Abstract
A cam follower adapted for use in connection with a turntable assembly includes a common support shaft having a longitudinal axis and first and second roller assemblies, each having an outer tire portion and an inner bearing portion. The outer tire portions have curved outer peripheries shaped as truncated spheres, spheroids or ellipsoids, are rotatable about the longitudinal axis independently of one another, and are formed from a polymer material, such as polyimide, polyaryletherketone (PAEK), acetal, cast nylon 12 or cast nylon 6. The outer tire portion of the first roller assembly is adapted to be positioned a first radial distance, and the outer tire portion of the second roller assembly is adapted to be positioned a second radial distance, from the axis of rotation of the turntable assembly, the second radial distance being different than the first radial distance.
