Firestone's Airstroke™ Polyactuators

Firestone's Airstroke™ Polyactuators serve as a space-saving alternative to traditional hydraulic and pneumatic cylinders.  Ideal applications include conveyor transfer sections and roller brakes or applications requiring .6 inch (15mm) clearance.  Polyactuators have "daisy chain' along tubing capabilities and are lab tested for five million cycles. 

The line-up is comprised of three models: 50-P (50mm/1.97in), 70-P (70mm/2.75in) and industry leading 120-P (120mm/4.72in) units lifting loads up to 100 pounds (45kg) with a .5 inch (12.7mm) stroke at 50psi.

Polyactuator Applications

Heat Sealing

  • • Compact height allows for minimum starting height and space requirements.
  • • The polyactuator's large effective area allows a significant force to be applied. 

Roller Friction Brake

  • • Compact, allowing conveyor mounting close to floor.
  • • The polyactuator's large effective area allows a significant force to be applied. 

Right Angle Transfer Section

  • • Compact starting height provides stroke capabilities up to two times the compressed height. 
  • • Reduced cost in initial purchase price, installation and maintenance.
