Cast iron forms the heart of all drive wheels. Most drive wheels are separable to facilitate assembly and replacement. The wheel halves form matching pairs and must not be mixed. Our drive wheels are supplied drilled and keyed according to your specifications and, depending on requirements, the type and size of the keyways are cut according to German DIN (metric) or customs standards. The friction drive types FR, FRD and KW can be used with any belt type and pitch.
