Enerpac rch1003 Hollow Plunger Hydraulic Cylinder 103.1 Ton

Product Description

The ENERPAC rch1003 is a single-acting hollow plunger hydraulic cylinder rated for 103.1 tons of capacity with a 3.00-inch stroke. The hollow center design enables push, pull, and lifting operations from a single tool, making it well suited for structural tensioning, load testing, and precision maintenance tasks. The cylinder features a baked enamel exterior finish for corrosion resistance and a nickel-plated floating center tube that reduces side load damage and extends service life. Base holes and collar threads are machined into the body for straightforward fixturing in tight or complex setups.

The rch1003 is used in industrial maintenance, heavy equipment service, bridge and structural tensioning, and hydraulic testing applications. Its hollow plunger configuration gives technicians the flexibility to thread a rod or bolt through the cylinder bore, which is common in bolt tensioning, post-tensioning concrete work, and mechanical disassembly operations. The single-acting design relies on the load or a return spring to retract the plunger, which is standard practice in most tensioning setups.

Key Features

• 103.1-ton load capacity for heavy industrial and structural applications
• 3.00-inch stroke provides controlled, precise linear travel
• Hollow plunger bore enables push, pull, and bolt-through lifting configurations
• Baked enamel finish resists corrosion in demanding environments
• Nickel-plated floating center tube reduces side load stress and extends cylinder life
• Base holes and collar threads allow secure fixturing without additional fabrication

Compatibility

Designed as an OEM-style replacement or direct-use cylinder within the ENERPAC RCH-Series hollow plunger hydraulic cylinder family, compatible with hydraulic pumps and hose assemblies meeting the port and pressure specifications of the RCH Series.

Installation Notes

Installation and operation should be performed by qualified hydraulic technicians familiar with high-tonnage cylinder systems. Always depressurize the hydraulic system completely before connecting or disconnecting any hose or fitting. Ensure the cylinder is seated on a flat, stable surface rated for the full load capacity to prevent tipping or side loading. Never exceed the rated capacity or stroke length specified for this cylinder.
