About the Airtac SC100 Standard Cylinder SC100X125SFA
The SC100X125SFA is a double-acting pneumatic cylinder delivering 3927 N of push force at 0.5 MPa (up to 7068 N at 0.9 MPa operating pressure) from a 100 mm bore. With a 125 mm stroke, this tie-rod actuator suits medium-travel clamping, pressing, and material-handling tasks where consistent, repeatable linear motion is required.
This configuration includes a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG sensors, enabling rod-position feedback without external brackets. The FA front rectangular flange (F-SC100FA) allows secure panel or bulkhead mounting. It uses a 25 mm diameter piston rod with M20x1.5 male threads, PT1/2 port connections, and 29 mm of adjustable air cushion at each end to decelerate the piston smoothly.

Where the Airtac SC100 Standard Cylinder SC100X125SFA Is Used
Automated Clamping Fixtures
The 3927 N push force at 0.5 MPa and 125 mm stroke make this cylinder ideal for pneumatic clamping in CNC machining centres or welding jigs. The front flange mount secures the cylinder rigidly to a fixture plate, while the built-in magnet provides end-of-stroke confirmation to the machine controller.
Part Stops & Diverters
Deploy the SC100X125SFA as a heavy-duty part stop on a conveyor line. The 29 mm adjustable cushion absorbs impact from pallets or totes weighing up to several hundred kilograms, and the magnetic piston lets operators add sensors to verify the stop is fully retracted before releasing the next item.
Press-Fit Assembly Stations
With a maximum theoretical force of 801 kgf at 1.0 MPa, this cylinder handles light press-fit assembly of bearings, bushings, or pins. The front flange mounting provides a stable, perpendicular push axis, and the adjustable cushion protects the tooling from shock at the end of the 125 mm pressing stroke.
Is the Airtac SC100 Standard Cylinder SC100X125SFA the Right Cylinder?
Choose the SC100 bore when your application needs roughly 3927 N of push force at standard plant pressure (0.5 MPa). If you can tolerate a smaller envelope, stepping down to an SC80 bore provides 2513 N at 0.5 MPa. For higher force without increasing air pressure, step up to the SC125 bore (6136 N at 0.5 MPa).
For a reliable drop-in replacement, match five key attributes: 100 mm bore, 125 mm stroke, PT1/2 port thread, FA front-flange mounting, and the -S magnet option for sensor compatibility. This SC series is a tie-rod cylinder with a shorter overall body length than an ISO 15552 profile cylinder, so dimensional interchangeability is limited to other AirTAC SC tie-rod cylinders of 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 SC100X125SFA FAQ
At the standard operating pressure of 0.5 MPa, the push force is 3927 N and the pull force (retract) is 3681 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 7068 N. The theoretical maximum at 1.0 MPa is 801 kgf. These values assume a clean, filtered air supply and a static piston.
No. The AirTAC SC series is a tie-rod cylinder with a shorter overall body length than a typical ISO 15552 profile cylinder. It is not dimensionally interchangeable with ISO 15552 standards. For a correct replacement, match the SC100 bore, 125 mm stroke, PT1/2 ports, FA front flange mount, and the -S magnetic piston option to another AirTAC SC tie-rod cylinder.
