Our standard hubbed urethane 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″. Please note: The –ZZ portion of the part number below refers to the hardness (durometer). For 55A use -55 and for 70A use -70.
