About the Airtac SC80 Standard Cylinder SC80X670FB
The SC80X670FB is an 80 mm bore, 670 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, scaling up to 4523 N at the maximum operating pressure of 0.9 MPa, making it a robust choice for medium-to-heavy linear actuation tasks.
This model is configured with an FB rear rectangular flange (mounting accessory F-SC80FB) for secure end-face mounting. It features a 25 mm diameter piston rod, PT3/8 port threads, and a 28 mm adjustable air cushion to decelerate the piston smoothly at stroke end. The total extended body length is approximately 852 mm.

Where the Airtac SC80 Standard Cylinder SC80X670FB Is Used
Pallet Stop & Transfer
The 670 mm stroke and high force output are ideal for lifting or transferring heavy pallets between conveyor sections, where the rear flange mount provides a rigid, fixed anchoring point.
Press & Clamping Fixtures
Delivers up to 4523 N of clamping force at 0.9 MPa. The adjustable cushioning protects tooling from impact damage during high-speed clamp-and-release cycles in assembly jigs.
Grain Chute Diverter
The long stroke and robust tie-rod construction suit agricultural handling equipment. The FB mount allows direct bolting to a bulkhead to actuate a heavy diverter gate with reliable pneumatic power.
Is the Airtac SC80 Standard Cylinder SC80X670FB the Right Cylinder?
Choose the SC80 when your application requires a force class between the smaller SC63 (1559 N push at 0.5 MPa) and the larger SC100 (3927 N push at 0.5 MPa). For this 670 mm stroke, carefully evaluate side-loading conditions; an unsupported 25 mm rod extending over half a meter is susceptible to bending under radial forces. In such cases, integrate an external linear guide or switch to a guided cylinder to protect the rod bearings and ensure long service life.
To replace an existing unit, match five key points: the 80 mm bore, 670 mm stroke, PT3/8 port thread, the FB rear flange mounting style, and the absence of a built-in magnet on this model. The SC series is a tie-rod design and is dimensionally shorter than a standard ISO 15552 cylinder, so it is not a drop-in replacement for that profile.
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 SC80X670FB FAQ
At the standard 0.5 MPa operating pressure, the cylinder provides 2513 N of push force and 2268 N of pull force. At the maximum operating pressure of 0.9 MPa, the push force increases to 4523 N.
No. The SC80X670FB is a standard double-acting cylinder and will not hold its position if air pressure is lost or the directional valve is centered. The piston will drift or drop under load. To safely hold a position or a suspended load, you must add an external mechanical rod lock or a pilot-operated check valve.
