About the Airtac SC80 Standard Cylinder SC80X120H
The AirTAC SC80X120H is a double-acting tie-rod cylinder with an 80 mm bore and 120 mm stroke, built with high-temperature Viton (FKM) seals for reliable operation in environments from 0 to +150 °C. At 0.5 MPa air pressure, it delivers 2513 N of push force, making it a strong mid-range actuator for industrial automation.
This model features a 25 mm piston rod, PT3/8 ports, and a 28 mm adjustable air cushion at each end to decelerate the piston smoothly. The body length A is 182 mm, giving a total extended length of approximately 302 mm. It is a genuine AirTAC SC series cylinder, designed as a compact tie-rod unit that is shorter than an ISO 15552 profile cylinder.

Where the Airtac SC80 Standard Cylinder SC80X120H Is Used
High-Temperature Process Automation
The Viton seals allow this cylinder to operate continuously in ovens, autoclaves, and foundry equipment where ambient temperatures reach up to 150 °C, providing 2513 N of reliable push force.
Heavy-Duty Clamping & Pressing
With 4523 N of force available at 0.9 MPa, the SC80X120H securely clamps large workpieces or composite layups during heated curing or forming cycles.
Hot-Material Gate & Diverter Control
Actuate gates or diverters on conveyors carrying hot asphalt, glass, or sterilized products, where standard seals would degrade quickly.
Is the Airtac SC80 Standard Cylinder SC80X120H the Right Cylinder?
Choose the SC80X120H when you need a robust 80 mm bore actuator that can withstand elevated ambient temperatures up to 150 °C. If your application requires less force, consider stepping down to the 63 mm bore (1559 N push at 0.5 MPa); for significantly higher force, the 100 mm bore offers 3927 N at the same pressure. Always verify that the 25 mm rod is adequately supported against side loads, especially with a 120 mm stroke.
For a direct replacement, match these five points: 80 mm bore, 120 mm stroke, PT3/8 port thread, the Viton (H) seal material, and the basic mounting style (no integrated bracket). This cylinder does not include a built-in magnet; if you need position sensing, select the -S variant or use external limit switches.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SC80 Standard Cylinder SC80X120H FAQ
At 0.7 MPa operating pressure, the theoretical push force is 3518 N and the pull force on the retract stroke is 2268 N. The maximum operating force at 0.9 MPa is 4523 N push.
Yes, the SC80X120H is dimensionally identical to the standard SC80X120. The only difference is the Viton (H) seal material, which shifts the operating temperature range from -20 to +70 °C up to 0 to +150 °C, making it suitable for hot environments where standard TPU seals would fail.
