Product introduction

Hydraulic cylinder is a hydraulic actuator which converts hydraulic energy into mechanical energy and makes linear reciprocating motion (or swing motion). It has simple structure and reliable operation. When it is used to realize reciprocating motion, it can avoid the deceleration device, and has no transmission clearance and smooth movement. Therefore, it has been widely used in various mechanical hydraulic systems. The output force of the hydraulic cylinder is proportional to the effective area of the piston and the pressure difference on both sides. The hydraulic cylinder is basically composed of cylinder barrel and cylinder head, piston and piston rod, sealing device, buffer device and exhaust device. Buffer and exhaust devices depend on specific application occasions, while other devices are indispensable.

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

Advantages

Our key products include 9 series of hydraulic cylinders made for: excavators, loaders, forklifts, dump trucks, mining equipment, agricultural equipment, port machines, sanitation machines and other special machines. There are more than 1200 models.

The ‘roughness’ of the inside of the tube has been reduced to 0.01 from 0.04 µm which, along with a smoother, harder surface, was achieved by processing with the most advanced SRB machinery.

The surface of the rod is treated using advanced Japanese technology to minimize the pores and to improve the adhesion and the hardness of the chromium coating layer and to increase the brightness and the anti-corrosion properties.

A six-headed polishing machine buffs the rod twice to greatly reduce the frictional coefficient and surface roughness and to effectively prolong the service life of the cylinder.

In the mean time, we have the advanced CNC machine tools, a HM6300 horizontal machining center, a Panasonic welding robot, parts cleaning agent, automatic assembly lines, automatic painting equipment etc. to ensure a 360-degree quality control of the production process. We check all of the products, using fully equipped facilities and advanced instruments, regarding the performance, structure, size tolerance, roughness, hardness, pressure and sealing to ensure the product quality meets the requirements of our different customers.
