Single and double acting aluminium cylinders with lifting capacities of 20 to 150 tons and stroke lengths up to 250 millimeters use the latest developments in aluminium technology.Enerpac has introduced a new range of single and double acting aluminium cylinders with lifting capacities of 20 to 150 tons and stroke lengths up to 250 millimeters. This new line of high-force hydraulic aluminium cylinders is the most expansive one in the industry. Utilizing the latest in Alloy technology, high-strength coatings, seal design and bearing materials, the new cylinders have the strength of steel but all the advantages of aluminium.
The cylinders are lightweight, making them easy to transport and position.
The ergonomic benefits and power-to-weight ratio of Enerpac's new aluminium cylinders allow higher capacity cylinders to be used in a broad variety of applications, while decreasing the chance of muscle fatigue and increasing job efficiency.
Designed for a wide variety of construction and heavy load-moving applications, the line includes the single-acting RAC Series, the double-acting RAR Series, the RACL Series single acting lock-nut, and RACH Series single acting hollow plunger.
Each series is made from 7075T-6 aluminium alloy, with a complete Hard Kote treatment.
Composite bearings on all moving surfaces guarantee NO metal-to-metal contact, increasing side-load resistance and increasing cylinder life.
Removable hardened saddles and steel base plates, standard features of each series, protect the plungers and cylinder bases from surface contact.
Other standard features include stop rings to absorb eccentric loading and prevent plunger over-extension.
All single acting cylinders have a return spring for prompt plunger return.
