About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X450
The AirTAC SC125X450 is a double-acting tie-rod cylinder delivering 6136 N of push force at 0.5 MPa and up to 11045 N at 0.9 MPa operating pressure. With a 125 mm bore and 450 mm stroke, this model is built for heavy-duty linear applications requiring substantial force over a mid-range travel distance.
This cylinder features a robust 32 mm piston rod with M27x2 threads and an adjustable air cushion of 28 mm at each end to decelerate high-inertia loads smoothly. The body length A is 203 mm, and the total extended length is approximately 653 mm. It is an ISO 6430 class cylinder, suitable for demanding industrial environments with a standard operating temperature range of -20 to +70 °C using TPU seals.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X450 Is Used
Heavy Press Tool Actuation
Provides the high force (up to 11045 N) needed to operate clamping fixtures and forming tools in metal fabrication presses with a 450 mm stroke.
Pallet Transfer Systems
Delivers the robust push/pull force for transferring heavy pallets or large components between conveyor lines in automated logistics centers.
Industrial Compactor Feed
Powers the feed gate on waste or recycling compactors, reliably moving dense material into the compaction chamber with a 450 mm linear action.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X450 the Right Cylinder?
Select the SC125X450 when your application requires roughly 6000 N of force at standard plant pressure. If your load is lighter and you can accept a smaller footprint, stepping down to the SC100 bore reduces the push force to 3927 N at 0.5 MPa. For strokes of 450 mm, ensure the rod is not subjected to significant side loading; an external guide or a guided cylinder is recommended to prevent rod bending and premature bearing wear.
For a direct replacement, match five key points: the 125 mm bore, the 450 mm stroke, the PT port thread, the basic (no bracket) mounting configuration, and the absence of a built-in magnet. This ensures a drop-in fit for another AirTAC SC series tie-rod cylinder.
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 SC125X450 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. The theoretical maximum force at 1.0 MPa is 1251 kgf.
No. The AirTAC SC series is a tie-rod cylinder and is shorter than an ISO 15552 cylinder, so it is not dimensionally interchangeable. It is an ISO 6430 class cylinder for the 125 mm bore. You should only replace it with another AirTAC SC125 cylinder with the same stroke, port thread, and mounting.
