The Rexroth A2FE series is a line of fixed displacement axial piston motors with a bent-axis design. They are known for their high performance in open and closed circuit hydrostatic drive systems.

• High Power Density and Efficiency: They offer high power in a compact size, with high total efficiency leading to energy savings.
• Space-Saving Design: A central recessed mounting flange allows for direct integration into mechanical gearboxes, making them ideal for applications with strict space constraints.
• High Pressure Rating: The motors are built for high-pressure operation, with nominal pressures of up to 400 bar (for sizes 28-180) and peak pressures of up to 450 bar.
• Ready-to-Install: These units are supplied as complete, pre-assembled, and tested modules, requiring only to be "plugged" into the gearbox, which reduces installation time and complexity.
• Excellent Performance: They provide high torque output and smooth operation with low noise and vibration levels.

The A2FE series includes a wide range of models with different displacements to meet various power and speed requirements. Common models include:

• A2FE28 / A2FE32 / A2FE45
• A2FE56 / A2FE63 / A2FE80
• A2FE90 / A2FE107 / A2FE125
• A2FE160 / A2FE180 / A2FE250 / A2FE355

A2FE motors are versatile and used in a wide array of mobile and industrial machinery, such as:

• Construction machinery (e.g., excavators, mixers)
• Agricultural equipment
• Material handling and conveyor systems
• Metallurgical, mining, and marine equipment

Important usage considerations:

• Steering Direction: The standard rotation is clockwise (viewed from the shaft end). Counter-clockwise rotation must be specified when ordering.
• Initial Startup: Before the first start, the motor casing must be filled with clean hydraulic fluid through the drain port.
• Alignment: Ensure proper concentricity between the motor and the driven unit to avoid noise and reduced efficiency.
• Working Fluid: Use recommended hydraulic oils (e.g., ISO VG 46 or 68) and maintain fluid cleanliness to ensure long service life.

Some manufacturers and suppliers indicate that they can provide OEM services. This typically means that they can customize products, including applying the client's brand (OEM), often dependent on the order quantity.
