AA2FM56/61W-VBD510

The AA2FM56/61W-VBD510 hydraulic motor belongs to the A2FM Fixed Motors series and is manufactured by Bosch Rexroth for use in hydraulic automation where constant-displacement drives are required. Its displacement of 56.6 cm³ per revolution determines the volume of fluid moved per shaft turn and sets the basic flow rate. A rated speed of 5000 rpm supports high-speed transmission stages without exceeding mechanical limits, and at that speed the inlet flow reaches 283 l/min, guiding line sizing for proper delivery. Continuous service is maintained at a nominal pressure of 400 bar, while a maximum pressure capacity of 450 bar permits brief overloads during load peaks. When operated at 400 bar the shaft produces 360 Nm of torque, converting hydraulic energy into rotary motion for downstream equipment. Bidirectional rotation allows the same unit to function in forward or reverse, simplifying circuit design in mobile and industrial machines.

A case pressure peak of 10 bar governs drain plumbing so housing back-pressure stays within seal limits, and a continuous case differential of 2 bar sustains internal lubrication without overstressing components. The case volume of 0.6 l provides room for oil circulation and aids heat dissipation. With a mass of 17 kg, mounting brackets must support both static and dynamic loads. The flange follows ISO 3019-2, allowing direct attachment to standardized pump pads, and pressure ports use metric threads compliant with DIN 3852 so common fittings can be applied. FKM sealing material resists high fluid temperatures and aggressive additives, extending service intervals. A summation pressure rating of 700 bar defines the allowable combined load across the high- and low-pressure sides in complex circuits, completing the set of parameters that govern safe integration of this fixed displacement motor.
