About the Airtac SC100 Standard Cylinder SC100X125SFB
The SC100X125SFB is a double-acting pneumatic cylinder delivering 3927 N of push force at 0.5 MPa and up to 7068 N at 0.9 MPa, making it a robust actuator for medium-to-heavy industrial tasks. This 100 mm bore model features a 25 mm diameter piston rod, PT1/2 ports, and a 29 mm adjustable air cushion at each end to decelerate the load smoothly.
This specific configuration includes a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG sensors, and an FB rear rectangular flange (F-SC100FB) for secure end-face mounting. With a body length of 188 mm and a 125 mm standard stroke, it operates reliably on filtered air within a -20 to +70 °C range using its standard TPU seals.

Where the Airtac SC100 Standard Cylinder SC100X125SFB Is Used
Pallet Stop & Lift Gates
The 3927 N push force at 0.5 MPa easily raises or stops heavy pallets on conveyor lines. The rear FB flange allows secure mounting to a bulkhead at the end of a transfer station.
Press & Clamping Fixtures
Delivers up to 7068 N of clamping force at 0.9 MPa for holding large workpieces during welding or machining. The built-in magnet provides end-of-stroke confirmation via CMSG sensors.
Material Handling Pushers
With a 125 mm stroke, this cylinder is ideal for diverting heavy boxes or components off a main line. The adjustable cushioning prevents impact damage when pushing high-inertia loads.
Is the Airtac SC100 Standard Cylinder SC100X125SFB the Right Cylinder?
Select the SC100 bore when your application requires a push force between 3927 N (at 0.5 MPa) and 7068 N (at 0.9 MPa). If you need a higher force, step up to the SC125, which offers 6136 N at 0.5 MPa. For a lighter, more compact solution, the SC80 provides 2513 N at the same pressure. Always match the bore, 125 mm stroke, PT1/2 port, FB mounting, and the -S magnet when replacing this unit.
For this 125 mm stroke, the 25 mm rod is well-supported within the standard stroke range. However, if the load creates a significant side force, an external guide rail is recommended to prevent rod bearing wear and ensure linear motion stability.
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 SC100X125SFB 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 push force at 0.9 MPa is 7068 N. These forces are theoretical and assume a clean, filtered air supply.
This is a direct replacement for any AirTAC SC100X125 tie-rod cylinder that also uses a built-in magnet (-S), an FB rear flange mount, and PT1/2 ports. It is not dimensionally interchangeable with ISO 15552 profile cylinders, so verify the body length (188 mm + stroke) and mounting pattern match your existing setup.
