Overview
HYLINK supplies precision-engineered Bosch Rexroth A11VO series (A11VO40, A11VO50, A11VO60, A11VO75, A11VO85, A11VO95, A11VO130, A11VO145, A11VO160, A11VO190, A11VO200, A11VO210, A11VO260) swashplate-design axial piston variable pump replacement parts and complete rotary group overhaul kits. Specially engineered for open-circuit mobile and industrial hydraulic systems, every component is manufactured to exact original dimensions and tolerances to ensure seamless fitment and dependable performance.
Product Overview
Bosch Rexroth A11VO series variable axial piston pumps serve as main hydraulic power units across demanding construction, mining, and industrial machinery. Under continuous high-duty operation, internal rotating parts—such as the drive shaft, cylinder block, pistons with slipper shoes, swashplate, ball guide, and valve plate—experience ongoing sliding friction and mechanical stress. Surface degradation across these critical contact interfaces causes internal fluid bypass leakage, oil temperature elevation, displacement output loss, and reduced system response.
HYLINK manufactures high-precision replacement rotary groups and individual pump spare parts across the complete A11VO displacement range from 40 to 260 cm³/rev. Produced from premium forged alloy steel and wear-resistant bronze formulations, each part undergoes micron-level CNC machining and 3D CMM quality verification. This allows hydraulic repair shops and equipment maintenance teams to cost-effectively rebuild pump core assemblies and restore original volumetric performance without purchasing full outer pump housings.

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.
