Product feature
Sealing system
All the hydraulic cylinders produced by our company can meet the requirements of construction machinery, mining machinery, hoisting and transportation machinery. The seal system is of unique design, which effectively solves the problems of oil leakage at the piston rod and the dry friction of piston.
 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. All the piston rods and piston parts has the safety factor of at least 4:1 at the minimum cross section, and the factor is based on the rated load.
 Guide sleeve
The sleeve is made of high strength spherical graphite cast iron and high strength steel under buffering inner bore copper welding treatment. It can avoid the cementation and pull of steel parts caused by the friction of buffering sleeve and guide sleeve. The support ring of Phenol-formaldehyde material inside the guide sleeve features high bearing capacity, and it can eliminate the contact between the piston rod and guide sleeve. The reasonable collocation improves the side bearing capacity, impact absorption, and the contact area, meanwhile it minimizes the bearing contact stress and prolongs the service life of hydraulic cylinder and seal parts.
 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.
The seal structure of piston ensures the normal operation of hydraulic cylinder. And there is dust collecting ring mounted at the front and the back of main seal and support ring, which prevents the piston seals from dust and prolongs the service life.
