This invention relates to a roller and more particularly, but not exclusively to a conveyor idler roller. The invention also relates to a method of manufacturing a conveyor idler roller, and more particularly, but not exclusively, to a method of manufacturing a nylon or engineering plastic conveyor idler. The method includes the steps of providing at least two cylindrical shell elements made of a synthetic material, the shell elements having complementary profiled ends in order for the ends to mate when the shell elements are located end-to-end adjacent one another; and securing the cylindrical elements to one another by way of a friction welding process in order to form a composite shell. |
