page 4 / 16 General Wheels are machine-components with load bearing function. When selecting wheels and their material quality, a broad variety of options is available. Our production portfolio includes separate wheels of diameter 15 to 1000 mm as well as complete wheel assemblies similar to DIN, as per customer drawing or as design proposal approved by our customer. SIBE standard wheels are made of forged cylinders of material 42CrMo4V. For particularly high demands the wheels can be deep-hardened for reduced tread-wear.
