About the Airtac SC100 Standard Cylinder SC100X300SFA
The SC100X300SFA is a double-acting pneumatic cylinder delivering 3927 N of push force at 0.5 MPa and up to 7068 N at the maximum operating pressure of 0.9 MPa. Its 100 mm bore and 300 mm stroke make it a powerful actuator for medium-to-heavy industrial linear motion tasks, with a 25 mm diameter piston rod and a 29 mm adjustable air cushion at each end to decelerate the load smoothly.
This model includes a built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG sensors to be mounted directly on the tie-rod barrel for non-contact position sensing. The FA front rectangular flange (accessory F-SC100FA) is fitted for secure panel or bulkhead mounting, and the standard PT1/2 port threads and TPU seals suit normal operating temperatures from -20 to +70 °C.

Where the Airtac SC100 Standard Cylinder SC100X300SFA 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 built-in magnet allows end-of-stroke sensors to confirm gate position for interlocked material handling sequences.
Press & Clamping Fixtures
Delivers up to 7068 N of clamping force at 0.9 MPa for holding large workpieces during machining or welding. The front flange mount (F-SC100FA) provides rigid, face-on attachment to a fixture plate.
Bulkhead Actuation
The FA front flange is ideal for mounting through a machine bulkhead or panel, with the 300 mm stroke pushing tooling into a process chamber. Sensor feedback from the magnet confirms full extension and retraction.
Is the Airtac SC100 Standard Cylinder SC100X300SFA the Right Cylinder?
Choose the SC100 bore when your application needs between roughly 2500 N and 7000 N of force at typical plant air pressures. If your load is lighter, stepping down to an SC80 bore saves air and space (2513 N push at 0.5 MPa); for heavier work, the SC125 bore provides 6136 N at the same pressure. At a 300 mm stroke, the 25 mm rod is robust, but any significant side load requires an external guide or a guided cylinder to protect the rod bearing and seals from bending stress. For a direct replacement, match five points: 100 mm bore, 300 mm stroke, PT1/2 port thread, the FA front flange mount, and the -S magnet for sensor compatibility.
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 SC100X300SFA FAQ
At 0.5 MPa (5 bar), the cylinder pushes with 3927 N and pulls with 3681 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 7068 N. The theoretical maximum at 1.0 MPa is 801 kgf.
No. The AirTAC SC series is a tie-rod cylinder that is physically shorter than an ISO 15552 cylinder of the same bore and stroke, so it is not dimensionally interchangeable. You must replace it with another AirTAC SC100 tie-rod cylinder matching the 300 mm stroke, PT1/2 ports, FA front flange mount, and -S magnet option.
