Hydraulic Cylinder

Zhenhua is one of the professional hydraulic cylinder suppliers in Wuxi City, Jiangsu Province. We have more than 20 years of experience in the research, development and manufacturing of linear hydraulic motor. We can develop different kinds of cylinder with a diameter of 40-1000 mm and the maximum stroke of as long as 15 m. Our hydraulic devices, such as single action hydraulic cylinder, double action hydraulic cylinder, telescopic hydraulic cylinder, are widely used in excavator, forklift, crane, and so on.

Besides, we can develop special models on request. Different kinds of special solutions, especially the solutions for certain production sections, and technical supports are also available, so that we can make sure that the cylinders we designed and produced can completely meet client's needs.

A hydraulic cylinder is a drive component which can convert the power from pressurized hydraulic oil into the power for linear movements, so that the target mobile machines can achieve back-and-forth movements. Our products have simple structure, large power output, reliable and stable performance, convenient maintenance procedure, and wide applications.

Main Component Quality Control
Cylinder tube. Suitable material is adopted according to the cylinder's application. After proper pretreatment, skiving and roller burnishing, the tube can achieve great smoothness and toughness. The mechanical property and sealing elements' service lives are thus enhanced. Hydraulic oil port and flanges are usually needed to be added to the tubes by welding, which tends to lead deformation. However, we weld the parts right after the cold drawing of the pipes. Then the inner bore will be honed and roller burnished. Thus we can guarantee the great roundness and deformation resistance of the cylinder tube.

Piston rod. We will choose appropriate carbon steel or alloy steel according the cylinder's application. On the basis of high performance heat treatment, the rod's surface is subjected to hard chrome plating, nickel plating, and burnishing. Then the surface smoothness and anti-corrosion performance are improved and the rod's service life will be extended.

Sealing element. We have stable and reliable suppliers for the sealing elements, which are all imported components, so that the long service life and desirable working performance of the hydraulic cylinders are guaranteed. We can also choose certain brand of sealing element as client appointed.
