Hollow Plunger Hydraulic Cylinder, 30 Tons Capacity Class, 7" Stroke
Enerpac RRH307 is a hollow plunger hydraulic cylinder that features 36 tons of max advance capacity and a stroke of 7". It has relief valves that prevent damage in case of over-pressurization and a baked enamel finish for increased corrosion resistance. Its collar threads enable easy fixturing. This hydraulic cylinder provides a double-acting operation for fast retraction.
The nickel-plated, floating center tube increases product life. A hollow plunger allows for both pull and push forces. Moreover, its plunger wiper reduces contamination, extending cylinder life. The RRH307 includes a CR-400 coupler and dust cap.
