It is planning and unique for all kinds of metallic shaft coupling with really great performance of substantial tensile toughness, high put on resistant, substantial elastic resilience, drinking water resistant, oil resistant and exceptional exhaustion resilience, substantial affect resistant and many others. We have complete sets injection moulds and supply complete range of GR, GS, MT, ML, MH, Hb, HRC, L, T, NM and Gear J collection couplings etc. with higher high quality and exceptional expertise. Implement to all kinds of industrial steel shaft coupling.We are maker, engineer experienced abundant knowledge in excess of 20 many years. We manufacture higher high quality common joints for different vehicles, building machinery and gear. All items are built with rotating lighter.
