About the Airtac SC100 Standard Cylinder SC100X250FB
The AirTAC SC100X250FB is a 100 mm bore double-acting pneumatic cylinder delivering 3927 N of push force at 0.5 MPa (up to 7068 N at 0.9 MPa). With a 250 mm stroke, this model uses a 25 mm diameter piston rod and PT1/2 ports, making it a robust actuator for medium-to-heavy linear push/pull tasks.
This specific unit is configured with an FB rear rectangular flange (part F-SC100FB) for rigid end-face mounting. The body length A is 188 mm, and the total extended length is approximately 438 mm. It features an adjustable pneumatic cushion (29 mm length) to decelerate the piston smoothly at stroke ends, protecting the end caps and reducing noise.

Where the Airtac SC100 Standard Cylinder SC100X250FB Is Used
Pallet Stop & Lift Gates
The 3927 N push force at 0.5 MPa easily raises or stops heavy pallets on conveyor lines, providing reliable material flow control.
Press & Clamping Fixtures
Delivers up to 7068 N of clamping force at 0.9 MPa for holding large workpieces during welding, assembly, or machining operations.
Agricultural Equipment Actuation
Operates chutes, diverters, and hopper doors on harvesters or processing equipment, handling dusty conditions with its durable tie-rod construction.
Is the Airtac SC100 Standard Cylinder SC100X250FB the Right Cylinder?
Choose the SC100 bore when your application requires between 3927 N (push at 0.5 MPa) and 7068 N (push at 0.9 MPa). If your force requirement is lower, stepping down to an SC80 bore provides 2513 N at 0.5 MPa in a lighter, more compact package. For higher forces, the SC125 bore offers 6136 N at the same pressure.
For a correct drop-in replacement, match five key points: 100 mm bore, 250 mm stroke, PT1/2 port thread, FB rear flange mounting, and the absence of a magnet. This is a tie-rod cylinder, not an ISO 15552 profile, so dimensional interchangeability is limited to other AirTAC SC100 tie-rod cylinders with the same configuration.
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 SC100X250FB FAQ
At the standard operating pressure of 0.7 MPa, the push force is 5497 N and the pull force is 3681 N. The maximum operating force at 0.9 MPa is 7068 N push. The theoretical maximum at 1.0 MPa is 801 kgf.
Yes, the FB suffix designates a rear rectangular flange mount. The cylinder body is bolted to a machine face via the flange on the rear cap. The accessory code for this flange is F-SC100FB. Ensure the mounting surface is flat and rigid to prevent misalignment.
