Abstract
A thrust ring for an undercarriage in a track-type machine includes an annular body having an outer circular edge and an inner circular edge defining a common center axis. A first set of oil grooves and a first set of thrust faces are positioned in an alternating arrangement on each of a first axial side and a second axial side of the annular body. Each of the oil grooves includes a cross sectional contour shaped to balance an oil flow property of the thrust ring with a strength property of the thrust ring, and defining a non-uniform curve which includes a plurality of curve segments each having a different radial attribute. The thrust ring defines a Plouzek value equal to 1.
