Power Transmission Couplings

We supply a full range of flexible and rigid couplings including serpentine spring grid, crown‑gear, universal and custom machined couplings. Made of 45# steel, 40Cr and 42CrMo alloy steel via CNC turning, hobbing, heat treatment and dynamic balancing. Precision bore H7 and key‑way JS9 are available to compensate shaft misalignment, damp shock and transfer torque reliably. Surface options cover black oxide, phosphating and powder coating. Widely applied for pumps, fans, reducers, conveyors, agricultural and construction machinery. Custom sizes and OEM service are supported.
