Enerpac HCR-Series, High-Tonnage Cylinders

How to Choose an Enerpac HCR-Series High-Tonnage Cylinder

• Bore — the effective piston area sets the force output; match bore to the tonnage your job needs at working pressure rather than oversizing.
• Stroke (retracted / extended) — confirm both the collapsed height that fits your work envelope and the extended length needed to complete the move.
• Pin / mount size — verify the base, plunger, and any clevis or tilt-saddle mounting points line up with your fixture or press frame.
• Rod diameter — the rod (plunger) carries side load and column strength; match it to the original ram so guiding and stability hold under load.
• Port (SAE / NPT) — double-acting rams have two ports; confirm thread type and size so your couplers and hoses thread correctly on advance and retract.
• Action (single / double) — HCR-Series is double-acting, giving powered retract for faster cycling and horizontal or overhead work where gravity will not return the plunger.
• Working PSI — the HCR line runs at the Enerpac 10,000 PSI standard; pair it only with a pump, hose, and couplers rated to the same pressure.

Which High-Tonnage Cylinder Is Right for the Job?

HCR-Series double-acting rams suit horizontal, overhead, and high-cycle work where powered retract saves time. If your application holds a load for long periods, the Enerpac HCL-Series lock nut cylinders add a mechanical load-holding collar so hydraulic pressure is not the only thing carrying the weight. For general high-tonnage lifting, compare the Enerpac HCG-Series high-tonnage cylinders. When the job is lighter and gravity or load returns the plunger, single-acting rams such as the Enerpac RC-Series single-acting cylinders are simpler and lighter, while the lower-tonnage Enerpac RR-Series double-acting cylinders cover the same powered-retract need at smaller capacities.

Complete the System

A double-acting HCR ram needs a pump that can both advance and retract it, so pair it with an Enerpac ZE-Series electric pumps unit sized for the cylinder volume and equipped for two-port control. Connect both ports with high-pressure hose and Enerpac hydraulic couplers rated to 10,000 PSI so advance and retract lines seal cleanly and disconnect without trapping pressure.

Cross-Referencing an Obsolete High-Tonnage Cylinder

If your HCR-Series ram is discontinued or you are sourcing an equivalent to a competing high-tonnage cylinder, give us the bore, stroke, mounting, port type, and tonnage and we will match a current Enerpac equivalent from stock. Northern Hydraulics has cross-referenced hydraulic components since 1963, so send the data plate or old part number and request a cross-reference.
