About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X80TC
The SC125X80TC is a double-acting pneumatic cylinder with a 125 mm bore and 80 mm stroke, supplied with a centre trunnion (TC) mount for pivoting applications. At 0.5 MPa it generates 6136 N push force and 5734 N pull force, rising to 11045 N push at the 0.9 MPa maximum operating pressure.
This model uses a 32 mm diameter piston rod with M27x2 male threads and PT1/2 ports. The adjustable air cushion is 28 mm long, and the body length A is 203 mm. The TC mount includes the TCM1 trunnion bracket (order reference F-SC125TC), allowing the cylinder to swing as the load articulates.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X80TC Is Used
Conveyor Diverter Gates
The centre trunnion mount lets the cylinder pivot as it actuates a diverter gate, directing packages or bulk material on a conveyor line with 6136 N of push force at 0.5 MPa.
Clamping & Welding Fixtures
Delivers 11045 N of clamping force at 0.9 MPa for heavy weldments or machining fixtures, with the trunnion mount absorbing angular misalignment during clamp/unclamp cycles.
Pivoting Press Mechanisms
Ideal for toggle presses and articulating press arms where the cylinder body must swing. The 32 mm rod and 28 mm cushion handle high-cycle pressing with controlled deceleration.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X80TC the Right Cylinder?
Choose the SC125 bore when your application needs roughly 6100 N of push force at standard shop air. If you can work with about 3900 N, stepping down to the SC100 bore saves space and air consumption. For strokes of 300 mm or more on this 32 mm rod, check side-load conditions carefully—an external guide or guided cylinder prevents rod-bearing bending and premature seal wear.
When replacing an existing cylinder, match five points: 125 mm bore, 80 mm stroke, PT1/2 port thread, centre trunnion (TC) mounting with the TCM1 bracket, and confirm whether a magnet (-S) is needed. The SC series is a tie-rod design and is not dimensionally interchangeable with ISO 15552 profile cylinders.
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 SC125X80TC FAQ
At 0.7 MPa (7 bar) the SC125 bore generates 8590 N of push force and 5734 N of pull force. At the maximum operating pressure of 0.9 MPa, push force reaches 11045 N. The theoretical maximum at 1.0 MPa is 1251 kgf.
The SC125X80TC ships with the centre trunnion (TC) mount and TCM1 bracket. If your application requires a rear clevis, order the SC125X80CA (single clevis) or SC125X80CB (double clevis) variant instead. The mounting is fixed at the time of manufacture—retrofitting a different mount is not recommended.
