German Rexroth A2FO160 Quantitative Hydraulic Motor with 315 bar Maximum Pressure Bent-Axis Design for Marine Applications

The Rexroth A2FO series is a line of fixed displacement, axial piston units with a bent-axis design. They are designed for use as a pump or a motor in open or closed hydrostatic circuits.

• High Pressure Rating: They offer high operating pressures, with certain models capable of a nominal pressure of 400 bar and a peak pressure of 450 bar
• High Power Density: The pumps feature a compact design, providing high power in a relatively small size
• High Overall Efficiency: They are designed for high volumetric and mechanical efficiency, contributing to energy savings
• Robust Construction: Key components include a high-strength nodular cast iron housing, highly load-capacity DU bearings, and floating side plates
• Excellent Starting Characteristics: They are engineered for good performance even at startup
• Versatility: The standard quantitative pump is suitable for a wide range of applications

Yes. The A2FO series axial piston element can function as a hydraulic motor in a hydrostatic transmission. When operating as a motor:

• The output speed is proportional to the flow rate and inversely proportional to its displacement
• The output torque increases with the pressure difference between the high-pressure and low-pressure sides

A2FO pumps are widely used in the hydraulic systems of various mobile and industrial machinery, including but not limited to:

• Engineering Machinery: Concrete pump trucks (boom pumps), cranes, excavators, mining machinery
• Construction and Transportation Machinery: Mixer trucks, lifting and transport machinery
• Industrial Applications: Metal forming, plastics, steel plants, mining, oil and gas, wind power

The A2FO series includes a wide range of models with different displacements. Some frequently mentioned models include:

• A2FO23/61L-PPB06
• A2FO32/61L-PAB05
• A2FO63/61R-PBB05
• A2FO80/61R-VPB05
• A2FO160/61R-PBB05

The series covers sizes from 5 to 1000.
