About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X200TC
The SC125X200TC is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining a 125 mm bore with a 200 mm stroke. At 0.5 MPa it generates 6136 N of push force and 5734 N on the pull stroke, scaling up to a powerful 11045 N at the maximum operating pressure of 0.9 MPa. The piston rod measures 32 mm in diameter with an M27x2 knuckle thread, and the cylinder body length A is 203 mm.
This specific model is factory-configured with a TC centre trunnion mount, supplied together with the TCM1 bracket (accessory code F-SC125TC), allowing the cylinder to pivot freely for swinging or articulating loads. It features PT1/2 ports, adjustable air cushioning with a 28 mm cushion length, and operates on filtered air within a -20 to +70 °C temperature range using standard TPU seals.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X200TC Is Used
Heavy-Duty Clamping & Fixturing
Delivers up to 11045 N of clamping force at 0.9 MPa for securely holding large weldments, castings, or structural components during machining or assembly processes.
Pivoting Conveyor Diverter Gates
The TC centre trunnion mount allows the cylinder to pivot as it actuates heavy diverter gates or flippers on wide conveyor lines, sorting large packages or bulk materials.
Industrial Press & Forming Assist
With 6136 N of force at standard shop air, it powers assist cylinders on mechanical presses or operates heavy-duty bending and forming fixtures in metal fabrication.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X200TC the Right Cylinder?
Choose the SC125 bore when your application requires a force between roughly 5000 N and 11000 N; if you can work with a smaller envelope, the SC100 bore delivers 3927 N at 0.5 MPa and uses a 25 mm rod. For this 200 mm stroke, a centre trunnion mount is ideal for applications where the cylinder body needs to pivot, but always ensure the load is guided externally to prevent damaging side loads on the rod bearings. For a direct replacement, match five key attributes: 125 mm bore, 200 mm stroke, PT port thread, TC centre trunnion mounting, and the absence of a built-in magnet.
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 SC125X200TC FAQ
At 0.7 MPa (7 bar) operating pressure, the theoretical push force on the 125 mm bore is 8590 N. The pull force on the rod side, accounting for the 32 mm rod area, is 5734 N.
No. The AirTAC SC series is a tie-rod cylinder that is physically shorter than a comparable ISO 15552 profile cylinder, so the mounting dimensions and overall length are not interchangeable. It is a direct replacement only for another AirTAC SC tie-rod cylinder matching the same bore, stroke, PT port, and TC trunnion mount.
