High performance and long-lasting, the Rexroth A2FE Axial Piston Fixed Motor - Series 70 is made specifically for mobile and industrial applications. These motors are designed for hydrostatic drives in both open and closed circuits, comes with fixed displacement and bent-axis construction. Their small size makes it possible to put them in confined spaces. Even in the most demanding conditions, their high power density guarantees dependable and seamless performance.

Rexroth A2FE motors are well known for their excellent starting efficiency, small size, great total efficiency, and high power density. They are readily integrated into various mechanical gear systems and are available in a broad range of sizes. The A2FMN and A2FEN series (sizes 28 to 107) are available in numerous series, with a nominal pressure of 300 bar and a maximum pressure of 350 bar. Nominal pressure for A2FMM, A2FEM (sizes 23 to 180) is 400 bar, and maximum pressure is 450 bar. Nominal pressure and maximum pressure for A2FMH, A2FEH (sizes 45 to 125) are 450 bar and 500 bar, respectively.

These motors comes with long service life and superior resistance to torsional vibrations add to its durability and low maintenance requirements. The motor's displacement and the pump's flow determine the output speed. The pressure difference between the high-pressure and low-pressure sides affects their output torque. Rexroth A2FE can rotate at very high rates, enabling smooth operation even in the most severe conditions.
