About the Airtac SC100 Standard Cylinder SC100X75FB
The SC100X75FB is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining a 100 mm bore with a compact 75 mm stroke. It generates a substantial 3927 N of push force at 0.5 MPa (7068 N at 0.9 MPa), making it a strong mid-range actuator for pressing and clamping tasks.
This model is configured with an FB rear rectangular flange (F-SC100FB) for rigid end-face mounting. It uses a 25 mm diameter piston rod with M20x1.5 threads, PT1/2 ports, and an adjustable air cushion length of 29 mm to decelerate the piston smoothly. The standard TPU seals suit operating temperatures from -20 to +70 °C.

Where the Airtac SC100 Standard Cylinder SC100X75FB Is Used
Material Stops
Provides a firm, controlled stop for pallets or boxes on a conveyor line, using the rear flange to mount securely against a bulkhead.
Clamping Fixtures
Delivers high clamping force for holding parts during welding or assembly, with the short 75 mm stroke ensuring rapid cycle times.
Press Operations
Ideal for light-duty arbor presses or insertion machines where a compact, high-force actuator is needed to push bearings or pins.
Is the Airtac SC100 Standard Cylinder SC100X75FB the Right Cylinder?
Choose the SC100 bore when your application needs around 4000 N of force at standard shop air pressure. If you require a lighter, more compact actuator, stepping down to the SC80 bore provides 2513 N at 0.5 MPa, which may be sufficient for lower-load tasks. For higher force demands, the SC125 bore delivers 6136 N at the same pressure.
To ensure a correct replacement, match five key points: the 100 mm bore, 75 mm stroke, PT port thread, FB rear flange mounting, and the absence of a magnet. This cylinder is a tie-rod design and is not dimensionally interchangeable with ISO 15552 profile cylinders.
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 SC100X75FB FAQ
At 0.7 MPa operating pressure, the SC100 bore generates a theoretical push force of 5497 N. The pull force on the retract stroke is 3681 N at 0.5 MPa, due to the area reduction from the 25 mm piston rod.
No. The AirTAC SC series is a tie-rod cylinder with a shorter overall body length than a typical ISO 15552 cylinder. It will only drop-in replace another SC series cylinder of the same bore, stroke, and mounting configuration. Always verify the body length 'A' (188 mm for the SC100) plus your 75 mm stroke for total extended length.
