The first,pressure :the standard cylinder C, E, G three pressure level. C level in <6.3MPa E pressure range of the hydraulic cylinder (C cylinder). Hydraulic cylinderlevel in >6.3MPa~16MPa pressure range (E cylinder). G level in >16MPa~25MPa pressure range of the hydraulic cylinder (G cylinder).
The second, seal: C, E cylinder with simple structure, good wear resistance and wide range of application type rubber sealing ring. G uses high pressure, seal of V composite reliability.
The third, the dust: the hydraulic cylinders are used polyurethane or NBR no skeleton type dustproof ring.
The fourth, suitable medium: hydraulic oil, mechanical oil, emulsion. Do not apply phosphate.
Finally,Suitable temperature：minus forty degrees Celsius to one hundred and twenty degrees Celsius.
