The MV037-A2-1S-026-30-B1-TBB-000 motor belongs to the MV Rineer High Torque Vane Motors series manufactured by Bosch Rexroth for hydraulic automation where high startup torque and controlled speed are required. Its fixed displacement is 26 in³ per revolution, giving predictable flow and simplifying pump selection. The unit endures a continuous working pressure of 3000 psi (207 bar) and maintains a steady 800 rpm, ensuring stable performance in long-duty cycles. At that pressure differential the motor supplies 920 lb-ft (1247 Nm) of torque, making it suitable for heavy rotational loads. A B1 bearing arrangement supports the shaft under combined radial and axial forces to preserve alignment and service life.
The design allows brief overloads to 3500 psi (241 bar) and 1000 rpm, giving extra power for intermittent demands. Hydraulic ports follow the A2 option, providing a 1-1/2 inch four-bolt pattern with two pressure connections for straightforward plumbing. Installation aligns with an SAE J744 152-4 flange so the motor couples to industry-standard mounting pads. A TCN radial lip shaft seal guards against oil loss while tolerating up to 35 psig case pressure. NBR (Buna) O-rings at the main body and pedestal joints maintain sealing integrity, aided by a maximum fluid temperature limit of 180 °F (82 °C) to protect elastomers. The assembly weighs 97 lb (44 kg), balancing robustness with manageable handling during equipment service.
