Product Highlights

This Enerpac RCH-121 single-acting hollow-plunger hydraulic cylinder with 12-ton capacity and 1.63" 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 has an FZ-1630 reducer and quick-connect AR-630 female coupler for use hydraulic hose with coupling (sold separately). Baked enamel body finish provides corrosion resistance. The collar is threaded to accept accessories (sold separately).
