Our standard hubbed drive rollers are manufactured using a precision 303 stainless steel core. The bores are sized to fit undersize (nominal minus) precision ground shafting. Depending on part number, these drive rollers are supplied with either one or two stainless steel set screws so they can be securely fastened to a shaft. The urethane diameters are ground to tolerance of +/- .003" and maximum concentricity, relative to the bore, of .001"
