Low Speed High Torque Nhm (S) 6 External Five Star Radial Piston Hydraulic Motor

The NHM(S)6 external five star motor features an externally positioned five-star stator and reinforced crankshaft, delivering 30% higher torque density and better heat dissipation than inner five star models, making it ideal for heavy-duty applications requiring maximum power in a compact footprint.

Yes, the NHM(S)6 is engineered for continuous high-pressure operation up to 31.5 MPa (4570 PSI) with peak ratings of 35 MPa, maintaining stable low speed high torque output without efficiency drop, perfect for winches, cranes, and mining equipment under extreme loads.

Absolutely. The NHM(S)6 offers standard external spline shaft options (DIN 5480/ISO 4156) for direct coupling to gearboxes or drums, eliminating intermediate adapters and reducing backlash in marine winch drives, conveyor systems, and plastic injection molding machines.

Yes, reversible rotation is factory-standard on all NHM(S)6 units, enabling seamless bidirectional operation in hydraulic systems for deck cranes, anchor winches, and mobile machinery without additional valves or complex piping modifications.

With its reinforced roller bearings and optimized valve plate timing, this heavy-duty hydraulic motor withstands continuous shock loads and thermal cycling in steel mills, rubber mixers, and offshore platforms, ensuring 20,000+ hour service life under harsh industrial conditions.
