The AZMF-10-022RSA20MB external gear motor belongs to the AZMF External Gear Motors series from Bosch Rexroth and is intended to convert hydraulic energy into rotary motion for automation systems. It provides a displacement of 22.5 cm³ per revolution to establish circuit flow, and it is configured for right-hand rotation. Maximum operating pressure is 160 bar, allowing the housing and gears to withstand medium-duty loads. The drive interface is a 1:5 tapered keyed shaft, the key follows DIN 6888 4 × 6.5 dimensions, the shaft end diameter measures 20 mm, and an M12 × 1.5 thread seats the retaining nut. An Ø80 outboard bearing is integrated into the front cover (Type 1) so radial belt or gear forces can be supported without external supports.
The motor runs between 500 and 2500 rev/min to accommodate variable-speed machine cycles. Mineral-oil hydraulic fluid is required, and the fluid may reach 80 °C while the surrounding ambient may also rise to 80 °C without impairing service life. All dynamic sealing elements are made from NBR to resist the specified fluid and temperature limits. A rectangular flange forms the pressure and return ports, streamlining rigid pipe installation, while a standard rear cover completes the enclosure without add-ons. Total weight is 4.8 kg, which keeps the unit light enough for compact mobile or stationary assemblies.
