Enerpac Hydraulic Cylinders

Enerpac Hydraulic Cylinders


High-quality hydraulic tools are vital in ensuring safe, accessible, and productive work environments. At Metro Hydraulic, we offer an extensive line of Enerpac hydraulic cylinders. Enerpac is the world’s leading manufacturer of hydraulic pressure tools and other controlled force products. Enerpac hydraulic cylinders are trusted worldwide and offer maximum force, making them the optimal solution for the precise movement and positioning of heavy objects.



Types of Cylinders

At Metro Hydraulic, we offer the following Enerpac hydraulic cylinders:

Single-Acting Cylinders

Single-Acting Cylinders

Enerpac’s single-acting RC Series cylinders are specifically designed to function well in a range of positions. These cylinders are equipped with heavy-duty pretension springs for increased retraction speed, and most models feature plunger threads, collar threads, and base mounting holes for easy and secure fixturing in various positions. Enerpac single-acting cylinders are made from high-strength alloy steel for enhanced durability, and nickel plating is an option for most models. All models feature a baked enamel finish for improved corrosion resistance, CR-400 couplers and dust caps, and heavy-duty return springs.
Double-Acting Cylinders

Double-Acting Cylinders

Enerpac double-acting cylinders feature plunger threads, collar threads, and base mounting holes on most models for easy fixturing. The RR Series offers removable hardened saddles for protection during lifting and pressing motions. The cylinders have increased longevity due to their built-in safety valves, which protect against over-pressurization. They also feature CR-400 couplers and plunger wipers for the reduction of contamination as well as a baked enamel finish for improved corrosion resistance. Although single- and double-acting cylinders have some similarities, double-acting cylinders differ in that both sides of the piston are alternatively acted on by fluid, creating force in both directions.
Hollow Cylinders

Hollow Cylinders

Enerpac’s hollow plunger cylinders are highly versatile and lightweight. They have collar threads for easy fixturing and a baked enamel finish for increased resistance to corrosion. This long-lasting cylinder option is available in both the RRH and RCH Series and is ideal for testing and tensioning. Thanks to its hollow design, it can provide both push and pull forces. RCH single-acting hollow plungers feature smooth nickel-plated hollow saddles, while RRH double-acting models offer relief valves to eliminate damage from over-pressurization. Models with capacities of over 20 tons feature a nickel-plated floating center tube and single-acting spring return, both of which serve to increase the cylinder’s longevity.
Lock Nut Cylinders

Lock Nut Cylinders

Enerpac lock nut cylinders offer safe and positive mechanical load holding. Their hardened surface makes them able to resist cyclic wear and side-loading. These cylinders are specifically designed to withstand 10% side-load and up to 90% of maximum stroke. They feature low-friction locking rings and can lock without hydraulic pressure for when extended load holding is necessary. Their mechanical load locking function makes Enerpac lock nut cylinders a safe option for extended holds in situations where hydraulic pressure can be interrupted. These cylinders are weather-protected and contain an overflow port, which serves to prevent plunger blow-out by limiting strokes. Enerpac lock nut cylinders have certified lifting eyes and base mounting holes, and the plunger is further supported by replaceable bearings. The HCL Series features a synthetic coating for added corrosion resistance and smoother operation during use.
High Tonnage Cylinders

High Tonnage Cylinders

Enerpac’s high tonnage cylinders are the optimal choice for applications requiring heavy lifting. They have a hardened surface to resist side-loading and cyclic wear, and they can withstand 10% side-load of maximum capacity. These cylinders utilize a maximum of 10,000 psi internal pressure and have lifting capacities ranging from 50 to 1,000 tons. They are designed for the plunger to receives added levels of support throughout the stroke thanks to upper and lower replaceable bearings. Enerpac high tonnage cylinders are weather-protected and feature collar threads, base mounting holes, and certified lifting eyes. The HCG and HCR Series offer additional safety and protection from piston blow-out through the inclusion of mechanical stop ring.
In addition to those above, RSM/RCS Series low height cylinders are also available from Enerpac. For more information on specific models of lock nut, high tonnage, hollow, and single & double acting cylinders, find our Enerpac cylinders catalog.
