Enerpac rch-306 Hollow Plunger Hydraulic Cylinder

Product Description

The ENERPAC rch-306 is a single-acting, hollow plunger hydraulic cylinder designed for testing, maintenance, and tensioning applications in industrial and trade environments. The hollow center plunger allows the cylinder to be used in push, pull, and lifting configurations, giving technicians and engineers flexible deployment options across a range of setups. Built for demanding service conditions, the rch-306 features a baked enamel finish for corrosion resistance and a nickel-plated floating center tube that reduces side load damage and extends service life. This cylinder is part of the RCH series, rated for capacities above 20 tons.

The rch-306 is suited for heavy industrial applications including structural tensioning, bolt tensioning, mechanical testing rigs, and maintenance press work. The center hole design incorporates base holes and collar threads to simplify fixturing and secure positioning during operation. This cylinder is typically installed and operated by hydraulic technicians, mechanical engineers, and maintenance professionals working in industrial, construction, and manufacturing environments.

Key Features

• Hollow plunger design enables push, pull, and lifting configurations
• Single-acting hydraulic operation for straightforward force application
• Baked enamel finish resists corrosion in tough service environments
• Nickel-plated floating center tube reduces side load damage on cylinders rated over 20 tons
• Base holes and collar threads allow easy and secure fixturing
• Built for high-demand testing, tensioning, and maintenance applications

Compatibility

Designed as an OEM-style component within the ENERPAC RCH series of hollow plunger hydraulic cylinders for industrial tensioning and maintenance applications.

Installation Notes

Installation and operation should be performed by qualified hydraulic technicians familiar with high-pressure hydraulic systems. Relieve all hydraulic pressure and isolate the system before making connections or performing service. Ensure the cylinder is properly aligned with the load path to avoid side loading, which can damage the plunger and seals. Follow applicable industry safety standards and the manufacturer service documentation for connection torque and pressure ratings.
