The MV037-A2-1S-032-31-B1-TBB-000 hydraulic motor is produced by Bosch Rexroth for the MV Rineer High Torque Vane Motors series and converts pressurized fluid into controlled rotation for automated machinery. It has a displacement of 32 in³ per revolution (524 cm³/rev), defining the flow required for a given speed. When supplied with a differential pressure of 3000 psi (207 bar) it delivers 1143 lb-ft (1550 Nm) of torque, supplying ample rotary force for heavy tooling. Continuous duty is permitted at 3000 psi and 1000 rpm so the unit can run for extended periods without overheating. Short transient demands can raise loading to 3500 psi (241 bar) and 1200 rpm, giving extra output during start-up or cycle peaks. The motor weighs 97 lb (44 kg), a factor to consider when selecting supporting brackets and foundations.
Mechanical integration is handled by an SAE J744 152-4 mounting flange coupled with a 6.000 in pilot diameter held within a –0.002 in tolerance to maintain concentricity with the driven shaft. Four 1/2-13 UNC bolts measuring 1.00 in seat the housing against the flange to resist vibration. Fluid lines attach to a 1-1/2 in four-bolt two-port flange, allowing straightforward connection to pressure and return hoses. Static joints in the main body and pedestal are sealed with NBR (Buna) O-rings to contain high-pressure oil. A TCN radial lip seal blocks leakage along the rotating shaft. Output torque is transferred through a 13-tooth spline cut to 8/16 DP with a 30° pressure angle, and the flat root side class 7 fit limits backlash while supporting full load.
