Abstract: Components for roller assemblies including a cylindrical roller pipe, and first and second end members having internal roller bearings, the end members being slidable onto a fixed cylindrical axle and into the ends of the pipe. Hubs on the end members frictionally engage the inside of the pipe, and a flange abuts the end of the pipe. A plurality of hollow frustoconical members are slidable over the pipe in end-to-end relationship surrounding the pipe between the end members, the outer surfaces of the frustoconical members making equal angles with the axes thereof, the members being of graduated sizes so that the smaller end of one member has an outer surface diameter equal to the larger end of the next adjacent member to form a continuous frustoconical outer surface along the length of the assembly. An annular spacer is provided between the outside of one end of the pipe and the larger end of the largest one of the frustoconical members to maintain proper coaxial spacing of the larger end, the spacer member having a shoulder abutting the larger end of the largest member. One of the end members can have a pulley for driving the roller assembly.
