Rexroth A2F Series Hydraulic Motor & Pump Parts (A2F28-A2F1000)

HYLINK supplies precision-engineered Rexroth A2F series fixed displacement bent-axis hydraulic pump/motor parts and complete rotary group repair kits for heavy-duty industrial and mobile machinery. Every component is manufactured to original specifications, 100% interchangeable with genuine Rexroth parts, and fully tested before shipment — providing a reliable, cost-effective replacement solution for repair shops, distributors, and fleet maintenance teams worldwide.

Key Specifications

Product Overview

The Rexroth A2F series is a classic high-pressure bent-axis axial piston unit, widely used as both a fixed hydraulic pump and motor in heavy-duty machinery applications. Operating under continuous high operating pressure and high rotary speed, key internal components—such as the cylinder block, tapered pistons, valve plate, and center pin assembly—are subjected to significant wear and high friction over time, leading to oil leakage, rotational speed drop, pressure loss, or excessive noise.

HYLINK manufactures high-precision complete rotary groups and individual replacement components across all Rexroth A2F displacements, from A2F28 to A2F1000. Engineered from high-strength forged alloy steel and wear-resistant bronze alloys, each part is CNC-machined to micron-level tolerance and verified with CMM inspection equipment. This enables repair technicians to replace specific worn parts directly without swapping out the entire assembly, significantly lowering overhaul costs and reducing machine downtime.

Available Components

Below is the standard component list for Rexroth A2F series hydraulic bent-axis units (A2F28 through A2F1000). Individual spare parts and complete overhaul repair kits are both available:

Quality Assurance & Manufacturing

Every HYLINK pump and replacement part undergoes strict quality control before shipment:

l Dimensional accuracy — checked with high-precision CMM (Coordinate Measuring Machines) to guarantee an exact fit with original pump housings.

l Material metallurgy — manufactured from premium forged steel and high-wear-resistant alloys to prevent premature fatigue.

l 100% performance test — every complete pump assembly is tested on our dynamic hydraulic test rig for pressure, flow rate and efficiency under full working load.

Packing, Shipping & Warranty

l Packaging — anti-rust protective film + heavy-duty foam cushioning + standard export fumigation-free wooden case (reinforced carton for small spare parts).

l Shipping — express courier (DHL / FedEx) for urgent repair orders; sea or air cargo for bulk orders.

l Warranty — 6 months quality assurance against manufacturing and material defects from the delivery date. In the event of a confirmed quality defect, HYLINK provides hassle-free replacement.
