About Fuzhou Ultra

Fuzhou Ultra Precision Machinery is located in Jinan District, Fuzhou City, Fujian Province, China, with over 20 years of experience in the production of cam & groove couplings, valves, and other OEM component manufacturing.

Our customer base includes marine and oil exploration companies, bulk transporters, bunkering vessel owners, and industrial fluid handling operations across the globe.

Engineering Excellence

We design our couplings to match working machine load characteristics. Constant torque machines use torque-limiting cam and groove couplings, while parabolic load applications benefit from multi-speed hydraulic transfer systems.
