About the Airtac SC80 Standard Cylinder SC80X80SFA
The SC80X80SFA delivers 2513 N of push force at 0.5 MPa, making it a strong mid-range actuator for short linear moves. Its 80 mm bore houses a 25 mm diameter rod, providing good rigidity for push/pull tasks.
This model includes a built-in magnet for barrel-mounted sensors and an FA front rectangular flange (F-SC80FA) for secure panel mounting. The adjustable air cushion at each end softens the stroke, and the PT1/4 port threads keep plumbing straightforward.

Where the Airtac SC80 Standard Cylinder SC80X80SFA Is Used
Clamping & Holding
Short 80 mm stroke with front flange mounting suits jigs and fixtures where the cylinder body is bolted to a stationary plate and the rod applies direct clamping force.
Part Ejection
Pushes finished parts off a conveyor or out of a nest. The magnet allows end-of-stroke confirmation via CMSG/DMSG sensors before the next cycle starts.
Press Tool Actuation
Delivers consistent 2513 N push force for light pressing, staking, or forming operations where the cylinder mounts directly to the press frame via the FA flange.
Is the Airtac SC80 Standard Cylinder SC80X80SFA the Right Cylinder?
For higher force in the same bore class, step up to the SC100 (3927 N at 0.5 MPa). If a shorter body is needed, the SC63 offers 1559 N. When replacing, match bore, stroke, PT port thread, FA front flange mount, and the -S magnet option to ensure sensor compatibility. The 80 mm stroke is well within standard limits, so no side-load concerns arise from rod extension alone.
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 SC80X80SFA FAQ
At 0.5 MPa it pushes with 2513 N and pulls with 2268 N. At the maximum operating pressure of 0.9 MPa, push force reaches 4523 N.
Yes. The -S suffix indicates a built-in magnet, so AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors can be clamped directly onto the barrel to detect piston position.
