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.
The cylinder block is made of high strength carbon steel. The
internal surface of the cylinder is designed with proper strength,
