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 field of hydraulic power transmission. Due to its symmetrical bent-axis piston design, the A2F series can operate as either a Hydraulic Pump (converting mechanical energy to hydraulic) or a Hydraulic Motor (converting hydraulic energy to rotational torque). This category features the complete displacement spectrum from the compact A2F12 to the ultra-heavy-duty A2F500. Its robust construction makes it the industry standard for mobile machinery travel drives, crane winches, mining crushers, industrial power units, and marine equipment.

Key Technical Advantages:

• Dual Functionality: The fixed bent-axis architecture allows the unit to operate as a pump in open circuits or as a motor in any circuit type.

• Superior Self-Priming: As a pump, it offers excellent suction characteristics; as a motor, it delivers high starting torque and mechanical efficiency.

• High-Pressure Resilience: Rated for a continuous operating pressure of 350 Bar (5000 PSI) with peak capabilities reaching 400 Bar, ensuring stability under heavy shock loads.

• Versatile Configuration: Available with various shaft options (keyed or splined) and porting arrangements (W-type rear cover porting) to fit diverse installation spaces.

• Target Applications: Road rollers, concrete mixers, injection molding auxiliary drives, deck cranes, and scrap metal balers.
