About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X100FB
The AirTAC SC125X100FB is a double-acting tie-rod cylinder delivering 6136 N of push force at 0.5 MPa (11045 N at the 0.9 MPa maximum operating pressure). With a 100 mm stroke and a robust 32 mm piston rod, this ISO 6430 class cylinder is built for heavy linear actuation where space is constrained.
This model is configured with an FB rear rectangular flange (accessory F-SC125FB) for rigid end-face mounting. The adjustable pneumatic cushion (28 mm length) decelerates the piston smoothly, and the standard PT1/2 port threads ensure straightforward pneumatic connections. Operating temperature range is -20 to +70 °C with the default TPU seals.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X100FB Is Used
Heavy Material Stops
Stops and positions heavy pallets or steel components on conveyor lines, leveraging the 11045 N max force for reliable holding against impact.
Press-Fit Assembly
Provides the high, controlled force needed for pressing bearings, bushings, or pins into housings in automated assembly cells.
Clamping Large Workpieces
Acts as a powerful clamp in welding fixtures or machining centers, securing large fabrications with consistent, adjustable pressure.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X100FB the Right Cylinder?
Choose the SC125 bore when your application needs between 6136 N (push at 0.5 MPa) and 11045 N (push at 0.9 MPa). If your force requirement is lower, stepping down to the SC100 bore provides 3927 N at 0.5 MPa, offering a more compact and economical solution. For higher forces, consider the SC160 bore.
To ensure a correct replacement, match five key points: 125 mm bore, 100 mm stroke, PT port thread, FB rear flange mounting, and the absence of a magnet. The SC series is a tie-rod cylinder 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 AIRTAC SC125-160 Standard Cylinder SC125X100FB FAQ
At the standard 0.5 MPa operating pressure, the push force is 6136 N and the pull force is 5734 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 11045 N. These values are based on the 125 mm bore and 32 mm rod diameter.
No. The AirTAC SC series is a tie-rod cylinder, which is shorter in overall length than a comparable ISO 15552 profile cylinder. The mounting dimensions and body length (A=203 mm) are different. It is a direct replacement only for another AirTAC SC125 tie-rod cylinder with matching stroke, port, and FB mounting.
