RC-TRIO Series Cylinders
The next evolution of the legendary Enerpac RC-Series hydraulic cylinder. The driving force of the Enerpac cylinder range, the RC-TRIO is as versatile as ever. Featuring a Trio Bearing System for enhanced durability and a hybrid spring-return system for faster retraction and even greater productivity.

New TRIO Bearing System

• Includes up to 4 high-performance wear bands that offer increased resistance to damage, reducing bearing load and increasing cylinder lifespan.
• Hardened composite material wear bands increase bearing surface area for greater sideload resistance - Significantly improving cylinder life.
• New high-performance Polyethylene seals last longer than ever, improving lifespan and keep you working for longer.

New TRIO Stop Ring

• Part of the Trio Bearing System, the Trio Stop Ring includes an additional wear band or high-strength bronze to absorb greater side load
• Capable of taking full cylinder extension force
• Features durable wiper to help prevent contamination from entering the cylinder during retract cycles.

New TRIO Spring System

• High-strength steel wire improves spring life
• Spring retention design improves serviceability while allowing higher pre-load during assembly
• Spring is easily removed without special tools.

Durable Piston Rod

• High-strength steel plunger for improved life and sideload resistance
• Nickel-plated plunger coating improves corrosion protection
• Internal plunger threads for easy tool fixturing.

Enhanced Ergonomics

• Standard carry handles on cylinders from 15 up to 25 kg. Sizes above 25 kg include certified lifting eyes or optional handles.
• Collar threads, plunger threads and base mounting holes enable easy fixturing.

Improved Saddle Retention

• Hardened plunger saddle protects plunger end during all lifting operations
• Easily removable for access to plunger mounting threads
• Tilt and smooth saddles available as accessories (compatible with new range of CATS-Series Tilt Saddles).

Enduring Compatibility

• For full compatibility and peace of mind, the new RC-Series model numbers, external dimensions and threads remain unchanged from prior RC-Series cylinders. Ensuring compatibility with historical versions and systems.
