Cross+Morse can provide a full range of HV and SC Sprockets manufactured in the best combination of materials and heat treatment to ensure long service life with ability to transmit full designed torques and powers with minimum noise and vibration
HC/SC Sprockets
Sprockets up to 30 teeth and below are usually manufactured from low carbon alloy steels with teeth carburised and sprockets hardened to provide maximum wear resistance with high core strength, larger sprockets are produced in medium carbon steel with induction hardened teeth, or meehanite castings. It is recommended that a minimum 25 tooth sprockets be used in all drives to provide best efficiency, smooth transmission and low noise levels, however, all sizes of chain can operate on sprockets down to 19 teeth, but such drive designs should always be referred to Cross+Morse. It is preferred practice to use sprockets with odd numbers of teeth, but for 1:1 ratio even teeth sprockets should always be used for optimum chain life and performance.
