About the Airtac SC80 Standard Cylinder SC80X400H
The SC80X400H is an 80 mm bore, 400 mm stroke double-acting pneumatic cylinder built with high-temperature Viton (FKM) seals, extending its operating range to 0–150 °C. At 0.5 MPa it delivers 2513 N pushing force and 2268 N on the retract stroke, while at the maximum operating pressure of 0.9 MPa the thrust reaches 4523 N.
This tie-rod cylinder uses a 25 mm diameter piston rod with an M20x1.5 male thread and PT3/8 ports. The body length A is 182 mm, giving a total extended length of approximately 582 mm. Its 28 mm adjustable air cushion decelerates the piston smoothly at each end, protecting the end caps during high-cycle operation.

Where the Airtac SC80 Standard Cylinder SC80X400H Is Used
High-Temperature Automation
With Viton seals rated to 150 °C, the SC80X400H operates reliably in foundries, autoclaves, and drying ovens where standard seals would degrade, providing consistent clamping and actuation force.
Heavy Press & Clamping
Delivering 4523 N at 0.9 MPa, this cylinder suits medium-duty pressing, riveting, and part-clamping fixtures in metalworking and assembly cells that require a 400 mm working stroke.
Hot-Material Handling Gates
Use the SC80X400H to actuate diverter gates or stoppers on conveyors carrying hot materials, where the combination of long stroke, high force, and thermal resilience ensures continuous operation.
Is the Airtac SC80 Standard Cylinder SC80X400H the Right Cylinder?
Select the SC80 bore when the 50 mm bore's 982 N push at 0.5 MPa is insufficient; the step to 80 mm more than doubles the force. If your load is lighter and cycle speed is critical, the smaller SC63 (1559 N at 0.5 MPa) may offer a faster, more compact solution. For strokes of 400 mm, always check side-load conditions—an unsupported 25 mm rod at full extension can bend under transverse force, so consider an external linear guide or a guided cylinder if the load is not purely axial.
To replace an existing cylinder, match five points: 80 mm bore, 400 mm stroke, PT3/8 port thread, the basic (no bracket) mounting, and the absence of a magnet. The Viton seal variant (H suffix) is essential only when ambient or media temperatures exceed 70 °C or chemical resistance is required.
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 SC80X400H FAQ
At 0.5 MPa the pushing force is 2513 N and pulling force is 2268 N. At 0.7 MPa it reaches 3518 N push, and at the maximum operating pressure of 0.9 MPa the push force is 4523 N. For theoretical force at 1.0 MPa, expect 513 kgf.
No. The SC80X400H is a double-acting cylinder and will drift or drop if pressure is exhausted or the directional valve is centered. The adjustable air cushion only decelerates the piston near stroke end—it is not a lock. For load holding without live pressure, add a pilot-operated check valve or an external rod brake.
