About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X125S
The SC125X125S is a robust double-acting tie-rod cylinder delivering a push force of 6136 N at 0.5 MPa and up to 11045 N at 0.9 MPa. Its 125 mm stroke falls well within the standard range for the 125 mm bore, making it a readily available configuration for moderate linear travel.
This model includes a built-in magnet (-S suffix), allowing direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors on the barrel for contactless position detection. The 32 mm diameter piston rod and PT1/2 ports provide ample flow for reliable cycling in heavy industrial tasks.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X125S Is Used
Heavy Press & Clamping
Generates over 11000 N of force at 0.9 MPa, ideal for powerful clamping fixtures, small forming presses, and static material hold-down operations in metal fabrication.
Part Transfer & Ejection
The 125 mm stroke and magnet sensors provide precise, monitored positioning for transferring heavy components between conveyor lines or ejecting parts from assembly nests.
Palletising & Logistics
Delivers the high force needed for pallet stackers and layer-forming pushers, with sensor feedback ensuring accurate, repeatable motion in automated warehouse systems.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X125S the Right Cylinder?
For higher force requirements, stepping up to the SC160 bore raises push force to 10053 N at 0.5 MPa, while the SC100 bore offers 3927 N if a lighter, more compact cylinder is sufficient. When replacing an existing unit, match all five key points: 125 mm bore, 125 mm stroke, PT port thread, the built-in magnet (-S), and the basic mounting configuration to ensure drop-in compatibility.
Although this is a standard stroke, the 32 mm rod is robust, but any side load must be managed. For applications where the rod may experience lateral forces, consider an external linear guide or a guided cylinder to protect the rod bearing and seals from premature wear.
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 SC125X125S 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.
Yes. The -S suffix in the model code SC125X125S indicates a built-in magnet on the piston. This allows you to clamp AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the tie-rod barrel for end-of-stroke or intermediate position sensing without any additional brackets.
