Introduction of threaded hollow optical shaft The threaded hollow optical shaft is a connecting part supporting the work of the piston. Most piston rods are used for cylinders and cylinder motion execution parts because it is a moving part that moves frequently and is technically demanding. Its raw materials include stainless steel and alloy steel, you can choose the right type according to your actual needs. It has sufficient strength, stiffness and stability, but also has good wear resistance and high machining accuracy. This hydraulic cylinder piston rod can meet different surface roughness requirements. Product characteristics and applications The effect of stress concentration on the structure can be minimized. It also ensures you are reliably connected and prevents loosening or other accidents. The structure is designed to facilitate the disassembly of the piston. It is mainly used in hydraulic and pneumatic, construction equipment, piston rod for automobile manufacturing, guide post for plastic machinery, roller for packaging equipment, printing equipment, textile equipment, conveying equipment with shaft, linear motion with linear optical shaft.
