Hollow Plunger Hydraulic Cylinders
Hollow plunger hydraulic cylinders (also known as center-hole cylinders) provide a versatile solution for tensioning, testing, pulling and lifting. A hydraulic cylinder with a hollow plunger allows for both pull and push forces. Choose between single-acting and double-acting models, and cylinder bodies constructed in either high-alloy steel or anodized aluminum. Enerpac Hollow Cylinders available for sale fully comply to ASME B30.1 (except BRD-RD-Series).
- RCH Series Hollow Hydraulic Cylinders are a single-acting, spring return. Most of these steel cylinders include base mounting holes, collar threads, and are finished with a tough baked enamel exterior coating.
- RRH Series Hollow Hydraulic Cylinders are double-acting for a faster and more controlled plunger return. They’re constructed from steel and finished with a baked enamel exterior coating. Collar threads and base holes are provided as standard for easy fixturing.
- RACH Series Hollow Hydraulic Cylinders are single-acting with a spring return. They feature a strong aluminum body and plunger, therefore offering a lighter solution than steel equivalents. Other features include a hard anodized exterior coating, bolt-on hollow removable saddles, and a steel base plate.
- RARH Series Hollow Hydraulic Cylinders are double-acting for a more controlled hydraulic return. Also constructed from strong aluminum, RARH-Series cylinders offer a lighter solution than steel equivalents. Other features include an anodized exterior coating, carry handles, and a steel base plate.
