The idler or pulley includes a cylindrical chamber in each end for reception of bearing assemblies therein. Each of the bearing assemblies in each end of the idler or pulley has a stub shaft therein. An elongated member which is tubular, at least at each end thereof, is press fit onto the inner ends of each of the stub shafts whereby the length of the elongated member can be chosen depending upon the length of the idler or pulley, while at the same time identical standard bearing assemblies and stub shafts can be used for idler pulleys of various sizes.
