About the Airtac SC80 Standard Cylinder SC80X125SFA
The AirTAC SC80X125SFA is a double-acting single-rod pneumatic cylinder delivering 2513 N push force at 0.5 MPa (4523 N at 0.9 MPa). Its 80 mm bore and 125 mm stroke suit medium-duty clamping, pressing, and material-handling tasks where a compact tie-rod body is preferred.
This model includes a built-in magnet (-S) for barrel-mounted CMSG/DMSG/EMSG sensors, and the FA front rectangular flange (F-SC80FA) for secure panel mounting on the rod side. The 25 mm diameter rod, PT3/8 ports, and 28 mm adjustable air cushion provide reliable deceleration. Body length A is 182 mm, giving a total extended length of approximately 307 mm.

Where the Airtac SC80 Standard Cylinder SC80X125SFA Is Used
Conveyor Diverting
The 125 mm stroke and 2513 N push force reliably shift packages or product carriers between conveyor lanes in automated sortation systems.
Panel Clamping
Front flange mounting and sensor-ready magnet make it ideal for clamping fixtures on assembly panels, confirming rod position before the next cycle.
Press-Fit Assembly
With 4523 N of force at 0.9 MPa, this cylinder handles light press-fit insertions and riveting operations on benchtop automation cells.
Is the Airtac SC80 Standard Cylinder SC80X125SFA the Right Cylinder?
Choose the SC80 bore when your application needs around 2513 N at 0.5 MPa. For lighter loads, the SC63 bore offers 1559 N at the same pressure, while the SC100 steps up to 3927 N for heavier work. Always match bore, 125 mm stroke, PT3/8 port thread, FA front flange mount, and the built-in magnet when replacing an existing SC80X125SFA.
At 125 mm stroke, the rod bearing is well-supported, but any side load should still be managed with an external guide or linear rail to prevent rod bending and premature seal wear.
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 SC80X125SFA FAQ
At 0.5 MPa, it produces 2513 N pushing and 2268 N pulling. At the maximum operating pressure of 0.9 MPa, the push force reaches 4523 N. The theoretical maximum at 1.0 MPa is 513 kgf.
Yes, the SC80X125SFA is backward-compatible with a non-magnet SC80X125FA. The added magnet lets you clamp CMSG/DMSG/EMSG sensors to the barrel for position feedback, without changing the mounting footprint or port connections.
