About the Airtac SC80 Standard Cylinder SC80X50FB
The SC80X50FB is an 80 mm bore double-acting pneumatic cylinder from the AirTAC SC tie-rod series, configured with a 50 mm standard stroke and a rear rectangular flange (FB mount). At 0.5 MPa it generates a push force of 2513 N, moving a 25 mm diameter piston rod through a compact cycle ideal for clamping and short-transfer tasks.
The cylinder body measures 182 mm (dimension A) and uses 28 mm adjustable air cushions to decelerate the piston quietly. Its PT3/8 ports and M20x1.5 rod thread suit standard pneumatic fittings. The FB flange (part F-SC80FB) bolts directly to a machine face, providing rigid, perpendicular mounting from the cap end.

Where the Airtac SC80 Standard Cylinder SC80X50FB Is Used
Short-Stroke Part Stops
The 50 mm stroke and rear flange mount create a rigid stop or gate on conveyor lines, reliably halting 80 mm bore force class loads in packaging and assembly tracks.
Fixture Clamping
Delivers 2513 N of clamping force at 0.5 MPa to hold workpieces on CNC fixtures or welding jigs, with the FB flange bolted directly to the machine table for stability.
Press-Fit Assembly
Ideal for short press-fit operations where the 80 mm bore provides ample force to insert bearings or bushings, and the adjustable cushion prevents impact damage at end of stroke.
Is the Airtac SC80 Standard Cylinder SC80X50FB the Right Cylinder?
Choose the SC80X50FB when 80 mm bore force (2513 N push at 0.5 MPa) meets the load requirement. If you need higher force, step up to the SC100 series (3927 N at 0.5 MPa); for a lighter assembly, the SC63 delivers 1559 N. The short 50 mm stroke keeps the envelope tight, but ensure the load is guided—side forces on the 25 mm rod can cause premature bearing wear. For direct replacement, match bore, stroke, PT3/8 port thread, FB rear flange mount, and confirm the magnet option is not required.
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 SC80X50FB FAQ
At 0.7 MPa operating pressure, the SC80X50FB produces a push force of 3518 N. The maximum push force at 0.9 MPa is 4523 N. Pull force at 0.5 MPa is 2268 N.
No. The AirTAC SC series is a tie-rod cylinder and is dimensionally shorter than an ISO 15552 profile cylinder, so it is not a drop-in interchange. It replaces another AirTAC SC80 tie-rod cylinder of the same bore, stroke, PT port thread, and FB rear flange mount.
