Our steel sprockets form the most important link between the chain and drive. We supply standard sprockets with a unilaterally protruding hub, pre-bored or as a Taper version with a normal or double Taper. Certain sizes are also available as a taper version with hardened teeth. The sprocket is determined by the chain size, in other words the pitch and version (simplex, duplex or triplex) and the number of teeth. When designing the chain drive, make sure that there is an odd number of teeth and links. This causes the teeth to engage alternately, ensuring optimal wear on the roller chain and the sprocket.
