Excavator Arm Cylinder Assy

Product introduction

The structure of hydraulic cylinder is various, and its classification methods are also varied: linear reciprocating motion type and rotary swing type according to the movement mode; single-acting type and double-acting type according to the action of hydraulic pressure; piston type, plunger type, multi-stage telescopic sleeve type, rack-and-pin type according to the structure form; and pull rod, earring, bottom foot, hinge according to the installation form. Axis, etc. Pressure level can be divided into 16 Mpa, 25 Mpa, 31.5 Mpa, etc.

We offer a large variety of shovel arm cylinder assy for crawler tracked machinery for world famous and domestic famous crawler-tracked crane like hitachi, kobelco, sumitomo, zoomlien, sany etc.

Quick detail:

Advantages

The thickness of Chromium plating is high to guarantee the long life of track adjuster piston. And we used imported high quality seal to guarantee the adjuster has good sealing property. What is more, the tube of track adjuster is made by forging. If the hydraulic pressure is too big. The tube will not be distorted.

Inspection

When assembling, we also need to test the sealing property by high pressure to see if there will be oil leakage or not.

Product design

Specialize in super big long non-standard cylinder

Designing Capacity: Bore size 20-800mm Stroke up to 16000mm

The max. rated work pressure is 32MPa.

Sealing system
All the hydraulic cylinders produced by our company adopt the seal ring products of Parker, Merkel and Busak+Shamban.

Piston rod
The piston rod is made of high strength carbon steel with precision grinding treatment. With the design concept of improving the rod strength and the high performance heat treatment, hard chrome plating and CNC tumbling, the even veins and high degree of finish of the surface is guaranteed, and it has good oil membrane at the surface, which improves the service life of the seal parts.

Guide sleeve

The sleeve is made of high strength spheroidal graphite cast iron and high strength steel under buffering inner bore copper welding treatment.

Cylinder block
The cylinder block is made of high strength carbon steel. The internal surface of the cylinder is designed with proper strength, size, and thickness of cylinder body, and it has good degree of finish and rigidity under the tumbling treatment which minimizes the inner friction, improves the wear resistance and prolongs the service life.

Piston and piston seals
The standard piston is of one-piece steel structure. The firm lock-up between the long screw thread and the steel ball is convenient for the installation and it also guarantees the reliable operation under high speed load. New design of screwing parts greatly improved the cross section where the piston rod bears the axial load and improves the strength of piston rod to the maximum.

Buffering
The buffering sleeve of the cylinder is made o

Application

Construction vehicle,excavator,crane,construction machinery,shipbuilding,metallurgy industry,hydro power project,agriculture machinery etc.
