Rexroth A2FE Series High-Pressure Plug-in Fixed Motors

Product Overview: The Rexroth A2FE Series is the premier power solution for heavy-duty mobile machinery where installation space is at a premium. As a definitive Plug-in (Fixed Displacement) piston motor, its unique design features a mounting flange located in the center of the housing, allowing the motor to be largely “recessed” into planetary gearboxes. This featured selection covers the entire displacement range: A2FE55, A2FE80, A2FE107, A2FE125, and A2FE160. With a robust 400 Bar pressure rating, the A2FE is the benchmark for excavator travel drives, drilling rig propulsion, crawler undercarriages, and winch gearbox integration.

Key Technical Advantages:

• Extreme Space Savings: The plug-in architecture significantly reduces the axial length of the hydraulic drive unit, enabling a more compact machine layout—perfect for narrow-track wheel or crawler drives.

• Peak Pressure Resilience: Rated for continuous operation at 400 Bar (5800 PSI) with peak capabilities up to 450 Bar, ensuring ultimate stability during heavy-duty climbing or high-torque starts.

• Bent-Axis High Efficiency: Utilizing classic 45° bent-axis technology, it delivers elite power density and superior starting torque, minimizing energy losses.

• High Integration: Designed for a perfect fit with planetary reducers, reducing wear on couplings and lowering the overall maintenance cost of the system.

• Rugged Series 61W/63W Engineering: Features reinforced bearings and specialized sealing systems optimized for the vibrations, shocks, and harsh environments of construction sites.

• Target Applications: Crawler travel propulsion, rotary drilling rig power heads, integrated winch motors, concrete mixers, and hydrostatic transmissions.
