Rexroth A2FE Motor | A2FE125, A2FE160 | Plug-in Fixed Displacement Motor

Rexroth A2FE Series High-Pressure Plug-in Piston Motors

Product Overview: The Rexroth A2FE Series is a plug-in (cartridge design) hydraulic motor specifically engineered for heavy-duty machinery where installation space is at a premium. As a definitive Bent-Axis fixed displacement motor, it is designed to be mounted directly into mechanical gearboxes, significantly reducing the overall axial footprint. This featured selection includes: A2FE125/61W-VAL100, A2FE160/61W-VZL100, and A2FE160/61W-NZL100. The A2FE series is the premier choice for excavator travel drives, crawler propulsion, rotary drilling rig gearboxes, and industrial drive units.

Key Technical Advantages:

• Maximum Space Efficiency: The plug-in flange design allows the majority of the motor to be embedded within the gearbox, making it the ideal choice for narrow-track machines and integrated drive systems.

• Peak Pressure Resilience: Rated for continuous operation at 400 Bar (5800 PSI) with peak pressures reaching 450 Bar, ensuring stability under extreme load cycles.

• Bent-Axis Efficiency: The optimized bent-axis piston design boosts volumetric efficiency and ensures consistent torque output even at high rotational speeds.

• Installation Versatility: The Series 61 is optimized for compatibility with various shaft and seal configurations (VZL, VAL, NZL), adapting to different hydraulic fluids and sealing requirements.

• Rugged Construction: Built for the harsh environments of construction machinery, offering superior resistance to vibration and mechanical shock.

• Target Applications: Crane winch drives, mobile machinery travel systems, mixer drives, and various hydrostatic transmission circuits.
