TMT OMT TMTU TMTW Series Hydraulic Orbit Motor OVERVIEW

TMT, OMT, TMTU and TMTW orbit motors are low-speed high-torque hydraulic gerotor motors, engineered for reliable heavy-load drive. With advanced geroller gear design, they deliver high starting torque and smooth steady rotation at ultra-low speeds. Compact integrated structure cuts installation space while bearing heavy radial & axial shaft loads. Multiple displacement, shaft, port and brake versions are available to match diverse working demands, widely adopted in agricultural, construction, forestry and sanitation machinery.

Features and Benefits

• Optimized geroller stator-rotor pair, low internal leakage, high volumetric efficiency

• Large startup torque, stable operation without creeping at low rotation

• Reinforced output shaft, strong resistance to impact and side load

• Broad pressure range, peak intermittent pressure reaches 350 bar

• Compact monolithic housing, easy mounting and maintenance

• Optional built-in multi-disc brake for load holding and safety stop

• Various oil port layouts and shaft types for direct equipment replacement
