Abstract
The specification discloses a roller conveyor having a plurality of elongated cylinders arranged to define a planar conveyor path. Each of the cylinders includes a low friction plastic bearing member rigidly mounted in the end thereof, with each of the bearing members including blind sockets formed in the centers. The cylinders are disposed between a pair of parallel side rails and a plurality of rigid metal shafts are connected along the interior sides of the rails. The ends of the shafts are received within the blind sockets in the bearing members such that the bearing members and cylinders rotate relative to the rigid metal shafts.
