Rexroth A2F Series Fixed Displacement Axial Piston Pumps & Motors

Product Overview: The Rexroth A2F Series is a classic bent-axis fixed displacement unit designed to operate both as a hydraulic pump and a hydraulic motor. Renowned for its compact structure, high power-to-weight ratio, and exceptional stability under extreme high-pressure conditions, the A2F is a cornerstone of modern hydraulics. This selection features core high-performance specifications: A2F45, A2F55, A2F56, and A2F63, including specific models such as A2F45W61PA3 and A2F63R2P3. Capable of delivering consistent flow or torque at peak pressures up to 400 Bar, these units are the ideal choice for construction machinery, mining rigs, marine equipment, and industrial presses.

Key Technical Advantages:

• Advanced Bent-Axis Engineering: The unique rotating group geometry ensures superior mechanical efficiency and excellent self-priming capabilities, maintaining ultra-low noise even at high speeds.

• Bi-Directional Versatility: Functions seamlessly as a pump converting mechanical energy to hydraulic power, or as a motor delivering high-torque output, offering maximum system design flexibility.

• High-Pressure & Robust Bearings: Rated for 350 Bar (5000 PSI) continuous and 400 Bar (5800 PSI) peak pressure. The reinforced bearing system is built to handle significant radial and axial loads.

• Flexible Mounting & Shaft Options: Available in various shaft ends (keyed P, splined Z) and porting plate configurations (Rotation W, R) to meet ISO and standard installation requirements.

• Target Applications: Rotary drilling rig power heads, excavator travel drives, large machine tool hydraulic systems, marine winches, and road construction machinery.
