Abstract
A freerunning roller for use in a roller conveyor system comprises a cylindrical tube having saw cut ends providing a rough edge on each end which is relied upon to effect frictional interengagement with a relatively soft plastic cup dimensioned for force fitting into the tube and also dimensioned internally to receive a ball bearing in force fitted relation. The bearing assembly is completed by a bushing which is force fitted into the bearing and also has a hexagonal bore for receiving a hexagonal shaft by which the roller is mounted in a conveyor frame.
