DR407A
 

DR407A is non-asbestos clutch facing which adopts refined glass fiber, imported composite fiber material with heat resistant properties, high grade copper to be composite yarns. And then added high-temperature resistance resin, imported anti-wear agents, lubricants, and high quality anti-wear and friction resistant regulating agents

This product has high mechanical strength, higher strength of violent anti-rotary, especially reflects stability in connecting and disconnecting, and stable friction coefficient, low wear rate, and perfect properties in wear and friction.
