Enerpac rr-5020 Double-acting Hydraulic Cylinder 55.3 Ton

Product Description

The ENERPAC rr-5020 is a double-acting, general-purpose hydraulic cylinder with a solid plunger rod, built for heavy industrial pushing, pulling, and pressing applications. It delivers 55.3 tons of advance force and 11.8 tons of retract force at a rated working pressure of 10,000 psi. The steel housing is finished in baked enamel for corrosion resistance. With a 3-3/4 inch bore and a 20.13 inch stroke, this cylinder is suited for high-force positioning and maintenance tasks where both extension and retraction must be powered. Licensed hydraulic technicians and millwrights are the typical installers.

The rr-5020 belongs to the ENERPAC RR series of double-acting cylinders, which are designed for general-purpose industrial use. Base mounting makes it straightforward to fixture into existing tooling, press frames, or maintenance jigs. The 3/8-18 NPTF port accommodates standard hydraulic hose fittings. The 2.81 inch rod diameter and 5 inch OD housing are sized for the structural loads this cylinder generates. Typical applications include steel fabrication, heavy equipment maintenance, bridge and structural work, and industrial production tooling.

Key Features

• Double-acting design provides 55.3 ton advance and 11.8 ton retract force under power
• 10,000 psi rated working pressure consistent with standard hydraulic pump systems
• 20.13 inch stroke with 28.88 inch retracted height for extended reach applications
• 3/8-18 NPTF port for leak-resistant connection to standard hydraulic lines
• Steel housing with baked enamel finish for durability in industrial environments
• Base mounting configuration for fixed-position tooling and press setups

Compatibility

Designed as an OEM-style replacement or direct-application cylinder within the ENERPAC RR series, compatible with 10,000 psi hydraulic systems using 3/8-18 NPTF ported connections.

Installation Notes

Installation should be performed by a qualified hydraulic technician or millwright familiar with high-pressure hydraulic systems. Depressurize and bleed the hydraulic circuit fully before connecting or disconnecting any fittings. Ensure all port connections are rated for 10,000 psi service and that the mounting surface can sustain the full advance load of 55.3 tons. Follow applicable ASME and OSHA guidelines for hydraulic tooling setup and load control.
