Surface Treated Roller Chain
Surface treatment has been made on the standard steel chain to improve its aesthetics and add corrosion-resistance. Please select appropriate surface-treated chains for your applications requiring environment resistance.
Rustop (N): All parts are plated with special nickel.
DC coat (DC): The surface is treated with baked special film. Its color is mat silver white.
BC coat (BC): All parts have undergone a special mechanical surface treatment. Its color is mat dark gray. Meets RoHS directive.
DG coat (DG): All parts are treated with special coat and top coat. Meets RoHS directive.
