooves for use in systems with rotation in both directions.

Abstract: A thrust washer includes an annular body with an aperture therein and having a first axial face and a second axial face, an outer diameter edge and an inner diameter edge extending between the first and second axial faces. At least one of the first and second axial or conical faces includes a plurality of recessed grooves extending at least partially between the inner edge and the outer edge and defining un-recessed lands between the recessed grooves. The plurality of recessed grooves defining an average groove width and the plurality of lands defining an average land width between the grooves, wherein a ratio of the groove width to the land width is in a range of 0.2 to 2. The plurality of recessed grooves include a convex lead in surface having a lead in radius.
