About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X150
The AirTAC SC125X150 is a double-acting tie-rod cylinder delivering 6136 N of push force at 0.5 MPa, rising to 11045 N at the maximum operating pressure of 0.9 MPa. This 125 mm bore model features a robust 32 mm piston rod with an M27x2 knuckle thread and PT1/2 ports, making it a powerful actuator for medium-stroke industrial applications.
With a 150 mm stroke and a body length A of 203 mm, this cylinder belongs to the ISO 6430 class for big-bore cylinders. Its 28 mm adjustable air cushion decelerates the piston smoothly at end-of-stroke, protecting the end caps and reducing noise in high-cycle operations.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X150 Is Used
Heavy Machinery Actuation
Provides the high force needed for lifting and tilting mechanisms on agricultural and construction equipment, operating reliably with filtered air.
Palletising and Staging
Ideal for palletisers and transfer stations where a 150 mm stroke is used to push heavy totes or boxes onto a conveyor line with controlled cushioning.
Clamping and Forming Presses
Delivers up to 11045 N of force for holding workpieces in heavy-duty welding fixtures or operating a forming die in a small press.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X150 the Right Cylinder?
Select the SC125 when your application requires a force step up from the SC100 (3927 N at 0.5 MPa). If your load is lighter and speed is a priority, the smaller SC80 (2513 N at 0.5 MPa) may offer a more compact solution. For a direct replacement, match five key points: 125 mm bore, 150 mm stroke, PT port thread, basic mounting, and the absence of a magnet.
At a 150 mm stroke, the 32 mm rod is well-supported within the bearing for most axial loads. However, if the application introduces any side load, consider an external guide rail to prevent rod bending and premature seal 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 SC125X150 FAQ
At the standard operating pressure of 0.7 MPa, the push force is 8590 N and the pull force is 5734 N. The maximum push force at 0.9 MPa is 11045 N. The theoretical maximum at 1.0 MPa is 1251 kgf.
No. The SC series is a tie-rod cylinder that is shorter in overall length than a comparable ISO 15552 profile cylinder. It is dimensionally interchangeable only with another AirTAC SC tie-rod cylinder of the same bore and stroke, or an equivalent tie-rod design matching its port and mounting specifications.
