The AZMF-11-011RCB20MB motor is produced by Bosch Rexroth within the AZMF External Gear Motors series. It serves as a compact pressure source for hydraulic automation circuits where a fixed displacement unit is required. The displacement is 11.0 cm³ for every revolution, setting the volume flow rate available to actuators. A right-hand rotation allows direct coupling to engines or electric drives that turn clockwise. Continuous operation is supported between 500 min⁻¹ and 3500 min⁻¹, so designers can match flow output to varying prime mover speeds. The maximum operating pressure is 210 bar, which defines the highest system pressure the housing and gear set can withstand. A shaft diameter of 17 mm provides the mechanical interface for torque transmission without requiring an adapter. The assembly weighs 3.0 kg, enabling installation on lightweight power units or mobile frames.
The motor includes an M12 × 1.5 drain connection that lets case leakage return to tank, preventing pressure buildup behind the shaft seal. A square flange front cover with an 80 mm centering diameter aligns the housing precisely on pump supports, while a rectangular flange port pattern labeled Type 20 creates standard suction and pressure connections. A standard rear cover is fitted, eliminating the need for special adapters on the back side. NBR is used for the seal material, giving compatibility with common hydraulic oils while containing costs. The unit can tolerate ambient temperatures up to +80 °C and keeps reliable sealing at fluid temperatures up to +80 °C, so it operates in warm engine bays or outdoor enclosures without additional cooling measures.
