Featuring a Trio Bearing System for enhanced durability and a hybrid spring-return system for faster retraction and even greater productivity.

Build

• 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 keeping 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
