Doosan excavator hydraulic cylinder

part number K1011026

DX255  boom hydraulic cylinder 

Our quality control:

We focus on every part's quality and material:

Rod seal:

Superior quality named-brand seals improve a longer life and seal effect.

Tube:

skived&burnished or vertical honing tube assures the concentricity and straightness.

Rod:

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.

This cylinder is available in both 2500 psi and 3000 psi, are clevis type hydraulic cylinders designed to meet the requirements of both the OEM and after-market users.

These standard stock cylinders are manufactured with high tensile cold drawn tube material precision honed for extended seal life.

The rod is ground and polished hard chrome plated, high tensile SAE C1045.

The piston, gland, cap and rod clevis are all manufactured from ductile iron 65-45-12 and the piston lock nut, clamp bolt, clevis clamp nut and tie rod nut are all Grade 10.

The tie rods are all ASTM 5140, high tensile with rolled threads for increased durability.

Each cylinder is 100% hydraulically tested.

Civil engineering construction is generally concerned with moving steel structures in barrages, shipping locks, or movable bridges. For the operation of these components, JDF has for decades been one of the leading suppliers of hydraulic cylinders with complete drive and control systems, as well as turnkey installations.

JDF places emphasis on the manufacture and commissioning of hydraulic cylinders with diameters up to 1000 mm, and lifts of up to 20 m, as well as the associated hydraulic aggregates and control equipment for the actuation of lock gates.
