According to the cylinder pressure and inside diameter size, different steel tube would be selected.
ID ≤300mm, choose cold rolled precision seamless tube
300mm≤ID ≤500mm, choose hot rolled seamless tube
500mm≤ID ≤1000mm, choose forged tube
Steel grade : SAE1020, SAE1045, 27SiMn , S355JR, S355J2G3, St52-3, SUS304, SUS316L etc.
Inside boring and honing , roughness R0.2-R0.3
Inside chromed : if necessary ,tube inside chrome plating could be applied
steel grade : SAE1045, 42CrMo4, SUS410 ,SUS420, SUS304, SUS316L
Eternal company ensure that every piece piston rod would be surface hardened before plating, surface hardness is HRC55~60 , plating film thickness is 0.03~0.04mm if there is no other specific requirements.
Seal ring and O ring
According to the customers’ requirements and working condition, eternal company would choose suitable
seal ring kit, seal ring brand include: Parker, Merkel, NOK, Guangzhou Rubber institute, Taiwan brand etc. Eternal company would supply suitable seal solution for their customer so that hydraulic cylinder has more lifetime, easy maintenance and simple repairing.
Tube and flange welding
The welding on cylinder tube and flange would be Ultrasonic tested every time, the welding seam would be
cleaned before machining. Eternal company ensure that every welding seam has no any leak during lifetime.
