1. Cylinder tube size and choice
A. According to the cylinder pressure and inside diameter size, different steel tube Would be chosen.
a. ID ≤300mm, cold rolled precision seamless tube would be choose
b. 300mm≤ID ≤500mm, hot rolled seamless tube would be choose
c. 500mm≤ID ≤1000mm, forged tube would be chosen
B. Cylinder tube steel grade: 27SiMn
a. Cylinder tube inside boring and honing, roughness R0.2-R0.3,
b. Cylinder tube inside chromating: if necessary, tube inside cremating could be applied
2. Piston rod is a very important part for hydraulic cylinder.
A. Piston rod steel grade: SAE1045, 42CrMo4, SUS410, SUS420, SUS304, SUS316L
B. Piston rod cremating and surface hardness.
DALLAST ensure that every piece piston rod would be surface hardened before cremating,
surface hardness is HRC55~60, Chromating film thickness is 0.03~0.04mm if there is no other specific
3. Seal ring and O ring
According to the customers’ requirements and working condition, DALLAST would choose suitable seal ring kit, seal ring brand include: Parker, Merkel , NOK . DALLAST would supply suitable seal solution for their customer so that hydraulic cylinder has more
lifetime, easy maintenance and simple repairing.
