Product Overview
The Yuken A series (including A10, A16, A22, A37, A56, A70, A90, A100, A145, and A220) is an industry-standard variable displacement axial piston pump platform renowned for its low noise levels, high efficiency, and energy-saving performance in industrial hydraulic systems. Under long-term continuous operation, internal rotary group components—such as the cylinder block, piston shoes, valve plate, and swashplate—gradually experience surface wear, which can result in reduced system pressure, increased oil leakage, slower cycle speeds, or elevated operating noise.
HYLINK manufactures high-precision complete rotary groups and individual replacement components across all Yuken A series pump displacements. Crafted from high-strength forged alloy steel and wear-resistant bronze alloys, each part is precision CNC-machined and verified via CMM inspection. This allows maintenance technicians to replace specific worn parts directly without purchasing a whole new pump assembly, significantly reducing overhaul costs and minimizing machine downtime.

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.
