Series M motors come in four sizes, with standard or heavy-duty bearings for high-speed (to 4,000 rpm), high-pressure applications. The dual-alternative pressure plate provides overall efficiency of at least 86% and also allows reversing direction of oil flow. Inlet and outlet ports can be pressurized simultaneously without sacrificing service life or operating smoothness. Torque ratings range from 42 to 300 lb-in./100 psi.
