NHC/NHF series hydraulic couplings are NGC’s newly developed keyless couplings which are mounted by using the way of hydraulic pressure. NHF series are flange-type hydraulic couplings, and NHC series are sleeve-type hydraulic couplings.

NCP series CPP are widely used as the main propulsion devices in inland vessels, offshore mixed ships, working boats, fishing boats, pelagic vessels and war ships. NGC is able to design and produce 400 sets of CPP per year.

Technical properties：
◆ Assembly/disassembly through hydraulic pressure, which does not need shrink fit..
◆ Easy to operate, time saving
◆ Keyless connection, no stress concentration
◆ Applying of intermediate bushing makes the shaft machining easier.
◆ Strength of components meet the requirements of every Classification 
    Society
◆ Torque tests are carried out on products of each series, high safety and reliability
◆ Easy to change.

Application：
◆ Mainly apply to the connection of marine propeller shafting
◆ Widely used in applications where high torque and fast assembly are needed
◆ Two series of these coupling are available for selection per actual demands.
