The Enerpac RRH307 Hollow Plunger Hydraulic Cylinder is engineered for heavy-duty applications that demand both pushing and pulling force. With a 30-ton load capacity and double-acting design, it provides controlled force in both extension and retraction, ensuring faster cycle times and precise load handling. Its hollow plunger enables the use of threaded rods, cables, or bolts through the cylinder, making it ideal for cable tensioning, bearing extraction, anchor bolt pulling, and structural testing.
Constructed from high-strength alloy steel with a durable baked enamel finish, the RRH307 is built for long-term reliability even in rugged conditions. A chrome-plated plunger and integral wiper system safeguard against wear, corrosion, and contamination, while a removable hardened saddle protects the plunger surface during heavy use. Equipped with CR-400 couplers, this cylinder ensures quick and safe hydraulic connections.
Manufactured to meet ASME B30.1 safety standards and ISO 9001 certification, the RRH307 is a trusted solution for industrial, construction, and maintenance professionals.
