The Enerpac RCH-603 Hollow Plunger Hydraulic Cylinder combines high capacity with versatility, making it ideal for applications where pulling force is as important as pushing force. With a 60-ton lifting capacity and 3-inch stroke, this single-acting spring-return cylinder is widely used for cable tensioning, bolt testing, bearing removal, and pulling operations in construction, maintenance, and heavy industrial environments.
The hollow plunger design allows threaded rods, cables, or bolts to pass through the cylinder body, enabling both tensioning and pushing in one tool. Built from high-strength alloy steel with a baked enamel finish, the RCH-603 provides exceptional durability even under tough working conditions. A hardened chrome-plated plunger resists wear and corrosion, while the integrated plunger wiper reduces contamination and extends seal life.
With its compact size and versatile mounting options, the Enerpac RCH-603 ensures maximum efficiency in demanding pulling and tensioning tasks where reliability is critical.
