About the Airtac SC80 Standard Cylinder SC80X80STC
The SC80X80STC is an 80 mm bore, 80 mm stroke double-acting pneumatic cylinder delivering 2513 N of push force at 0.5 MPa. It features a 25 mm diameter piston rod, PT3/8 ports, and a 28 mm adjustable air cushion at each end to decelerate the piston smoothly, reducing end-of-stroke impact.
This model is factory-configured with a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, and a centre trunnion (TC) mount that includes the TCM1 bracket (F-SC80TC). The trunnion allows the cylinder to pivot, making it ideal for swinging or articulating loads. The body length A is 182 mm, giving a compact footprint for its force class.

Where the Airtac SC80 Standard Cylinder SC80X80STC Is Used
Part Orientation on Conveyors
The pivoting action of the centre trunnion mount combined with the 80 mm stroke makes this cylinder suitable for flippers or gates that divert packages on a conveyor line.
Clamp and Weld Fixtures
Delivers a firm 2513 N clamping force at 0.5 MPa. The magnetic piston allows end-of-stroke sensing to confirm the clamp is fully engaged before a robotic weld cycle begins.
Chute or Hopper Door Actuation
The trunnion mount handles the arcing motion of a discharge door. The 28 mm cushion absorbs the shock of the door slamming shut, extending the cylinder's service life in dusty environments.
Is the Airtac SC80 Standard Cylinder SC80X80STC the Right Cylinder?
Choose the SC80 for applications needing around 2513 N of force at standard plant pressure. If your load is lighter, stepping down to a 63 mm bore saves space and air, as it provides 1559 N at 0.5 MPa. For heavier loads, the 100 mm bore offers 3927 N. The 80 mm stroke is a standard length within this series.
For a direct replacement, match these five points exactly: 80 mm bore, 80 mm stroke, PT port thread, centre trunnion (TC) mounting with the F-SC80TC bracket, and the built-in magnet (-S) for sensor compatibility. This tie-rod cylinder is shorter than an ISO 15552 profile and is not dimensionally interchangeable with them.
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 SC80 Standard Cylinder SC80X80STC FAQ
At 0.5 MPa, the push force is 2513 N and the pull force is 2268 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 4523 N. The theoretical maximum force at 1.0 MPa is 513 kgf.
Yes. The 'S' in the model code SC80X80STC signifies a built-in magnet on the piston. This allows you to clamp AirTAC CMSG, DMSG, or EMSG reed and solid-state sensors directly onto the barrel's tie-rod slots to detect piston position.
