About the Airtac SC80 Standard Cylinder SC80X300SFA
The SC80X300SFA is a double-acting pneumatic cylinder delivering 2513 N of push force at 0.5 MPa and up to 4523 N at 0.9 MPa. Its 80 mm bore and 300 mm stroke suit medium-duty linear tasks requiring a robust 25 mm diameter piston rod and an adjustable air cushion for smooth end-of-stroke deceleration.
This configuration includes a built-in magnet for direct mounting of CMSG/DMSG/EMSG sensors and an FA front rectangular flange for secure panel attachment. The body length A is 182 mm, giving a total extended length of approximately 482 mm. As a genuine AirTAC tie-rod cylinder, it offers a compact, serviceable design that is shorter than an equivalent ISO 15552 cylinder.

Where the Airtac SC80 Standard Cylinder SC80X300SFA Is Used
Package Diverter
Actuates a gate or pusher on a conveyor line, using the 300 mm stroke to divert cartons. The front flange mount provides rigid alignment, and the magnetic piston enables end-of-stroke position feedback.
Clamping Fixture
Applies controlled clamping force in a woodworking or welding jig. The 4523 N maximum thrust at 0.9 MPa securely holds workpieces, while the adjustable cushion prevents impact vibration.
Press Feed Mechanism
Pushes material stock into a stamping press with a consistent 300 mm advance. The built-in magnet allows sensors to confirm full extension and retraction, critical for automated die protection.
Is the Airtac SC80 Standard Cylinder SC80X300SFA the Right Cylinder?
Choose the SC80 bore when your application needs between 2513 N and 4523 N of force. If you require less force, stepping down to the SC63 bore provides 1559 N at 0.5 MPa; for higher demands, the SC100 bore delivers 3927 N at the same pressure. This 300 mm stroke model uses a 25 mm rod—for strokes of this length, ensure the load is guided and side forces are minimized to prevent rod bearing wear or bending.
For a direct replacement, match these five points: 80 mm bore, 300 mm stroke, PT port thread, FA front flange mounting (F-SC80FA), and the built-in magnet (-S) for sensor compatibility. This ensures identical form, fit, and function with your existing setup.
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 SC80X300SFA FAQ
At 0.5 MPa, the cylinder provides 2513 N pushing and 2268 N pulling. At the maximum operating pressure of 0.9 MPa, the push force increases to 4523 N. These values are based on the 80 mm bore and 25 mm rod diameter.
Ensure your current cylinder matches these specifications: 80 mm bore, 300 mm stroke, PT port thread, FA front flange mounting (accessory F-SC80FA), and a built-in magnet for sensors. The SC series is a tie-rod design and is not dimensionally interchangeable with ISO 15552 profile cylinders.
