The Enerpac RRH-series hollow plunger cylinder is a double-acting hydraulic cylinder built for pulling, tensioning, and push/pull work where the load must pass through the center of the ram. Enerpac, a high-pressure hydraulic manufacturer founded in 1910 and headquartered in Milwaukee, rates its industrial cylinder lines to 10,000 PSI, and the RRH hollow plunger family pairs the through-hole bore with double-acting hydraulic retraction for controlled cycling under load. Need to match a discontinued RRH part number to a current-production cylinder? Request an Enerpac cross-reference and we will identify the equivalent.
RRH cylinders are specified by tonnage capacity, stroke length, and bore (center hole) diameter, since the through-bore has to clear the rod, cable, or stud you are tensioning. To confirm fit, work from three figures: the rated capacity in tons, the maximum stroke your application requires, and the through-hole diameter that must pass the load. The RRH double-acting design is the choice when you need hydraulic retraction rather than gravity or load return; for single-acting pulling work, the RCH hollow plunger series is the related option. Compare the full Enerpac hydraulic cylinders range to scope solid-plunger RR and RC alternatives, and pair the cylinder with the right power source from Enerpac hydraulic pumps. For staging, lifting, and shop work see Enerpac hydraulic jacks, route pressure through Enerpac hydraulic hoses, and round out the setup with Enerpac hydraulic tools. The broader Enerpac catalog covers pumps, presses, and manifolds across the same 10,000 PSI system.
The RRH and RCH hollow plunger series are the modern alternatives Enerpac points to for tensioning and pulling applications, which makes them frequent cross-reference targets when an older hollow-ram cylinder is retired or hard to source. If you are holding a legacy Enerpac part number, a competitor's hollow plunger cylinder, or an RRH model that no longer fits your tonnage and stroke spec, we cross-reference it to a current-production RRH or equivalent. Send us the model number stamped on the cylinder along with your capacity, stroke, and bore requirements and we will match the replacement. Request an Enerpac RRH cross-reference quote.
