Product Description
NHM Low-Speed High-Torque Hydraulic Piston Motors
NHM Low-Speed High-Torque Hydraulic Piston Motor is a radial crankshaft connecting rod type Hydraulic piston motor, which is a widely adopted heavy-duty hydraulic motor. As the key executing component of the hydraulic system, it converts hydraulic pressure energy into powerful low-speed rotary torque to drive all types of Machine. This Hydraulic piston motor adopts five-star radial piston structure, featuring huge starting torque, stable low-speed running and high volumetric efficiency. Driven by pressurized oil supplied from hydraulic pump, it delivers reliable rotary power for heavy-load equipment. We also provide matching overhaul repair kits and spare parts for maintenance of this hydraulic motor.
Key Features
✅ Five-piston eccentric crankshaft structure, low vibration and low noise. The hydraulic motor maintains smooth rotation even at extremely low speed, ensuring stable performance of the whole hydraulic system under heavy impact load.
✅ Adopts plane compensation oil distribution plate design, low internal leakage and high volumetric efficiency. Excellent wear resistance enables long-time continuous operation of heavy-duty Machine in tough working sites.
✅ Large starting torque, no crawling phenomenon at low speed. Multiple displacement options and various shaft / flange configurations for flexible installation on different Machine.
✅ Compact and robust cast housing, strong pressure resistance. This Hydraulic piston motor can directly drive heavy loads without additional speed reducer in many hydraulic system designs.
✅ Strict pressure and performance testing before shipment. Original replacement and domestic alternative versions are available, related spare parts in stock.
Application
This Hydraulic piston motor acts as the core drive unit for heavy-duty Machine. Widely applied in hydraulic winches, crawler travel assemblies, injection molding machines, mining machinery, deck marine equipment, metallurgical machinery and drilling rigs. Within the hydraulic system, the hydraulic motor receives pressurized oil flow and outputs massive torque, perfectly suitable for low-speed high-torque working conditions.
