Pneumatic cylinder piston rod function

The C45 Pneumatic Cylinder piston rod is a connecting component that supports the operation of the piston. It is a frequently moving and technically demanding moving component, mainly used for the moving parts of oil cylinders and pneumatic cylinders. Taking a cylinder as an example, it consists of a cylinder tube, a piston rod (cylinder rod), a piston, and an end cap. The processing quality directly affects the lifespan and reliability of the entire product. The processing requirements for piston rods are high, with a surface roughness requirement of Ra0.4~0.8um, and strict requirements for coaxiality and wear resistance. The basic characteristic of cylinder rods is the machining of slender shafts, which is difficult and has always been a challenge for machining personnel. Piston rods are mainly used in hydraulic and pneumatic, engineering machinery, automobile manufacturing piston rods, plastic machinery guide columns, packaging machinery, printing machinery rollers, textile machinery, transmission machinery shafts, linear motion and linear optical axes.

 

Main regulations for pneumatic cylinder piston rod:

 

(1) To have sufficient compressive strength, flexural stiffness, and reliability.

(2) Good wear resistance, high machining accuracy and surface roughness.

(3) The structural type should avoid stress damage as much as possible.

(4) Ensure reliable connection and avoid looseness.

(5) The design of the piston rod structure should facilitate the disassembly of the piston.
