Basic requirements for piston rod:

(1) Sufficient strength, stiffness and stability;

(2) Good wear resistance and high machining accuracy and surface roughness requirements;

(3) minimizing the influence of stress concentration on the structure;

(4) Ensure reliable connection and prevent loosening;

(5) The design of piston rod structure should be easy to disassemble and assemble the piston.

Piston rod is mainly used for hydraulic pneumatic, engineering machinery, automobile manufacturing piston rod, plastic machinery guide post, packaging machinery, printing machinery roller, textile machinery, conveying machinery for the axis, linear optical axis for linear motion.
