HC heavy hydraulic cylinder can carry real loads. this series of heavy hydraulic cylinder are mainly used in metallurgy equipment and heavy machinery, and also suitable for other industries. HC heavy hydraulic cylinder tube is made of carbon steel, after is honed the inside diameter tolerance level in the H7 ~ H9 with surface roughness of 0.3 ~ 0.6μm ,oil seal and other seal products are imported with high precision, resistant to oil, rusty, friction, loss, and pressure.various parts are precision machining by milling and CNC lathe, good fit, high service life, easy to maintenance. Here are some parameters of HC heavy hydraulic cylinder: Bore sizes of cylinder:φ40，Ͽ0，Ͽ3，Ͽ0，Ͽ00，Ͽ25，Ͽ40，Ͽ50，Ͽ60 Power fluid: Filtered oil Material of dhliner bareel: Carbon steel STKM-13C The range of pressure(MPa): 0.3 ~ 21MPa(3 ~ 210kg∕cm2) The range of temperature: -10 ~ +110(ℿ The range of speed （mm∕sec＿8 ~ 300（mm∕sec＿
