Mian Gear Motor Series
Hydraulic Gear Motors Built For Long-term Drive Reliability
Internal Protection of Oil Drive
Pressurized oil drives the internal gears, while proper filtration helps protect gear surfaces, bearings, and motor clearances.
Stable Power Transmission
The gear motor provides stable rotary motion for fan drives, conveyors, spreaders, and auxiliary systems.
Wear-Resistant Gear Contact
Optimized gear contact and stable internal clearances help reduce wear during continuous rotary operation.
Shaft Seal Protection
Proper back-pressure control helps reduce shaft seal stress and external leakage risk.
Factory Inspection Control
Production inspection helps verify hydraulic gear motor quality, model consistency, and shipment readiness before delivery.
Applications in Various Industries
Construction Machinery
Product Solutions: SDH-PH hydraulic motors adopt reinforced housing and enhanced sealing for shock and dust resistance. With universal mounting dimensions, it supports direct OEM replacement to reduce procurement and maintenance costs.
Agricultural Equipment
Fix farm operation defects such as low-speed jitter, insufficient torque and overheating. Stable output for long-hour heavy-duty farming.
Mining Machinery
Built-in oil circuit protection against dust and humidity. Reduce internal wear, adapt to harsh underground working conditions.
Common Problems of Hydraulic Gear Motors
Confirm working pressure, speed, mounting size and shaft diameter to match your hydraulic system flow.
SDH-PH hydraulic motors feature universal mounting dimensions for direct OEM replacement of European & American imported motors without pipeline refitting.
Air intake, contaminated hydraulic oil or insufficient system pressure will cause jitter and low power output.
Oil leakage mainly results from worn shaft seals and excessive back pressure. Upgrade reinforced seals and optimize system back pressure.
Low-temperature hydraulic oil has high viscosity. Run the motor with no-load preheating before formal operation.
Provide system pressure, oil flow, mounting flange and working conditions, we offer free professional model matching service.
Output torque depends on system pressure. Worn motors with heavy internal leakage will lose effective torque.
Unauthorized disassembly is not advised. Improper assembly will increase internal leakage and void product warranty.
Eccentric transmission, excessive radial impact and overload will fracture the shaft. Use elastic couplings and control rated load.
