Rexroth A2F Series Fixed Displacement Bent Axis Pump & Motor Units

Product Overview: The Rexroth A2F Series is a quintessential bent-axis fixed displacement unit in the hydraulic industry. Due to its symmetrical mechanical design, this series can operate as both a Hydraulic Pump (for open circuits) and a Hydraulic Motor. Its classic bent-axis piston architecture ensures high starting torque efficiency as a motor and superior self-priming characteristics as a pump. This category features high-precision models: A2F28, A2F55, A2F63, A2F80, and A2F200. These units are the primary choice for construction machinery travel drives, crane winch systems, concrete pumping equipment, and metal recycling machinery.

Key Technical Advantages:

• Proven Durability: The fixed displacement design eliminates complex variable mechanisms, resulting in a robust structure with an exceptionally low failure rate.

• Superior Power Density: Delivers massive energy output within a compact envelope, ideal for heavy-duty machinery with limited installation space.

• High-Pressure Resilience: Rated for a continuous pressure of 350 Bar with peak capabilities reaching 400 Bar. Optimized spherical valve plates significantly reduce wear and extend service life.

• Versatile Shaft & Porting: Available in multiple configurations such as 2P3 (Keyed Shaft), 2Z2 (Splined Shaft), and 2PB (Reinforced Interface), ensuring a perfect match with various couplings and gearboxes.

• Target Applications: Road roller travel drives, excavator auxiliary systems, industrial hydraulic winches, and various hydrostatic transmissions.
