Our standard idler rollers are manufactured using oil impregnated 841 sintered bronze sleeve bearings. They are designed for light duty applications with moderate to low speeds. The bearing bores are sized to fit undersize (nominal minus) precision ground shafting as well as some oversize (nominal plus) precision ground shafting. We bond the urethane directly to the sintered bronze which provides for a fairly low cost idler roller design. The urethane diameters are ground to tolerance of +/- .003" and maximum concentricity, relative to the bore, of .002".
