About the Airtac SC80 Standard Cylinder SC80X650FB
The AirTAC SC80X650FB is a double-acting tie-rod cylinder delivering 2513 N of push force at 0.5 MPa and up to 4523 N at the maximum operating pressure of 0.9 MPa. With an 80 mm bore and a 650 mm stroke, this model is equipped with a rear rectangular flange (FB mount) for secure end-face attachment, making it ideal for linear transfer and pressing applications where the cylinder body must be rigidly fixed from the cap end.
This genuine AirTAC SC series cylinder features a 25 mm diameter piston rod with M20x1.5 male threads and a PT3/8 port. The total extended body length is approximately 832 mm (body length A of 182 mm plus the 650 mm stroke). An adjustable air cushion of 28 mm at each end decelerates the piston smoothly, reducing end-of-stroke impact and noise in high-cycle automation.

Where the Airtac SC80 Standard Cylinder SC80X650FB Is Used
Pallet Stop & Transfer
The 2513 N push force at 0.5 MPa and rear flange mount rigidly stop and transfer heavy pallets on conveyor lines, with the adjustable cushion absorbing impact energy during high-speed indexing.
Panel Press & Clamping
Delivers up to 4523 N of clamping force at 0.9 MPa for woodworking or composite panel presses. The FB flange bolts directly to a machine frame, keeping the cylinder body stable under full thrust.
Diverter Gate Actuation
Operates heavy diverter gates in material handling systems. The 650 mm stroke provides the long travel needed to swing chutes or doors, while the tie-rod construction handles repetitive shock loads.
Is the Airtac SC80 Standard Cylinder SC80X650FB the Right Cylinder?
For applications requiring slightly less force, the 63 mm bore SC63 series provides 1559 N of push force at 0.5 MPa, while stepping up to the 100 mm bore SC100 series offers 3927 N at the same pressure. This 650 mm stroke is a long, unsupported extension; side loads or off-centre mounting can bend the 25 mm rod. Always guide the load externally with a linear rail or rod guide, or consider a guided cylinder assembly to protect the rod bearing and piston seals.
To ensure a direct drop-in replacement, match five key specifications: an 80 mm bore, a 650 mm stroke, a PT3/8 port thread, the FB rear flange mounting accessory (part code F-SC80FB), and the standard non-magnetic piston. This model uses the default TPU seals and PT threads, so verify these match your existing installation.
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 SC80X650FB FAQ
At 0.5 MPa, the push force is 2513 N and the pull force is 2268 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 4523 N. The theoretical maximum force at 1.0 MPa is 513 kgf (5024 N).
No. The SC80X650FB is a double-acting pneumatic cylinder and does not lock or hold position when air pressure is exhausted or the directional valve is centred. The piston will drift or drop under load. For load holding, you must add an external rod brake, a pilot-operated check valve, or a mechanical lock.
