Abstract
A cam follower assembly having a plastic guide body and a cam follower having two opposing roller shaft ends is provided. The single piece guide body includes a pair of grooved members. Each of the grooved members include an interior surface defining an elongated guide groove having a recessed surface. The elongated guide grooves are facing and aligned with each other. The cam follower is disposed between the pair of grooved member such that one of the roller shaft ends is received in one guide groove and the opposite roller shaft end is received in the other of the guide groove. The roller shaft ends are slidable in a reciprocal axial direction within the elongated guide grooves and retained between the recessed surfaces. The plastic guide body may be injection molded from a nylon material having glass fibers.
