The role and basic requirements of the chrome steel rod

- Aug 31, 2019-

The piston rod is a connecting part that supports the work of the piston during the working process, and is mostly used in the use.

 

Among the cylinder and cylinder movement executing parts, it is a moving part with frequent movement and high technical requirements. Taking a hydraulic cylinder as an example, it consists of a cylinder, a piston rod (cylinder rod), a piston, and an end cover. The quality of its processing directly affects the life and reliability of the entire product. The piston rod has high processing requirements, and its surface roughness requirement is Ra 0.4-0.8 μm, which requires strict requirements on coaxiality and wear resistance.

 

The piston rod is effective in the production of its piston, piston ring, support ring, piston rod and the like. Depending on the type of construction, the piston can be divided into a cylindrical piston (longer than the diameter), a disc piston (longer than the diameter), a stepped piston, a combined piston and a plunger piston.
