About the Airtac SC80 Standard Cylinder SC80X400FA
The AirTAC SC80X400FA is a double-acting single-rod tie-rod cylinder delivering 2513 N push force at 0.5 MPa and up to 4523 N at 0.9 MPa. With an 80 mm bore and 400 mm stroke, it handles mid-range linear actuation tasks where a rigid front flange mount is preferred. The 25 mm diameter piston rod and 28 mm adjustable air cushion provide smooth deceleration at stroke end.
This model includes the FA front rectangular flange (F-SC80FA), bolting directly to the rod-end face for secure panel or bulkhead mounting. The body length A is 182 mm, giving a total extended length of approximately 582 mm. Ports are PT3/8, and the rod thread is M20x1.5. Operating pressure spans 0.15–1.0 MPa with TPU seals rated for -20 to +70 °C.

Where the Airtac SC80 Standard Cylinder SC80X400FA Is Used
Panel Press Tool
The front flange mount and 2513 N push force at 0.5 MPa make this cylinder ideal for a panel press or riveting fixture where the cylinder body is fixed to a vertical plate.
Product Gate Actuator
With a 400 mm stroke and adjustable cushion, it reliably operates a product diverter gate on a conveyor line, handling frequent cycling without hard end-of-stroke impacts.
Material Lift Assist
The 2268 N pull force at 0.5 MPa supports lifting and lowering a moderate load in a material handling station, where the FA flange mounts the cylinder rigidly to the machine frame.
Is the Airtac SC80 Standard Cylinder SC80X400FA the Right Cylinder?
Choose the SC80 when the SC63's 1559 N at 0.5 MPa is insufficient; step up to the SC100 (3927 N at 0.5 MPa) if higher force is needed. For this 400 mm stroke, confirm that side loads are minimal or use an external guide—long unsupported rods are vulnerable to bending and seal wear. The FA flange suits end-face mounting where the cylinder body must not pivot.
To replace an existing cylinder, match five points: 80 mm bore, 400 mm stroke, PT3/8 port thread, FA front flange mounting, and no magnet. This SC is a tie-rod design and is not dimensionally interchangeable with ISO 15552 profile cylinders.
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 SC80X400FA FAQ
At 0.7 MPa operating pressure, the SC80 bore generates 3518 N of push force. The pull force at the same pressure is 3175 N (calculated from the 25 mm rod area).
No. The AirTAC SC series is a tie-rod cylinder with a shorter body length than ISO 15552 profile cylinders. The mounting dimensions and overall length differ, so it is not a direct replacement. Match another AirTAC SC80 with the same stroke, port thread, and FA flange.
