This Enerpac RCH-302 single-acting hollow-plunger hydraulic cylinder with 30-ton capacity and 2.50" stroke has a one port, spring return of the single piston rod, and a hollow plunger for use in applications where the need for push and pull forces might alternate, such as testing, maintenance, and tensioning applications. The single-acting hydraulic cylinder uses liquid pumped through its single port for rod extension and an internal spring for rod retraction to produce continued movement. The port is a quick-connect CR-400 female coupler for use with a CH-604 male coupler (sold separately). Baked enamel body finish provides corrosion resistance. The center tube floats to extend the life of the seals. The threaded collar accepts accessories (sold separately).

Enerpac manufactures high-pressure tools and equipment for industrial applications. The company, founded in 1910, is headquartered in Menomonee Falls, WI.
