About the Airtac SC80 Standard Cylinder SC80X115STC
The SC80X115STC is an 80 mm bore, 115 mm stroke double-acting pneumatic cylinder delivering a push force of 2513 N at 0.5 MPa and up to 4523 N at 0.9 MPa operating pressure. This model features a 25 mm diameter piston rod with M20x1.5 male threads and an adjustable air cushion length of 28 mm at each end, providing smooth deceleration for mid-stroke positioning tasks.
Configured with a built-in magnet (-S) and centre trunnion mount (TC), the cylinder body length is 182 mm. The magnet allows direct clamping of CMSG/DMSG/EMSG sensors for electrical position feedback, while the trunnion, supplied with the TCM1 bracket, enables the cylinder to pivot during operation, making it ideal for swinging or articulating loads.

Where the Airtac SC80 Standard Cylinder SC80X115STC Is Used
Part Diverter Gates
The centre trunnion mount allows the cylinder body to pivot, making it perfect for actuating diverter gates on conveyor systems where a 115 mm stroke can redirect packages or materials between lanes.
Clamping & Welding Fixtures
With 2513 N of clamping force at standard line pressure and magnetic piston sensing, this cylinder confirms clamp engagement in automated welding or assembly fixtures, ensuring cycle safety.
Articulating Machine Guards
The trunnion pivot and 115 mm stroke suit it for raising and lowering hinged safety guards on industrial machinery, where the sensor confirms the guard is closed before the machine cycle starts.
Is the Airtac SC80 Standard Cylinder SC80X115STC the Right Cylinder?
For applications needing slightly less force, consider stepping down to a 63 mm bore, which provides 1559 N of push at 0.5 MPa. The SC80X115STC is a direct replacement only for an AirTAC SC tie-rod cylinder of identical 80 mm bore, 115 mm stroke, PT port thread, centre trunnion (TC) mounting, and built-in magnet (-S). Always match all five attributes to ensure correct mounting geometry and sensor compatibility. The 115 mm stroke is well within the standard range, so no additional rod support is typically required for purely axial loads.
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 SC80X115STC FAQ
At the standard 0.5 MPa operating pressure, 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. These values are for a double-acting cylinder with a 25 mm rod.
Yes. The 'S' in the model code indicates a built-in magnet on the piston. This allows you to mount AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the cylinder barrel's sensor groove to detect end-of-stroke or intermediate positions.
