About the Airtac SC80 Standard Cylinder SC80X20H
The SC80X20H is an 80 mm bore, 20 mm stroke double-acting tie-rod cylinder equipped with high-temperature Viton (FKM) seals, extending the operating range to 0–150 °C. This short-stroke model produces a push force of 2513 N at 0.5 MPa and 4523 N at the 0.9 MPa maximum operating pressure, driven by a 25 mm diameter piston rod.
With a compact body length A of 182 mm, the total extended length is approximately 202 mm. The adjustable air cushion (28 mm length) decelerates the piston at end-of-stroke, and the PT3/8 ports ensure straightforward pneumatic connections for hot-environment factory automation tasks.

Where the Airtac SC80 Standard Cylinder SC80X20H Is Used
High-Temperature Clamping
Short 20 mm stroke clamps parts in ovens or heated presses where ambient temperatures reach 150 °C, using the Viton-sealed SC80X20H for reliable 2513 N holding force.
Hot Melt Glue Actuation
Drives a dispensing head with a 20 mm advance in packaging lines. The FKM seals withstand aggressive hot-melt fumes, and the 25 mm rod resists bending under the short, direct push.
Foundry Pattern Ejection
Ejects small sand cores from a heated pattern plate. The 80 mm bore provides 4523 N of ejection force at 0.9 MPa, while the Viton seals endure the sustained radiant heat.
Is the Airtac SC80 Standard Cylinder SC80X20H the Right Cylinder?
Choose the SC80X20H when the application requires a large 80 mm bore force in a very short 20 mm stroke, combined with Viton seals for high-temperature duty up to 150 °C. If a lower force suffices, stepping down to a 63 mm bore (1559 N at 0.5 MPa) reduces air consumption and physical size. For higher force, the 100 mm bore delivers 3927 N at 0.5 MPa.
To guarantee a correct replacement, match five attributes: 80 mm bore, 20 mm stroke, PT port thread, the basic (no bracket) mounting configuration, and the absence of a magnet. This cylinder is a tie-rod design and is not dimensionally interchangeable with ISO 15552 profile cylinders.
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 SC80X20H FAQ
At 0.5 MPa (approx. 5 bar), the 80 mm bore generates 2513 N pushing force. At the maximum operating pressure of 0.9 MPa, it delivers 4523 N. The pull force on the retract stroke is 2268 N at 0.5 MPa due to the 25 mm rod reducing the piston area.
No. The AirTAC SC series is a tie-rod cylinder with a shorter overall body length than an ISO 15552 profile cylinder. It is not dimensionally interchangeable. It replaces another AirTAC SC 80 mm bore cylinder with the same stroke, port thread, and Viton seal option.
