Enerpac RCH121H Compact Hydraulic Cylinder Base Mount

Product Description

The ENERPAC RCH121H is a compact, single-acting hydraulic cylinder designed for high-force push applications in tight-clearance environments. Single-acting operation means hydraulic pressure extends the ram while a built-in spring or external load retracts it, making this cylinder well-suited for pressing, lifting, and clamping tasks where a double-acting circuit is not available or practical. The base mounting hole provides a secure, fixed attachment point that keeps the unit stable under load. At 6.2 pounds, the RCH121H is portable enough for field work while still offering the structural integrity expected of ENERPAC hydraulic tooling. Licensed hydraulic technicians, maintenance mechanics, and heavy industrial tradespeople are the typical installers.

This cylinder is used in industrial maintenance, fabrication, and tooling applications where controlled linear force is needed in a confined space. The base mounting hole mount allows the cylinder to be bolted directly to a work surface, fixture, or frame, making it appropriate for both portable field setups and semi-permanent press or clamping stations. It is commonly found in manufacturing facilities, steel erection, bridge maintenance, and general mechanical service environments.

Key Features

• Single-acting actuation: hydraulic pressure extends the ram, spring or load retracts
• Base mounting hole for secure, fixed-position installation
• Compact form factor designed for restricted-access work areas
• Lightweight at 6.2 pounds for portability in field service
• OEM-quality construction consistent with ENERPAC hydraulic tooling standards

Compatibility

Designed as an OEM-style replacement or supplemental cylinder for single-acting hydraulic systems requiring a compact cylinder with a base mounting hole configuration.

Installation Notes

Installation should be performed by a qualified hydraulic technician or industrial mechanic familiar with high-pressure hydraulic systems. Depressurize and isolate the hydraulic circuit fully before connecting or disconnecting any fittings. Ensure all hydraulic connections are rated for the system operating pressure and that fittings are torqued per the hydraulic component manufacturer's general guidelines. Inspect the mounting surface and hardware for proper load-bearing capacity before placing the cylinder into service.
