BMT Series Disc Distribution Orbital Hydraulic Motor
BMT series is a low-speed high-torque orbital hydraulic motor with disc end distribution. Adopting 8/9 tooth pin-type geroler gear set and double tapered roller bearings, it is a general hydraulic drive component for medium & heavy load. Displacement ranges from 160 to 800 cc/rev. It performs well under high pressure with ultra-low starting pressure and sustainable high volumetric efficiency. It can directly drive working loads, widely applied in construction machinery, agricultural equipment, injection molding, mining, marine winch and other low-speed heavy-duty transmission fields. Customized versions including flange, output shaft, case drain, brake valve are available.

Core Advantages
- End Face Disc Distribution with Automatic Wear CompensationEquipped with high-precision distribution disc that automatically compensates internal clearance after abrasion. Volumetric efficiency stays above 90% for long-term operation. It runs smoothly without low-speed creeping, featuring low vibration and noise to extend service life.8/9-Tooth Pin Geroler Set Delivers Low-Speed High TorqueOptimized cycloid gear design realizes ultra-low startup pressure. Rated working pressure reaches 14 MPa, while intermittent peak pressure hits 21 MPa. It outputs powerful torque at low rotation speed to save energy and guarantee stable power output.Double Tapered Roller Bearings for Heavy Combined LoadsThe output shaft adopts double tapered roller bearings to bear large radial and axial composite loads. It can directly drive wheels, rollers and winches without extra reducers, simplifying the whole machine structure.Wide Speed Range & Compatibility with Various Hydraulic CircuitsStable operating speed ranges from 20 rpm to 300 rpm with seamless speed transition. It tolerates back pressure up to 10 MPa and supports series or parallel connection of multiple motors, fitting diverse complex hydraulic systems.Compact Integrated Housing with Universal Easy InstallationIntegral cast steel housing features small size and light weight. Standard 4-bolt square flange is equipped as default, with multiple optional ports and output shafts. It matches mainstream international mounting dimensions for convenient replacement.
Applications
- Widely applied to mini construction machinery, agricultural machinery, hydraulic winches, sanitation & garden equipment, mining conveyors, injection molding and light industrial machinery.
