Rexroth A2F Series Fixed Displacement Axial Piston Pump / Motor
Guangdong Haozheng Hydraulic Equipment Co., Ltd. specializes in manufacturing high-efficiency Rexroth A2F series fixed displacement axial piston pumps and motors. Designed with a well-proven bent-axis structure for open or closed-circuit hydraulic drives, the A2F series can function seamlessly as either a hydrostatic pump or a reliable hydraulic motor. It is internationally recognized for its exceptional power density, high rotational speed tolerance, and uncompromised operating reliability under severe ambient conditions.
As an established global B2B hydraulic supply partner, Haozheng delivers complete A2F assemblies and high-precision replacement internal repair kits with 100% dimensional and functional interchangeability with original Bosch Rexroth components. To eliminate installation anomalies and guarantee peak volumetric output, every single unit undergoes comprehensive load trials and leakage calibration on our advanced hydraulic test benches before global dispatch.

Proven Fluid Power for Heavy Duty Mobile & Industrial Applications
Thanks to its robust bent-axis configuration and dual-function utility, our A2F series piston units excel under high vibration, high pressure, and heavy continuous duty cycles:
-
Metallurgical & Industrial Machinery (钢铁冶金与机床): Serving as a highly dependable constant-flow supply line or high-torque rotary motor in steel mills, heavy stamping presses, and shearing systems.
-
Marine & Offshore Deck Gear (船舶与港口机械): Driving constant-speed cargo winches, anchoring mechanisms, mooring systems, and offshore telescopic crane rotators.
-
Construction & Tunneling Equipment (工程机械与掘进机): Powering auxiliary rotary drives, high-pressure mixing loops, and track drive auxiliary motors in excavators, concrete pumps, and roadheaders.
-
Mining & Materials Handling (矿山与输送机械): Providing rugged, flame-resistant or standard fluid power drives for underground mining conveyor systems and rock crushing machinery.
The Haozheng Advantage: Precision Bent-Axis Machining & Global Packing Seals
Sourcing your hydraulic components from Guangdong Haozheng Hydraulic Equipment Co., Ltd. secures a high-tier B2B experience tailored for global distribution networks:
-
100% Drop-In Field Interchangeability: Our complete A2F units and internal replacement parts (including rotary groups, pistons, cylinder blocks, drive shafts, and premium seal kits) are machined to the exact micron metrics of original Rexroth units for smooth maintenance overhauls.
-
Rigorous Test Bench Performance Diagnostics: Every single A2F unit undergoes dynamic mechanical and volumetric efficiency verification under multi-hour pressure loads on our specialized test benches to ensure zero operational defects.
-
Heavy Marine Packaging Insulation: To safely protect heavy, high-pressure equipment against maritime moisture and handling shocks, all units are coated with anti-rust wrap and crated inside standard export fumigation-free wooden cases.
-
Strategic Global Stocking: We maintain an active inventory of popular medium displacements (such as A2F55, A2F80, and A2F107) to ensure rapid international delivery and effectively eliminate machinery downtime.
Frequently Asked Questions (FAQ)
Q1: Can an A2F unit be used as both a hydraulic pump and a hydraulic motor simultaneously? A: Yes, the A2F series features a highly symmetric bent-axis design. This allows identical units to function as either a fixed displacement pump converting mechanical rotation into fluid power, or as a hydraulic motor converting fluid flow into high-torque rotary movement. Always specify your configuration or shaft extensions when ordering.
Q2: What is the main structural benefit of a bent-axis A2F pump compared to a swashplate design? A: The bent-axis design features an angled piston cylinder arrangement relative to the drive shaft drive flange. This layout eliminates heavy structural thrust loads on the pistons and swashplates, resulting in exceptional self-priming capabilities, significantly higher permissible speeds, and supreme durability under severe pressure shocks.
Q3: What critical steps avoid failure during the initial startup of an A2F unit? A: Air binding or fluid starvation is the number one cause of instant mechanical failure on initial startup. To prevent dry running, you must completely pre-fill the A2F housing with clean, filtered hydraulic oil via the highest available case drain port, and verify that the suction line connections are fully airtight before starting the prime mover.
