Enerpac RACL-series aluminum lock nut cylinders are single-acting, high-pressure rams built to hold a load mechanically after lifting, so hydraulic pressure can be released while the load stays positioned. As a maker of 10,000 PSI hydraulic equipment with capacities from 5 to 1,000 tons, Enerpac engineers its lock nut cylinders for load-holding work in maintenance, construction, and heavy positioning jobs where a locking collar replaces continuous pump pressure. Northern Hydraulics carries this RACL-series range and can cross-reference discontinued Enerpac part numbers against current-production equivalents — request a cross-reference quote with your old model number.
Lock nut cylinders are specified by capacity (tons), stroke length, and collapsed/extended height, so confirm the load weight and the lift distance before selecting a model. To verify fit, match the cylinder tonnage to your heaviest expected load with margin, then check that collapsed height clears your work envelope. If you also need general lifting or pressing rams rather than load-holding units, compare the broader Enerpac hydraulic cylinders range; pair any cylinder with the right Enerpac hydraulic pumps for flow and pressure, and add hydraulic hoses rated to 10,000 PSI. For jacking-specific tasks, see Enerpac hydraulic jacks, or browse Enerpac hydraulic tools for accessories.
If an Enerpac lock nut cylinder in your fleet has been superseded or the part number no longer appears in current catalogs, Northern Hydraulics can match it to an equivalent current-production unit. We cross-reference legacy Enerpac model numbers against active series — for example, where older cordless and accessory lines were discontinued, Enerpac's current ranges provide the replacement path. Send the part number stamped on the cylinder, its capacity, and stroke, and we will identify the closest active equivalent. Request an Enerpac cross-reference quote for any obsolete RACL-series part.
