A tripot universal joint includes a first rotatable shaft member having a first longitudinal axis and three longitudinal guide channels disposed parallel to the first longitudinal axis, each having two opposing concave side surfaces and a back surface. The joint also includes a rotatable second shaft member having a second longitudinal axis and comprising a spider having three radially extending trunnions equally, each of the trunnions having a convex outer surface disposed within an associated longitudinal guide channel. The joint further includes three rotatable rollers, each rotatably disposed on a convex outer surface of a respective trunnion, each roller having a convex outer surface that is configured for disposition within the concave side surfaces of the longitudinal guide channel with which it is associated for moveable engagement within the channel and an inner surface that is rotatably disposed on the convex surface of the trunnion. |
