Rexroth A2FM Series Bent-Axis Fixed Displacement Piston Motors

Product Overview: The Rexroth A2FM Series is the industry standard for fixed-displacement actuators in industrial and mobile machinery. Featuring the classic Bent-Axis design, the A2FM axial piston motor delivers exceptional mechanical and volumetric efficiency in both open and closed circuits. This featured selection includes four core configurations: the compact A2FM12/61W-VBB030 and A2FM16/61W-VBB030, and the mainstream powerhouses A2FM45/61W-VZB010 and A2FM80/61W-VZB020. Renowned for its compact dimensions and superior speed ratings, the A2FM is widely utilized in mower drives, shredders, fan drive units, crane winches, and auxiliary travel systems.

Key Technical Advantages:

• High-Efficiency Bent-Axis Design: The unique bent-axis architecture allows for larger swivel angles, ensuring high power density and excellent startup torque even at maximum operating pressures.

• Fixed Displacement Precision: With displacement fixed by internal geometry, output speed remains strictly proportional to input flow, enabling precise and predictable velocity control.

• Heavy-Duty Duty Cycles: Rated for a nominal pressure of 400 Bar with peak capabilities reaching 450 Bar, handling heavy loads and frequent start-stop cycles with ease.

• Series 61/63 Optimization: The Series 61 features upgraded rotary groups and valve plate designs, significantly reducing noise levels and extending bearing life.

• Versatile Shafts & Connections (VZB/VBB): Offers a variety of standard keyed or splined shaft options and specific sealing configurations to ensure seamless integration and zero leakage.

• Target Applications: Road roller vibration motors, skid steer loader auxiliary drives, industrial press heads, and offshore winches.
