About the Airtac SC100 Standard Cylinder SC100X125STC
The AirTAC SC100X125STC is a double-acting single-rod pneumatic cylinder delivering a push force of 3927 N at 0.5 MPa (7068 N at 0.9 MPa). With a 100 mm bore and 125 mm stroke, this model is built for robust clamping, pressing, and material-handling tasks. The built-in magnet (-S) allows direct mounting of CMSG/DMSG/EMSG sensors on the tie-rod barrel for reliable end-of-stroke detection.
This configuration includes a centre trunnion mount (TC), supplied with the TCM1 bracket (F-SC100TC), enabling the cylinder to pivot during operation—ideal for swinging or articulating loads. The 25 mm diameter piston rod and 29 mm adjustable air cushion provide smooth deceleration. Standard PT ports (PT1/2) and TPU seals complete the package, suitable for ambient temperatures from -20 to +70 °C.

Where the Airtac SC100 Standard Cylinder SC100X125STC Is Used
Conveyor Diverters & Stops
The 3927 N push force at 0.5 MPa easily actuates heavy-duty conveyor gates and pallet stops. The trunnion mount allows the cylinder to swing as the diverter arm moves through its arc.
Waste Compaction & Baling
Delivers up to 7068 N of thrust at 0.9 MPa for compacting recyclables or waste material. The magnetic piston enables sensor feedback to confirm full compaction stroke before cycling.
Welding & Clamping Fixtures
Ideal for heavy-duty welding jigs where the cylinder body must pivot out of the way for part loading. The centre trunnion mount handles the pivoting action, while the 25 mm rod resists side loads.
Is the Airtac SC100 Standard Cylinder SC100X125STC the Right Cylinder?
Select the SC100 when your application needs roughly 3927 N of push force at standard plant pressure. If you require more force, consider stepping up to the SC125 (6136 N at 0.5 MPa); for a lighter, more compact solution, the SC80 provides 2513 N. This 125 mm stroke is standard and well within the 1500 mm maximum for this bore.
For replacement, match five key points: 100 mm bore, 125 mm stroke, the PT1/2 port thread, the centre trunnion mounting kit (F-SC100TC), and the -S magnetic piston for sensor compatibility. Always verify the tie-rod body length (A=188 mm) and mounting dimensions against your existing setup.
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 SC100X125STC FAQ
At the standard operating pressure of 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 increases to 7068 N. The theoretical maximum force at 1.0 MPa is 801 kgf.
No. The AirTAC SC series is a tie-rod cylinder and is physically shorter than a standard ISO 15552 profile cylinder. It is not dimensionally interchangeable. Replace only with another AirTAC SC tie-rod cylinder matching the 100 mm bore, 125 mm stroke, PT ports, TC trunnion mount, and -S magnet option.
