Overview
HYLINK supplies precision-engineered Bosch Rexroth A10FM series (A10FM28, A10FM45, A10FM63, A10FM71) swashplate-design axial piston fixed displacement motor replacement parts and complete rotary group overhaul kits. Specially designed for high-performance mobile and industrial hydrostatic drives, every part is manufactured to exact original tolerances and thoroughly inspected before shipment. This provides a high-performance, cost-effective replacement solution for repair shops, hydraulic distributors, and equipment maintenance teams worldwide.
Product Overview
The Bosch Rexroth A10FM series fixed displacement swashplate axial piston motors are widely utilized in open- and closed-circuit hydrostatic drives. Operating under continuous high rotation speeds and varying mechanical loads, internal rotating components—including the drive shaft, cylinder block, pistons with slipper shoes, swashplate/thrust plate, valve plate, and ball guide—experience continuous sliding friction and thermal stress over extended operation. Mechanical wear on these critical contact surfaces leads to reduced volumetric efficiency, elevated fluid heating, output torque drop, and internal leakage.
HYLINK manufactures high-precision complete replacement rotary groups and individual spare parts across the full A10FM range from 28 to 71 cm³/rev. Produced from premium forged alloy steel and high-wear-resistant bronze compositions, each component undergoes micron-level CNC machining and CMM quality inspection. This enables industrial maintenance engineers and hydraulic rebuilders to restore factory-level volumetric efficiency and motor performance without purchasing expensive complete casing assemblies.

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.
