About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X210STC
The AirTAC SC125X210STC is a robust double-acting pneumatic cylinder delivering 6136 N of push force and 5734 N of pull force at 0.5 MPa operating pressure. With a 210 mm stroke, this model features a 32 mm diameter piston rod and an ISO 6430 class tie-rod construction, making it suitable for heavy-duty linear applications requiring substantial force.
This configuration includes a built-in magnet (S suffix) for direct mounting of CMSG, DMSG, or EMSG sensors, enabling precise end-of-stroke detection. The TC suffix denotes a centre trunnion mount, supplied with the TCM1 bracket (F-SC125TC), which allows the cylinder body to pivot, ideal for swinging or articulating loads. The adjustable air cushion at each end is 28 mm, effectively decelerating the piston to reduce impact and noise.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X210STC Is Used
Conveyor Diverters
The 6136 N push force at 0.5 MPa powerfully actuates heavy-duty diverters and gates in material handling systems, reliably redirecting large packages or pallets.
Clamping & Pressing
Ideal for industrial clamping fixtures and light-duty presses, where the high force output securely holds large workpieces during machining or assembly processes.
Pivoting Machinery
The centre trunnion mount allows the cylinder to swing, making it perfect for actuating pivoting arms, tilting hoppers, or dump mechanisms on heavy equipment.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X210STC the Right Cylinder?
Select the SC125 bore when your application demands push forces in the 6000 N range at standard plant pressure. For a step down in force, the SC100 bore provides 3927 N at 0.5 MPa, while stepping up to the SC160 bore offers 10053 N. This 210 mm stroke is well within the 1500 mm maximum standard stroke for the 125 mm bore. For strokes of this length, ensure the load is guided to prevent side-load bending on the 32 mm rod. When replacing, match the bore, stroke, PT port thread, centre trunnion mount (TC), and the built-in magnet (-S) to ensure a drop-in fit for an existing AirTAC SC cylinder.

- ✓ 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 SC125X210STC 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 'TC' suffix means the cylinder is supplied with the TCM1 trunnion mounting bracket (part code F-SC125TC). This allows the cylinder body to pivot during operation.
