The AZMF-12-005USA20ML motor is part of the AZMF External Gear Motors series manufactured by Bosch Rexroth. It converts hydraulic pressure into rotation for automated equipment that needs stable flow delivery. A fixed displacement of 16 cm³ per revolution defines the volume moved each cycle, and a minimum speed of 500 rpm keeps internal lubrication effective. The motor endures up to 3000 rpm for short bursts and handles 230 bar system pressure for medium-pressure circuits. An 80 mm pilot diameter centers the casing, while M6 mounting hole threads hold it rigidly to the machine frame. These features combine to give installers predictable mounting geometry and flow output.
The square-flange port interface identified by code 20 streamlines line routing, and a separate M12×1.5 drain port releases case oil to minimize seal load. A 20 mm shaft with a 1:5 taper transfers torque without key stress concentrations, and NBR seals maintain a barrier against fluids up to 80 °C. The same seals tolerate ambient temperatures between −30 °C and 80 °C, supporting outdoor service. Oil viscosity must stay at or above 12 mm²/s to preserve hydrodynamic film strength. With a mass of 3.6 kg the unit can be installed by one technician, making it suitable for compact power packs and mobile hydraulic drives.
