Bosch Rexroth A10VSO Series Variable Displacement Axial Piston Pump Parts & Rotary Group (A10VSO10 to A10VSO140)

Key Specifications

Overview

HYLINK supplies precision-engineered Bosch Rexroth A10VSO series (A10VSO10, A10VSO18, A10VSO28, A10VSO45, A10VSO71, A10VSO100, A10VSO140) swashplate-design axial piston variable displacement pump replacement parts and complete rotary group overhaul kits. Specially designed for industrial machinery and mobile open-circuit hydraulic power units, every part is manufactured to exact original tolerances and thoroughly inspected before shipment. This provides a high-performance, cost-effective replacement solution for repair facilities, hydraulic distributors, and equipment maintenance teams worldwide.

Product Overview

The Bosch Rexroth A10VSO series variable displacement axial piston pumps serve as reliable power sources across a broad range of industrial and mobile hydraulic systems. Operating under continuous duty cycles and varying load conditions, internal rotating assemblies—including the drive shaft, cylinder block, pistons with slipper shoes, ball guide, valve plate, swashplate, and spring assembly—undergo continuous friction over extended operation. Surface wear on these critical contact interfaces leads to internal fluid bypass leakage, thermal elevation, displacement output loss, and reduced system response.

HYLINK manufactures high-precision complete replacement rotary groups and individual spare parts across the entire A10VSO frame size range from 10 to 140 cm³/rev. Produced from premium forged alloy steel and high-wear-resistant bronze compositions, each component undergoes micron-level CNC machining and 3D CMM quality inspection. This enables service engineers and rebuilders to restore original hydraulic pump volumetric efficiency and output without replacing expensive outer pump housing structures.

Available Components

Below is the standard component list for Bosch Rexroth A10VSO series hydraulic pumps. 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.

FAQ

Q: Are your SBS pump parts interchangeable with genuine Caterpillar parts?

A: Yes. All parts are produced to original specifications and dimensions and are 100% interchangeable — no modification is required during installation.

Q: What is the minimum order quantity?

A: 1 piece. We supply both individual components and complete rotary group / repair kits.

Q: How fast can you ship?

A: In-stock items are dispatched within 1–3 days; standard production orders take 5–8 days. Express and sea/air freight are both available.

Q: How do I confirm the correct part for my machine?

A: Send us your excavator model, pump model (SBS80 / SBS120 / SBS140) and the part name or photo — our technical team will confirm the correct item before you order.

Q: What warranty do you offer?

A: 6 months against manufacturing and material defects, with replacement support for confirmed quality issues.
