Forged from high‑strength alloy steel with integral quenching‑tempering heat treatment. Piston bores are high‑precision honed for superior inner‑wall smoothness. Under high‑speed reciprocating sliding of pistons, it delivers outstanding wear‑resistance and effectively avoids bore scratching and galling. Withstands continuous impact of high‑pressure hydraulic oil, reduces internal leakage inside pump, keeps stable output pressure and extends overhaul cycle for heavy‑duty mine & earth‑moving applications.
The mating end‑face against valve plate is mirror‑ground with strict flatness & parallelism tolerance. Tight and even contact with valve plate minimizes end‑face leakage under high‑pressure condition, preventing flow loss and slow machine movement caused by warping‑wear. High‑precision internal spline bore meshes smoothly with drive shaft for stable power transmission, relieves spline shock‑wear and protects splines from tooth breaking damage.
