Overview

HYLINK supplies precision-engineered Bosch Rexroth A10VNO series (A10VNO28, A10VNO45, A10VNO63, A10VNO85) swashplate-design axial piston variable displacement pump replacement parts and complete rotary group overhaul kits. Specially engineered for high-performance open-circuit industrial and mobile hydraulic systems, 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 A10VNO series variable displacement axial piston pumps are optimized for open-circuit hydraulic drives in mobile and industrial equipment. Operating under continuous duty cycles and varying hydraulic loads, internal rotating assemblies—including the drive shaft, cylinder block, pistons with slipper shoes, ball guide, valve plate, and cylinder spring assembly—experience ongoing mechanical friction over extended operation. Surface wear on these critical contact interfaces leads to internal bypass leakage, temperature elevation, displacement output loss, and reduced system pressure response.

HYLINK manufactures high-precision complete replacement rotary groups and individual spare parts across the entire A10VNO frame size range from 28 to 85 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.

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
