Abstract
A caster roller unit for a freight conveyor track includes first and second support rollers to support the freight articles from below. The rollers are mounted on a roller carrier rotatably independently of each other about horizontally extending, mutually aligned axes. The roller carrier is supported on a stationary housing base member by a ball bearing assembly rotatably about a vertical axis which is eccentric with respect to the axis of the rollers. The roller carrier, for each of the support rollers, has an upwardly open bearing shell member in the form of a cylinder portion accommodating a plurality of bearing needles on which the respective support roller is rotatably disposed and the longitudinal axes of which are oriented parallel to the horizontally extending axis of rotation of the respective support roller. A housing cover member fixedly connected to the roller carrier embraces the support rollers from above to retain the support rollers and the bearing needles in the bearing shell member, with the support rollers projecting upwardly beyond the upper outward surface of the housing cover member.
