41 polyurethane // profile Polyurethane wheels for medium- to heavy-duty requirements areas of use// floors The material polyurethane (PU) has a high load capacity with low abrasion. It also features high chemical resistance. These properties make polyurethane suitable for almost any application. Properties high load capacity without leaving a mark or trace low abrasion impact-resistant low rolling resistance excellent chemical resistance resistant to oil and grease resistant to cutting by metal chips Shore hardness approx. 50° Shore A up to approx. 98° Shore A Temperature range polyurethane can be used from -20° C to +80° C the load-carry capacity is reduced at temperatures above +30° C Bearing types plain bearing (through hole) ball bearing precision bore and keyway groove uneven & loose solid & sensitive solid & smooth/ at solid & un- even/rough soft & sensitive
