Description: the polyurethane coupling, rubber coupling are made by injection with high quality TPU material or mould CSM/SBR. It is designing and special for all kinds of metal shaft coupling with very good performance of high tensile strength, high wear resistant, high elastic resilience, water resistant, oil resistant and excellent fatigue resilience, high impact resistant etc. We have full sets moulds and supply full range of GR, GS, MT, ML, MH, Hb, HRC, L, T, NM and Gear J series couplings etc. with high quality and excellent experience. Apply to all kinds of industrial metal shaft coupling.
