Introduction and composition of the chrome plated steel rod

- Jun 28, 2019-

The chrome plated steel rod is a connecting part that supports the work of the piston. Most of them are used in the cylinder and cylinder movement executing parts, and are a moving part with frequent movement and high technical requirements. Taking a hydraulic cylinder as an example, it consists of a cylinder, a chrome plated steel 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 basic feature of the cylinder rod is the slender shaft machining, which is difficult to process and has always plagued the processing personnel.

       

The piston assembly includes: a piston, a piston ring, a support ring, a 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.
