About the Airtac SC80 Standard Cylinder SC80X50SFA
The SC80X50SFA is a double-acting pneumatic cylinder delivering 2513 N of push force at 0.5 MPa (4523 N at 0.9 MPa). Its 50 mm stroke is ideal for short clamping, ejecting, and pressing tasks where a compact extended length of approximately 232 mm fits tight stations.
This model includes a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG sensors, enabling rod-position feedback without external brackets. The FA front rectangular flange (F-SC80FA) bolts rigidly to the rod-end surface, and the 25 mm diameter rod with PT3/8 ports handles rapid cycling at 30-800 mm/s.

Where the Airtac SC80 Standard Cylinder SC80X50SFA Is Used
Short-Stroke Clamping
The 50 mm stroke with 2513 N force securely clamps workpieces in CNC fixtures and welding jigs, with the front flange providing rigid, aligned mounting.
Part Ejection & Sorting
Fast 30-800 mm/s cycling pushes parts off conveyors or into lanes. The built-in magnet allows end-of-stroke sensing to confirm each ejection cycle.
Compact Press Operations
Delivers up to 4523 N at 0.9 MPa for light press-fit assembly, riveting, or staking in automated cells where a short, stiff cylinder is required.
Is the Airtac SC80 Standard Cylinder SC80X50SFA the Right Cylinder?
For higher force in the same mounting footprint, step up to the SC100 bore (3927 N at 0.5 MPa). If space is tight and 628 N suffices, the SC40 bore is a smaller alternative. Match replacements on five points: 80 mm bore, 50 mm stroke, PT port thread, FA front flange mounting, and the -S magnet for sensor compatibility. Any substitute must replicate the F-SC80FA flange pattern and the magnetic piston to retain sensor function.
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 SC80X50SFA FAQ
At 0.5 MPa, push force is 2513 N and pull force is 2268 N. At the maximum operating pressure of 0.9 MPa, push force reaches 4523 N. The theoretical maximum at 1.0 MPa is 513 kgf.
Yes. The -S suffix denotes a built-in magnet, so AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors clamp directly onto the tie-rod barrel to detect piston position. Without the -S option, the cylinder has no magnet and these sensors will not function.
