About the Airtac SC100 Standard Cylinder SC100X125
The SC100X125 is a 100 mm bore double-acting pneumatic cylinder with a 125 mm standard stroke, delivering a push force of 3927 N at 0.5 MPa (7068 N at 0.9 MPa). Its 25 mm diameter piston rod and PT1/2 ports suit medium-to-heavy linear actuation tasks where a compact tie-rod body is preferred.
With a body length A of 188 mm and an adjustable air cushion of 29 mm, this cylinder decelerates end-of-stroke loads effectively. The SC series is a genuine AirTAC tie-rod cylinder, shorter than an ISO 15552 profile, and is built for filtered air operation from 0.15 to 1.0 MPa.

Where the Airtac SC100 Standard Cylinder SC100X125 Is Used
Part Transfer
The 125 mm stroke and 3927 N push force at 0.5 MPa move heavy components between conveyor stations or into assembly nests reliably.
Press-Fit Assembly
With 7068 N of force available at 0.9 MPa, this cylinder can press bearings, bushings, or pins into housings in semi-automated fixtures.
Clamping & Holding
Delivers consistent clamping force for machining centres or welding jigs. Note: an external pilot-operated check valve is required to hold position if air pressure is lost.
Is the Airtac SC100 Standard Cylinder SC100X125 the Right Cylinder?
Choose the SC100 bore when the 50 mm bore’s 982 N at 0.5 MPa is insufficient but a 125 mm bore (6136 N) would be oversized. For this 125 mm stroke, the standard tie-rod construction handles axial loads well; if the application involves side loads, add an external linear guide to protect the rod bearing and piston seals.
To replace an existing cylinder, match five points: 100 mm bore, 125 mm stroke, PT1/2 port thread, basic (no accessory) mounting, and no magnet. The SC is not dimensionally interchangeable with ISO 15552 cylinders, so verify body length A (188 mm) and mounting hole positions.
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 SC100X125 FAQ
At 0.5 MPa the push force is 3927 N, and the pull force 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.
No. The SC is a tie-rod cylinder that is physically shorter than an ISO 15552 profile cylinder, so mounting dimensions and body length (188 mm) differ. It is a direct replacement only for another AirTAC SC100 tie-rod cylinder with matching bore, stroke, port thread, and mounting.
