The company didn’t have to look long to find the perfect partner, as Blickle has been a supplier of high-quality wheels and castors to other ROFA departments for years and came highly recommended. Working hand-in-hand with ROFA, the Rosenfeld-based wheel and castor specialists designed a specially tailored wheel - the GB 250x90/40. “Our team provided the customer with a number of different tread designs. Each underwent meticulous testing under real-world conditions at an automotive facility,” explains Thomas Zimmer, Head of Heavy Duty Wheels at Blickle. In consideration of the extreme conditions in play, Blickle’s experts optimised the tread geometry until the perfect solution was available.
The heavy duty wheels developed by Blickle have a tread made from the durable polyurethane Blickle Besthane, which is thicker than the standard versions in the company’s product range. This allows the wheel to handle any unevenness when transitioning between rails. The specially designed tread with a hardness of 96° Shore A provides a high level of rigidity and boosts the load capacity of the wheel so that it can handle heavy-duty loads weighing up to twelve tons. The polyurethane wheels also have a lower rolling resistance Blickle also incorporated two rows of high-quality angular contact ball bearings, which are capable of handling significant wheel loads without any issues.
