The Guanshuo’s China Pneumatic drive motor shaft is coated with a special anti-corrosion layer or made of stainless steel base material, which is resistant to oil/water-containing cavitation in compressed air and mild corrosion by hydraulic oil/lubricating oil in pneumatic systems. It meets the anti-corrosion requirements for the purchase of pneumatic equipment under dry and wet mixed working conditions.
42CrMo, 20CrMnTi or 304/316 stainless steel is preferred.
After quenching and tempering and carburizing and quenching treatment, the core has strong toughness and can withstand the instantaneous impact load of pneumatic drive, meeting the anti-impact requirements of high-frequency start-stop procurement of pneumatic equipment. The tolerance of the shaft body seal fit section reaches IT5 - IT6, with a surface roughness of Ra0.1-0.4μm. The shape and position tolerances (roundness ≤0.005mm, cylindricity ≤0.008mm) are seamlessly fitted with pneumatic sealing rings/oil seals, meeting the assembly standards for high-sealing requirements procurement.
