About the Airtac SC100 Standard Cylinder SC100X250FA
The SC100X250FA is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, featuring a 100 mm bore and a 250 mm standard stroke. It generates a substantial push force of 3927 N at 0.5 MPa, rising to 7068 N at the maximum operating pressure of 0.9 MPa, making it a powerful actuator for medium-to-heavy industrial tasks.
This model is configured with a front rectangular flange (FA) for rigid end-face mounting, using accessory F-SC100FA. The 25 mm diameter piston rod is equipped with an M20x1.5 thread, and the total extended body length is approximately 438 mm. It operates with filtered air via PT1/2 ports and includes an adjustable air cushion to decelerate the piston smoothly.

Where the Airtac SC100 Standard Cylinder SC100X250FA Is Used
Conveyor Diverter Gates
The 3927 N push force at 0.5 MPa provides ample power to actuate heavy diverter gates or flippers on high-throughput conveyor systems, ensuring reliable material sorting.
Press-Fit Assembly Stations
Ideal for generating a controlled 7068 N insertion force at 0.9 MPa for pressing bearings, bushings, or pins into housings during automated assembly, with the front flange ensuring stable alignment.
Heavy-Duty Clamping Fixtures
Use this cylinder in welding or machining jigs where a robust, sustained clamping force is needed. The front flange mount allows direct bolting to a fixture plate for rigid, repeatable positioning.
Is the Airtac SC100 Standard Cylinder SC100X250FA the Right Cylinder?
Select the SC100 when your application requires a force class around 4000 N at standard shop air pressure. If your load is lighter, stepping down to an 80 mm bore reduces the push force to 2513 N at 0.5 MPa, saving energy and space. For higher demands, the 125 mm bore provides 6136 N at the same pressure.
For this 250 mm stroke, ensure the load is guided and side forces are minimal to protect the rod bearing. When replacing an existing cylinder, match five key points: the 100 mm bore, 250 mm stroke, PT1/2 port thread, the FA front flange mounting accessory, and the absence of a magnet (no -S suffix).
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 SC100X250FA 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. These values are based on the 100 mm bore and 25 mm rod diameter.
No. The AirTAC SC series is a tie-rod cylinder and is dimensionally shorter than an ISO 15552 profile cylinder. It is not a drop-in replacement. It will only directly interchange with another AirTAC SC tie-rod cylinder of the same bore, stroke, and mounting configuration.
