Overview
HYLINK supplies precision-engineered Bosch Rexroth A15VSO series (A15VSO175, A15VSO210, A15VSO280) swashplate-design axial piston variable displacement pump replacement parts and complete rotary group overhaul kits. Specially engineered for heavy-duty industrial and open-circuit hydraulic applications, every component is manufactured to exact original dimensions and tolerances to ensure seamless fitment and dependable performance.
Product Overview
Bosch Rexroth A15VSO series variable axial piston pumps serve as high-capacity power units across demanding heavy industrial hydraulic applications. Under continuous high-load operations, internal rotating elements—including the drive shaft, cylinder block, pistons with slipper shoes, swashplate, ball guide, valve plate, and pressure hold-down plates—experience ongoing sliding friction and high mechanical stress. Surface wear on these critical contact interfaces causes internal fluid bypass leakage, thermal elevation, displacement output loss, and reduced system pressure response.
HYLINK manufactures high-precision replacement rotary groups and individual pump spare parts across the high-displacement A15VSO range (175, 210, and 280 cm³/rev). Produced from premium forged alloy steel and high-wear-resistant bronze formulations, each part undergoes micron-level CNC machining and 3D CMM quality verification. This enables service engineers and rebuilders to overhaul worn pump core assemblies cost-effectively and restore original volumetric efficiency without purchasing 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.
