About the Airtac SC80 Standard Cylinder SC80X80FA
The SC80X80FA is an 80 mm bore, 80 mm stroke double-acting pneumatic cylinder from the AirTAC SC tie-rod series. It generates a substantial 2513 N of push force when operated at 0.5 MPa, making it suitable for medium-duty clamping and pressing tasks. The front rectangular flange (FA) mount allows the cylinder to be rigidly bolted to a machine panel from the rod end, ensuring precise alignment.
This model uses a 25 mm diameter piston rod with an M20x1.5 male thread and PT3/8 ports. The adjustable air cushion at each end is 28 mm long, effectively decelerating the piston to reduce end-of-stroke impact. Its compact body length of 182 mm plus the 80 mm stroke gives a total extended length of 262 mm.

Where the Airtac SC80 Standard Cylinder SC80X80FA Is Used
Part Stops and Gates
The 80 mm bore provides ample force to reliably raise and lower part stops on conveyor lines, controlling the flow of medium-weight packages or pallets without stalling.
Clamping Fixtures
With 2513 N of force at 0.5 MPa, this cylinder is ideal for pneumatic clamping in machining centers, welding jigs, or assembly fixtures where rigid panel mounting via the FA flange is required.
Press-Fit Assembly
The short 80 mm stroke and high force output suit press-fit operations for bearings, bushings, or pins, providing a controlled, repeatable insertion force in a compact footprint.
Is the Airtac SC80 Standard Cylinder SC80X80FA the Right Cylinder?
Select the SC80 bore when your application requires between 2513 N and 4523 N of force at standard plant pressures. If your load is closer to 1500 N, stepping down to a 63 mm bore (1559 N at 0.5 MPa) can reduce air consumption and physical size. For loads exceeding 4500 N, consider moving up to the 100 mm bore (3927 N at 0.5 MPa).
For a direct replacement, match five key points: 80 mm bore, 80 mm stroke, PT3/8 port thread, FA front flange mounting (part code F-SC80FA), and the absence of a magnet. This is a tie-rod cylinder, not an ISO 15552 profile, so dimensional interchangeability is limited to other AirTAC SC series cylinders of the same configuration.
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 SC80X80FA FAQ
At 0.7 MPa operating pressure, the theoretical push force on the extend stroke is 3518 N. The pull force on the retract stroke is 2268 N, accounting for the area reduction from the 25 mm piston rod.
No. The AirTAC SC series is a tie-rod cylinder with a shorter overall body length than an ISO 15552 profile cylinder. The mounting dimensions, tie-rod spacing, and accessory interfaces are not interchangeable. It is a direct fit only for another AirTAC SC80 cylinder with the same stroke and FA front flange mount.
