MOTORS AND ACCESSORIES
• The performance values listed below are for continuous use conditions. See the drawing for performance curves, including peak and intermittent values. • The optimal operating condition is 1/3 to 2/3 of the continuous use values. • Standard rotation is clockwise (facing the shaft) when port A is pressurized. • Standard shaft seals for the BM1 Series are rated to 1,085 PSI. HPSS to 2900 PSI. • Case drains relieve internal oil leakage and prevent housing overpressure, protecting seals and extending motor life. • Standard shaft seals and bearings are not recommended for applications that may experience side-loadings. • Internal check valves are included for smoother directional control. The BM1’s compact spool and gerolor gearset design delivers high power in a small volume and at a low weight. Easily and smoothly control the shaft rotation and speed. This motor achieves optimal efficiency and economy for medium load applications. Low Speed High-Torque Motors - BM1 Series Performance: • Radial Shaft Load: 440 lbs. (200 kg); 881 lbs. (400 kg) with radial bearing • Axial Shaft Load: 330 lbs. (150 kg); 440 lbs. (200 kg) with radial bearing • Ratings: 1,085 PSI standard, 2900 PSI HPSS; 15 GPM Max • Rotation: Bi-rotational, clockwise preferred • Temperature Rating: 100-120°F working, 176°F (80°C) max • Port Configuration: Parallel • Case Drain: SAE 4 Specifications:
