About the Airtac SC100 Standard Cylinder SC100X20H
The SC100X20H is a short-stroke, high-force double-acting cylinder from the AirTAC SC tie-rod series, configured with high-temperature Viton (FKM) seals. With a 100 mm bore, it delivers a substantial 3927 N of push force at 0.5 MPa, making it ideal for compact clamping, ejecting, or pressing operations in hot environments.
This model's 20 mm stroke, combined with the 188 mm body length, results in a very rigid assembly. The Viton seals shift the operating temperature range to 0 to +150 °C, ensuring reliable performance in autoclaves, foundries, or engine test cells where standard seals would degrade.

Where the Airtac SC100 Standard Cylinder SC100X20H Is Used
Hot Clamping Fixture
Short-stroke, high-force clamping of parts in a welding jig or heat-treating fixture, where ambient temperatures exceed 70 °C.
Foundry Knockout
Ejecting small castings from a hot mold, leveraging the 3927 N force at low pressure in a dusty, high-temperature foundry environment.
Autoclave Actuation
Operating a valve or mechanism inside a sterilization autoclave, where the 0-150 °C rating of the Viton seals is mandatory for process compliance.
Is the Airtac SC100 Standard Cylinder SC100X20H the Right Cylinder?
For applications needing even higher force in the same compact stroke, stepping up to the SC125 bore provides 6136 N at 0.5 MPa. If a longer stroke is required but the high-temperature capability is still critical, the SC100 series can be ordered with strokes up to 1500 mm. Ensure the 1/2 inch PT port is correctly matched to your existing fittings.
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 SC100 Standard Cylinder SC100X20H FAQ
At the maximum standard operating pressure of 0.7 MPa, the SC100 cylinder generates 5497 N of push force. The theoretical maximum at 1.0 MPa is 801 kgf.
No, the SC100X20H is a standard double-acting cylinder and will not hold its position if air pressure is exhausted or the directional valve is centered. For load holding, you must add an external rod brake, a mechanical lock, or a pilot-operated check valve.
