About the Airtac SC100 Standard Cylinder SC100X250H
The SC100X250H is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining a 100 mm bore with a 250 mm stroke. At 0.5 MPa it generates a push force of 3927 N, making it a capable actuator for medium-to-heavy industrial tasks. The piston rod measures 25 mm in diameter and connects via an M20x1.5 male thread.
This variant is equipped with Viton (FKM) seals, shifting the operating temperature range from the standard -20 to +70 °C up to 0 to +150 °C. This makes it suitable for high-temperature environments such as foundries, autoclaves, or engine test cells. The body length A is 188 mm, resulting in a total extended length of approximately 438 mm.

Where the Airtac SC100 Standard Cylinder SC100X250H Is Used
High-Temperature Clamping
With Viton seals rated for 0 to +150 °C, this cylinder is ideal for clamping fixtures in ovens, heated presses, or thermoforming machines where standard seals would fail.
Pallet Stop & Transfer
The 3927 N push force at 0.5 MPa provides ample power for stopping or transferring heavy pallets on conveyor lines, even in demanding logistics environments.
Heavy Part Ejection
Deploy the SC100X250H to eject large plastic or metal parts from hot molds, leveraging its high force output and thermal resilience for consistent, reliable cycles.
Is the Airtac SC100 Standard Cylinder SC100X250H the Right Cylinder?
Select the SC100 when your application needs roughly 4000 N of push force at standard plant pressure. If your load is lighter, stepping down to an 80 mm bore (2513 N at 0.5 MPa) can reduce air consumption and physical size. For a heavier load, the 125 mm bore provides 6136 N at the same pressure.
For this 250 mm stroke, ensure the load is guided and aligned with the rod axis. Any side force will create a bending moment on the 25 mm rod and the internal bearing, leading to premature seal wear or rod damage. For a direct replacement, match five points: 100 mm bore, 250 mm stroke, PT port thread, basic mounting (no brackets), and the Viton seal designation.
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 SC100X250H FAQ
At 0.5 MPa, the push force is 3927 N and the pull force is 3681 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 7068 N. The theoretical maximum force at 1.0 MPa is 801 kgf.
No. The SC100X250H is a standard double-acting cylinder and will not hold its position if air pressure is exhausted or lost. The piston can drift or drop under load. To hold a position without live pressure, you must add an external rod lock, a pilot-operated check valve, or a mechanical brake.
