The MFB10-UY-31 hydraulic motor belongs to the Hydraulic Motors series manufactured by Vickers and converts pressurized fluid into rotary motion for automated machinery. Its theoretical displacement of 21.12 cm³ per revolution determines how much fluid is required to achieve a given speed. A rated flow of 37.9 L/min at 1800 r/min matches common pump outputs, while the rated operating speed of 1800 r/min supports continuous duty and the 3200 r/min maximum permits short-term high-speed cycles. Continuous operation is supported at 100 bar, and the 210 bar maximum pressure sets the upper limit for momentary load spikes. Bidirectional rotation lets the motor drive mechanisms in either direction without re-plumbing. Case pressure must stay below 0.35 bar to prevent seal damage and avoid oil leakage.
The motor delivers a maximum output torque of 64.2 Nm for breakaway conditions, and a rated torque of 32.1 Nm for steady loads. A shaft diameter of 22.22/22.20 mm and a 6.35 mm key allow secure power transmission to standard couplings. The 120.6 mm mounting bolt circle and 9.5 mm bolt holes position the housing on common hydraulic motor flanges, while the 101.60/101.55 mm pilot diameter keeps the motor concentric with the driven component. Dry weight is 9.5 kg, so support brackets and hoses can be selected accordingly.
