Product Description
LIC Hydraulic presents the Rexroth A2FE Series, a high-performance fixed displacement bent axis axial piston motor. The featured model ALA2FE250/60W-VZM010 (R902418396) is a specialized Plug-in motor designed for seamless integration into mechanical gearboxes (such as planetary drives). This design significantly reduces the axial length of the drive unit, making it ideal for mobile track drives and winches. Engineered for high-pressure open and closed circuits up to 400 bar, our units offer 100% drop-in interchangeability with original Bosch Rexroth components. Every unit is 100% load-tested to ensure peak volumetric efficiency and reliability in extreme environments.

Key Technical Advantages
Superior Bent Axis Technology: The 40° bent axis geometry provides unmatched starting torque and mechanical efficiency. It outperforms swashplate motors in heavy-duty startup conditions and high-speed stability.
Space-Saving Plug-in Design: The A2FE housing is optimized to sit inside planetary gear reducers, eliminating unnecessary coupling length and simplifying drive-train architecture for tracked vehicles.
Spherical Valve Plate: The self-centering spherical valve plate maintains a perfect seal under high-pressure deflections, ensuring minimal internal leakage and maximum output power.
Reinforced Tapered Roller Bearings: Built to withstand high radial and axial forces, these bearings support continuous operation under severe shock loads, extending the service life in mining and construction apps.
Application Areas
Construction Machinery: Main travel drives for excavators, rotary drilling rigs, and asphalt pavers.
Lifting & Cranes: High-torque motor for primary and secondary winches in mobile or tower cranes.
Marine Applications: Heavy-duty anchor winches and deck machinery propulsion.
Tunneling (TBM): Cutter head drives and high-pressure pumping units.
Expert Maintenance Tips
Initial Priming: Before startup, the motor housing must be filled with clean hydraulic oil through the highest drain port. During plug-in installation, ensure the O-rings are correctly seated to prevent case-side leakage.
Case Drain Pressure: The drain line must lead directly back to the reservoir. Ensure the back pressure does not exceed 2 bar to prevent shaft seal blowout and efficiency loss.
Thermal Management: Given the high power density of the 250cc displacement, monitor oil temperatures closely. Maintain an ideal viscosity range ($16\text{–}36\text{ mm}^2\text{/s}$) to protect the precision-lapped piston surfaces.
