A roller assembly (32) for a ground-engaging track system (24) includes a roller (34) forming a shaft bore (42), and a roller shaft (52) within the shaft bore (42) and having a circumferential ramp surface (60). A roller retention system (83) for the roller assembly (32) includes a roller retention collar (84) with an outer peripheral surface (96), and an inner peripheral surface (98) that may include a wedge surface (98) structured to friction fit the retention collar (84), within a collar bore (44) in the roller (34), upon the circumferential ramp surface (60) to limit axial displacement of the roller (34) upon the roller shaft (52). The roller assembly (32) may include two roller retention collars (84,86) supporting the roller (34) against axial displacement without use of thrust washers or the like, and fixing the roller (34) and roller shaft (52) to rotate together relative to a track roller frame (26).
