About the Airtac SC100 Standard Cylinder SC100X250SFA
The AirTAC SC100X250SFA is a tie-rod double-acting cylinder delivering 3927 N of push force at 0.5 MPa (7068 N at 0.9 MPa). Its 250 mm stroke suits medium-reach clamping and pressing operations, while the 25 mm diameter rod and 29 mm air cushion provide stable deceleration.
This model includes a built-in magnet for direct mounting of CMSG/DMSG/EMSG sensors, plus an FA front rectangular flange (F-SC100FA) for secure panel mounting. The TPU seals and PT1/2 port threads handle standard compressed air at -20 to +70 °C.

Where the Airtac SC100 Standard Cylinder SC100X250SFA Is Used
Automated Press Fitting
Generates 3927 N at 0.5 MPa for pressing bearings, bushings, or pins into housings on assembly lines.
Heavy Part Diverting
The 250 mm stroke and FA flange mount allow secure panel installation to divert 80+ kg packages on conveyor systems.
Clamping & Welding Fixtures
Provides consistent clamping force for large weldments, with magnetic sensors confirming full extension and retraction.
Is the Airtac SC100 Standard Cylinder SC100X250SFA the Right Cylinder?
For higher force, step up to the SC125 bore (6136 N at 0.5 MPa); for a lighter, faster actuator, the SC80 bore offers 2513 N. The 250 mm stroke is well within the 1500 mm maximum for this bore, so no special stroke considerations apply. To replace an existing cylinder, match the 100 mm bore, 250 mm stroke, PT1/2 port thread, FA front flange mounting, and the -S magnet option exactly.
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 SC100X250SFA FAQ
At 0.5 MPa, push force is 3927 N and pull force is 3681 N. At the maximum operating pressure of 0.9 MPa, push force reaches 7068 N. The theoretical maximum at 1.0 MPa is 801 kgf.
Yes. The -S suffix in the model code indicates a built-in magnet, allowing AirTAC CMSG, DMSG, or EMSG reed and solid-state sensors to be clamped directly onto the cylinder barrel for end-of-stroke detection.
