Enerpac RCH606 Hollow Plunger Hydraulic Cylinder

Product Description

The ENERPAC RCH606 is a single-acting, hollow plunger hydraulic cylinder designed for heavy-duty lifting, pushing, and positioning applications in industrial and construction environments. The hollow plunger design allows a rod, cable, or bolt to pass through the center of the cylinder, making it well-suited for tensioning, alignment, and through-hole pressing operations. With a 76.41 cubic inch oil capacity and a steel body, this cylinder delivers reliable, high-force output in a portable form factor. It is installed and serviced by hydraulic equipment technicians, millwrights, and industrial maintenance professionals.

The RCH606 is used in applications where a through-hole configuration is required, such as bolt tensioning, pipe pulling, structural alignment, and heavy component pressing. Its compact retracted length of 12.75 inches and extended length of 18.75 inches make it practical for confined or access-restricted work areas. The RCH series is a standard industrial cylinder line, and this unit is appropriate for both shop and field use where a portable hydraulic power source is available.

Key Features

• Hollow plunger design allows rod, cable, or fastener to pass through the center for tensioning and alignment tasks
• Single-acting actuation extends under hydraulic pressure and retracts mechanically or by gravity
• 76.41 cubic inch oil capacity supports full-stroke force delivery
• Steel body construction for durability in industrial environments
• Plunger internal thread size of 2-3/4-16 for accessory attachment
• Collar thread of 6-1/4-12 for mounting or toe ring fitment
• Center hole diameter of 2.12 inches accommodates a range of through-bolt and rod sizes

Compatibility

The RCH606 belongs to the ENERPAC RCH series of hollow plunger cylinders. It is compatible with single-acting hydraulic hand pumps, air-hydraulic pumps, and electric pump units that match the cylinder port connection. Consult pump flow and pressure ratings to confirm compatibility before use.

Installation Notes

Installation and operation of hydraulic cylinders should be performed by qualified hydraulic technicians or millwrights familiar with high-pressure hydraulic systems. Depressurize and isolate the hydraulic circuit completely before connecting or disconnecting the cylinder. Ensure all fittings and couplers are rated for the system operating pressure and are fully engaged before applying hydraulic force. Never place hands or body parts in the load path or in the cylinder stroke zone during operation.
