Adopt bimetallic composite process of steel base and copper‑alloy, with uniform hardness on friction surface and excellent anti‑friction performance. Under high‑speed rotating and high‑pressure friction condition of cylinder block, it resists frequent pressure shock, seizure and burning. Reduce surface scratch and groove caused by dry friction. Lower friction loss between valve plate and cylinder block. Maintain stable service life even under harsh condition with contaminated hydraulic oil and cut hydraulic pump failure risk.
Friction contact surface is ultra‑precision mirror‑ground with strict flatness and parallelness tolerance for tight even contact with cylinder block face. Oil window and relief grooves are machined fully per OEM drawing for smooth oil flow and reasonable high‑pressure pressure relief. Effectively control end‑face leakage, prevent pump flow loss and weak machine movement caused by warped surface. High‑precision locating holes ensure accurate installation and keep stable hydraulic pump output pressure.
