AZMF-12-014UQR12ML SO468

The AZMF-12-014UQR12ML SO468 hydraulic motor belongs to the AZMF External Gear Motors series produced by Bosch Rexroth. It converts hydraulic energy into mechanical motion for mobile and industrial automation tasks that need compact external-gear units. The motor provides a displacement of 14.0 cm³ per revolution, so each shaft turn moves a fixed fluid volume that determines output torque. Its universal direction of rotation allows the shaft to be driven clockwise or counter-clockwise, making installation easier in circuits that reverse flow. Continuous service is possible from 500 min⁻¹ up to 3000 min⁻¹; the lower limit prevents inadequate lubrication at slow speeds, and the upper limit defines the point where bearing loading and fluid shear remain within safe limits. These speed boundaries allow designers to match pump flow to desired actuator velocity without exceeding mechanical limits.

Bosch Rexroth specifies mineral oil–based fluids that meet DIN/ISO standards for this motor, ensuring the gear teeth receive proper lubrication viscosity and additive chemistry. An NBR shaft seal is fitted, and this nitrile material is selected for resistance to petroleum oils and moderate heat. The same seal compound sets maximum ambient and fluid temperatures at 80 °C, which protects elastomer integrity during continuous duty near hot power units. When fluid or housing temperatures remain within that ceiling, volumetric efficiency and seal life are maintained. A drain oil line is routed axially through the rear cover, allowing case leakage to be directed back to tank and preventing pressure buildup behind the shaft seal. Together, these design limits and fittings support reliable service in hydraulic circuits that operate for long periods under variable thermal loads.
