We can manufacture all range of friction disc of engineering machinery parts for JCB, Caterpillar, Komatsu, Hitachi, Sauer Danfoss, Bridge Stone.
The parts including all kinds of the friction disc and the steel mating plate, friction disc parts diameter range from 54mm to 1038mm. The friction disc material we can provide for engineering machinery including paper material, carbon graphite and ceramic copper. Our regular paper friction materials test property shows as follows:
9713-1999 PAPER BASED WET DISK FOR ENGINEERING MACHINERY. Non-asbestos paper based disk, material weight percentage:
Paper 30%~40%, Aramid Fiber 3%~7%, Glass Fiber 10~17%, Porcelain Clay 9%~15%, Aluminum Oxide 12%~15%, Graphite 8%~10%,Phenolic Resin 11%~16%.
Paper based friction disc is tested inside oil dipped clutch disc test machine, paper based friction disc wear rate: 1.39x10-5 mm3/J ~1.46x10-5mm3/J, paper based facing is suitable for low speed, high torque and high power transmission. The adhensive property of paper disk is tested by bending method.
Static coefficient of friction and dynamic coefficient of friction, both comply with the national standard of paper based wet disk for engineering machinery.
