About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X35STC
The AirTAC SC125X35STC is a double-acting tie-rod cylinder engineered for short-stroke, high-force applications. With a 125 mm bore and 35 mm stroke, it generates a substantial 6136 N of push force at 0.5 MPa (11045 N at the 0.9 MPa maximum operating pressure), making it a powerful actuator for compact spaces.
This model features a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG sensors, enabling precise end-of-stroke detection. The TC suffix denotes a centre trunnion mount, supplied with the TCM1 bracket (F-SC125TC), which allows the cylinder to pivot and is ideal for swinging or articulating loads. The 32 mm rod with M27x2 thread and 28 mm adjustable air cushion ensure robust, decelerated end-of-stroke performance.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X35STC Is Used
Clamping & Stamping
The 6136 N force at 0.5 MPa makes this cylinder perfect for heavy-duty clamping, stamping, or pressing operations where a short, powerful stroke is needed to secure workpieces.
Material Ejection
With a 35 mm stroke and high force, it can reliably eject heavy parts or scrap from a die or fixture, and the built-in magnet allows sensors to confirm each ejection cycle.
Pivoting Conveyor Gate
The centre trunnion mount allows the cylinder to swing, making it suitable for actuating a heavy diverter gate on a conveyor system, directing large or bulky packages.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X35STC the Right Cylinder?
Select the SC125 bore when your application requires a push force between 6136 N and 11045 N. If your force requirement is lower, consider stepping down to the SC100 bore, which provides 3927 N at 0.5 MPa. For higher forces, the SC160 bore delivers 10053 N at the same pressure.
For a direct replacement, match these five points: 125 mm bore, 35 mm stroke, PT port thread, centre trunnion (TC) mount, and the built-in magnet for sensor compatibility. This SC cylinder is a tie-rod design and is not dimensionally interchangeable with ISO 15552 profile cylinders, though its 125 mm bore falls under the ISO 6430 class for larger 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 SC125X35STC FAQ
At 0.5 MPa, 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 forces are theoretical and based on a 125 mm bore with a 32 mm rod.
No. The AirTAC SC series is a tie-rod cylinder and is physically shorter than a standard ISO 15552 cylinder. It is not dimensionally interchangeable. It is a direct replacement only for another AirTAC SC125 tie-rod cylinder with matching bore, stroke, PT ports, TC mount, and magnet.
