Rexroth A2FE Series High-Pressure Plug-in Fixed Motors

Product Overview: The Rexroth A2FE Series is a premier power solution specifically engineered for compact hydraulic drive systems. As a definitive Plug-in (Fixed Displacement) piston motor, its unique architecture allows the motor to be largely recessed into planetary gearboxes, significantly reducing the overall axial length of the drive unit. This featured selection covers the essential displacement range: A2FE28, A2FE32, A2FE45, A2FE56, A2FE63, and A2FE107. With a robust 400 Bar pressure rating, the A2FE is the benchmark for excavator travel drives, crawler undercarriages, rotary drilling rig power heads, winch gearbox integration, and hydrostatic transmissions.

Key Technical Advantages:

• Extreme Compactness: The mid-housing mounting flange enables deep integration into mechanical gearboxes, making it ideal for space-constrained wheel or crawler drive systems.

• 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 startups and extreme gradeability.

• High-Efficiency Bent-Axis Design: The classic 45° bent-axis technology delivers elite power density and superior starting torque, minimizing internal energy loss.

• High Integration Capability: Designed for a perfect fit with planetary reducers, eliminating extra couplings and reducing both system weight and maintenance complexity.

• Rugged Series 61W Engineering: Features reinforced bearings and specialized sealing systems optimized for high-frequency vibrations and shocks in construction and mining environments.

• Target Applications: Crawler travel propulsion, drilling rig power drives, integrated winch motors, and concrete machinery.
