Processing and inspection:

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.

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.
