excavator spare part
We manufacture high quality hydraulic cylinder at lower cost.
We maintain quick response for various market.
Our quality control:
We focus on every part's quality and material:
Superior quality named-brand seals improve a longer life and seal effect.
skived&burnished or vertical honing tube assures the concentricity and straightness.
Induction hardened prior to chrome plating enhances the surface hardness. Enhanced chrome plating improve corrosion resistence and anti-scratch performance.
Piston:High pressure piston sealing material.
Making cylinder that are worthy of your equipment.
You will be without worry, when the cylinder willinterchange completely with the originalon your equipment.
The cylinder that are worthy of your equipment mean higher work efficency and less downtime won't let you down.

The machine include Skive Roller Burnishing Machines, Honing Machines, CNC Centers, Automatic welding machines, Grinders machine, Cylinder assembly& test benches, paining line.
Chrome-plated rod and bar products normally contain from 0.0005” maximum to 0.001” minimum hard chrome plate depending upon product specifications.
This hard chrome coating is applied primarily for wear resistance though it does provide considerable corrosion resistance as well.
Hard chrome plate deposits with a “micro-cracked” structure. Although hard chrome plate cannot corrode, the metal substrate it adheres to can if moisture and oxygen penetrate the chrome layer.
The result is a blistering and flaking of the chrome plate deposit from the metal substrate.
Once the rod is assembled into a cylinder and put into service, the fluid film on the surface of the rod provides additional corrosion resistance which is normally sufficient to protect it during its entire life.
