About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X230S
The AirTAC SC125X230S is a double-acting tie-rod cylinder delivering 6136 N of push force at 0.5 MPa (11045 N at the maximum operating pressure of 0.9 MPa). Its 230 mm stroke is well within the 1500 mm maximum standard stroke for the 125 mm bore, making it a robust off-the-shelf choice for medium-travel linear actuation.
This model features a 32 mm diameter piston rod with an M27x2 knuckle thread and a 28 mm adjustable air cushion at each end. The built-in magnet (-S suffix) allows CMSG, DMSG, or EMSG reed and solid-state sensors to be clamped directly onto the tie-rod barrel for reliable, non-contact position sensing.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X230S Is Used
Pallet Transfer & Stops
Provides the high force needed to lift, stop, or transfer heavy pallets on roller conveyors, with the magnet enabling precise end-of-stroke confirmation.
Heavy Clamping & Fixturing
Delivers over a tonne of clamping force at 0.9 MPa for securing large weldments or castings during machining or assembly processes.
Baler & Compactor Ejection
The 230 mm stroke ejects compacted material bales from large recycling balers, with sensors confirming full extension and retraction cycles.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X230S the Right Cylinder?
Select the SC125 when your application requires a force class above the SC100 (3927 N at 0.5 MPa) but below the SC160 (10053 N at 0.5 MPa). The 230 mm stroke is a standard length, ensuring fast availability. For replacement, match five points: 125 mm bore, 230 mm stroke, PT port thread, the built-in magnet (-S), and the basic mounting configuration.
At this stroke length, the 32 mm rod provides good column strength, but any significant side load should be managed with an external linear guide or a guided cylinder to prevent rod bearing wear and bending.
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 SC125X230S 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. The theoretical maximum force at 1.0 MPa is 1251 kgf.
Yes. The -S suffix in the model code SC125X230S indicates a built-in magnet is installed on the piston. This allows you to clamp compatible CMSG, DMSG, or EMSG sensors directly onto the cylinder's tie-rod barrel to detect piston position without additional brackets.
