The Enerpac RCH306 Single-Acting Hollow Plunger Hydraulic Cylinder delivers both power and versatility for heavy-duty applications where a traditional solid plunger cylinder cannot be used. With a 36.1-ton lifting capacity and an extended 6.13-inch stroke, it is engineered for applications such as cable pulling, bolt tensioning, bearing removal, and general maintenance lifting.
Its hollow plunger design allows tensioning rods, cables, or bolts to pass through, enabling both push and pull operations. Constructed from high-strength alloy steel with a baked enamel finish, the cylinder ensures long-lasting durability. The hardened chrome-plated plunger reduces wear, while the integral wiper protects against dirt and debris, extending service life.
As a single-acting, spring-return model, the RCH306 simplifies retraction after use, providing safe and efficient operation. Meeting ASME B30.1 safety standards and produced in ISO-certified facilities, it is a trusted choice for demanding industrial environments.
