Excavator is the most widely used construction machinery for Excavator Arm/boom/bucket hydraulic Cylinder.

We can make full size excavator cylinders from mini excavators to extremely large excavators

including Excavator Arm/boom/bucket hydraulic Cylinder / steering cylinders.

Arm Cylinder/Boom Cylinder/Bucket Cylinder:The cylinder liners are made of cold drawn seamless steel tubes with strong

honing technique. The cylinder length can reach up to 7m with diameters from φ40 to φ500. The piston rods are made of

chrome steel with special heat treatment. The surface which makes it high in smooth finish with tough inside and hard outside.

The quality of our cylinders is guaranteed by the test of high-pressure test bed.

Arm Cylinder/Boom Cylinder/Bucket Cylinder Main Features:

1.Rod seal:superior quality named-brand seals improve a longer life and seal effect polyurethane U-packing rod seals

/buffer sealsbonded-to-metal wiper seals custom seals available

2.Tube:Skived&burnished or vertical honing tube assures the concentricity and straightness

3.Bushing:Hardened steel bushing or copper bushing

4.Eye:All eyes are made of forged high strenght steel improve cylinder not only in appearance but in mechanical performance

5.Rod:Induction hardened prior to chrome plating enhances the surface hardness,enhanced chrome plating improve

corrosion resistence and anti-scratch performance

6.Piston:High pressure piston sealing material:teflon or nylon seals.High precision machining maximize the consistency of parts.

7.Cap:All caps are made of forged high strength steel
