Enerpac RC158 Single Acting Hydraulic Cylinder

Product Description

The ENERPAC RC158 is a single-acting portable hydraulic cylinder designed for controlled linear force applications in industrial and construction environments. With a solid steel plunger and 25.13 cubic inches of oil capacity, this cylinder delivers reliable extension force and returns via spring or gravity on the retract stroke. The retracted length is 12.69 inches and the extended length is 20.69 inches, giving a working stroke suited for heavy lifting, pushing, and pressing tasks. The rod diameter of 1.63 inches provides structural rigidity under load. Licensed millwrights, maintenance mechanics, and hydraulic systems technicians are the typical installers.

The RC158 belongs to the ENERPAC RC series, a widely recognized line of general-purpose hydraulic cylinders used across industrial maintenance, structural steel work, bridge construction, heavy equipment repair, and shop press applications. Its compact retracted profile makes it practical in confined spaces where larger cylinders cannot be positioned. The cylinder is compatible with standard hydraulic hand pumps and power units that operate within the rated system pressure range for the RC series.

Key Features

• Single-acting design: extends under hydraulic pressure, retracts via external load or spring return
• Solid steel plunger construction for high load integrity and durability
• 25.13 cubic inch oil capacity supports full-stroke operation with compatible pump units
• 1.63 inch rod diameter resists side-load deflection in demanding push applications
• Plunger internal thread (1-8 UNC) and collar thread (2-3/4 - 16) allow saddle and extension accessory fitment
• Portable form factor with 12.69 inch retracted length for transport and tight-space deployment

Compatibility

Designed for use with hydraulic pump units and manifold systems compatible with the ENERPAC RC series cylinders. Verify system operating pressure matches the rated capacity of this cylinder before use.

Installation Notes

Installation and operation of hydraulic cylinders should be performed by qualified personnel familiar with hydraulic system safety. Fully depressurize and bleed the hydraulic circuit before connecting or disconnecting the cylinder. Ensure all fittings and hose connections are rated for the system operating pressure and are free of contamination before commissioning. Do not exceed the cylinder stroke limit or apply off-axis side loads that are not within the design parameters of this unit.
