About the Airtac SC80 Standard Cylinder SC80X50FA
The AirTAC SC80X50FA is a double-acting pneumatic cylinder with an 80 mm bore and a 50 mm stroke, supplied with a front rectangular flange (FA) for rigid panel mounting. At 0.5 MPa it produces 2513 N of push force, rising to 4523 N at the maximum operating pressure of 0.9 MPa, making it a strong actuator for short, direct linear moves.
This model uses a 25 mm diameter piston rod with M20x1.5 male threads and PT3/8 inlet ports. The cylinder body length A is 182 mm, giving a compact extended length of 232 mm. The adjustable air cushion at each end decelerates the piston smoothly over 28 mm, protecting end caps during high-cycle operation.

Where the Airtac SC80 Standard Cylinder SC80X50FA Is Used
Clamping & Pressing
The 2513 N force at 0.5 MPa makes this cylinder ideal for pneumatic toggle clamps and short-stroke pressing fixtures in assembly jigs.
Part Stops & Gates
Used as a robust pneumatic stop on conveyor lines, the 50 mm stroke provides a fast, positive gate action to separate or position products.
Die Ejection
Mounts directly to a machine panel via the front flange to eject small stamped or molded parts with a quick, repeatable 50 mm push.
Is the Airtac SC80 Standard Cylinder SC80X50FA the Right Cylinder?
Choose the SC80 bore when 63 mm bore force (1559 N push at 0.5 MPa) is marginal. If your load requires more than 4523 N at 0.9 MPa, step up to the SC100 bore (3927 N at 0.5 MPa). For this 50 mm stroke, side loading is rarely a concern, but always align the rod axially with the load to prevent premature bearing wear.
To replace an existing cylinder, match five points: 80 mm bore, 50 mm stroke, PT3/8 ports, front flange mount (F-SC80FA), and no magnet. This tie-rod cylinder is shorter than an ISO 15552 profile, so dimensional interchangeability is limited to other AirTAC SC series units.
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 SC80X50FA FAQ
At 0.7 MPa (7 bar) the SC80X50FA generates 3518 N of push force and 3175 N of pull force. The maximum push force at the 0.9 MPa operating limit is 4523 N.
Yes. The FA suffix means this model includes a front rectangular flange (accessory code F-SC80FA) bolted to the rod-end cap. It is designed to mount the cylinder rigidly onto a flat surface perpendicular to the rod axis.
