About the Airtac SC100 Standard Cylinder SC100X75FA
The SC100X75FA is a 100 mm bore, 75 mm stroke double-acting tie-rod cylinder delivering 3927 N push force at 0.5 MPa (7068 N at 0.9 MPa). Its 25 mm rod and PT1/2 ports suit medium-duty clamping and pressing tasks where a compact 188 mm body length (A dimension) plus stroke fits tight machine envelopes.
This model comes with a front rectangular flange (FA) pre-mounted for rigid panel or bulkhead installation. The adjustable air cushion (29 mm) decelerates the piston smoothly at end-of-stroke, reducing impact noise. As a genuine AirTAC SC series unit, it uses TPU/NBR seals for standard -20 to +70 °C operation and filtered air at 40 µm.

Where the Airtac SC100 Standard Cylinder SC100X75FA Is Used
Press-Fit Assembly
The 3927 N push at 0.5 MPa inserts bearings, bushings, or pins into housings with controlled force. The front flange mount holds the cylinder rigidly against the press frame.
Product Gate / Diverter
A short 75 mm stroke actuates a gate or diverter arm on a conveyor line. The tie-rod design handles repetitive cycling in packaging and sortation systems.
Clamping Fixture
Delivers up to 7068 N at 0.9 MPa for holding workpieces during machining or welding. The FA flange bolts directly to a fixture plate for accurate alignment.
Is the Airtac SC100 Standard Cylinder SC100X75FA the Right Cylinder?
Choose the SC100 bore when your application needs around 3900 N at 0.5 MPa. If force requirements drop below 2500 N, stepping down to the SC80 (2513 N at 0.5 MPa) saves space and air consumption. For higher force, the SC125 delivers 6136 N at the same pressure.
This 75 mm stroke is well within the 1500 mm maximum standard stroke for bore 100, so it is a stock configuration. To replace an existing cylinder, match five points: 100 mm bore, 75 mm stroke, PT port thread, FA front flange mounting (F-SC100FA), and confirm whether a magnet is needed (this code has no -S magnet).
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 SC100X75FA FAQ
At 0.5 MPa the push force is 3927 N and pull force is 3681 N. At 0.7 MPa push reaches 5497 N, and at the maximum operating pressure of 0.9 MPa it produces 7068 N. The theoretical force at 1.0 MPa is 801 kgf.
No. The SC series is a tie-rod cylinder, not an ISO 15552 profile cylinder. It is shorter than an equivalent ISO 15552 cylinder and is not dimensionally interchangeable. Replace only with another AirTAC SC tie-rod cylinder matching bore, stroke, port thread, and FA front flange mounting.
