Реферат: A thrust ring (30) for an undercarriage (10) in a track-type machine includes an annular body (32) having an outer circular edge (34) and an inner circular edge (36) defining a common center axis. A first set of oil grooves (46) and a first set of thrust faces (48) are positioned in an alternating arrangement on each of a first axial side (40) and a second axial side (44) of the annular body (32). Each of the oil grooves (46, 50) includes a cross sectional contour shaped to balance an oil flow property of the thrust ring (30) with a strength property of the thrust ring (30), and defining a non-uniform curve which includes a plurality of curve segments each having a different radial attribute. The thrust ring (30) defines a Plouzek value equal to 1.
