About the Airtac SC80 Standard Cylinder SC80X400SH
The SC80X400SH is a double-acting pneumatic cylinder delivering 2513 N of push force at 0.5 MPa and 4523 N at the maximum operating pressure of 0.9 MPa. With an 80 mm bore, 25 mm piston rod, and a 400 mm stroke, this unit is built for mid-to-heavy industrial tasks requiring high heat tolerance.
Equipped with a built-in magnet (-S suffix) and high-temperature Viton seals (-H suffix), this model operates reliably in environments from 0 to +150 °C. The adjustable air cushion (28 mm length) decelerates the piston smoothly at stroke end, protecting the end cap from impact. The body length A is 182 mm, giving a total extended length of approximately 582 mm.

Where the Airtac SC80 Standard Cylinder SC80X400SH Is Used
High-Temperature Process Automation
With Viton seals rated for 0-150°C, this cylinder is ideal for actuating dampers, valves, or clamps near furnaces, autoclaves, and heated presses.
Hot Material Forming & Molding
Provides the 4523 N of force at 0.9 MPa needed for ejector pins or core pulls in high-temperature injection molds and thermoforming equipment.
Heavy Part Sorting & Transfer
The 400 mm stroke and 2513 N push at 0.5 MPa reliably divert or lift heavy components on conveyor lines in foundries or heat-treatment facilities.
Is the Airtac SC80 Standard Cylinder SC80X400SH the Right Cylinder?
Select the SC80 when the SC63's 1559 N push at 0.5 MPa is insufficient for your load. If your application demands even higher force, step up to the SC100 bore, which provides 3927 N at the same pressure. Always match the bore, 400 mm stroke, PT1/4 port thread, and the -S magnet option when replacing an existing unit.
For this 400 mm stroke, be mindful of side loading. The 25 mm rod can experience bending under high radial forces. Use an external guide or linear rail to constrain the load and prevent premature rod bearing and seal wear. The -S magnet allows direct mounting of CMSG/DMSG/EMSG sensors for end-of-stroke detection.
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 SC80X400SH FAQ
At the standard 0.5 MPa operating pressure, the push force is 2513 N and the pull force is 2268 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 4523 N.
No. The SC80X400SH is a double-acting cylinder and will not hold its position if air pressure is exhausted or lost. The piston will drift or drop under load. You must use a mechanical lock, external rod brake, or pilot-operated check valve if load holding without live pressure is required.
