Accelerate cycle times and increase production

Maximise acceleration with our patented floating ring cushion seal or alternative ball check design. Optimise deceleration with the fully adjustable cushioning system.


Heavy-duty, high-yield-strength steel throughout the cylinder – including the flange – ensures maximum durability. The threaded flange design enables reliable operation in even the most demanding applications. 

Hydraulic application and commercial engineering (ACE)

Safe, dependable performance

Captive screws prevent accidental removal, while still allowing easy adjustment. The SureSeal system – the connection between rod and wipers – ensures exceptional performance and durability. 

Minimise wear and extend seal life

Special wear bands eliminate metal-to-metal contact for longer cylinder life and increased load-carrying capability. The case-hardened, chrome-plated piston rod ensures maximum durability and seal life, resulting in less downtime.
