About the Airtac SC80 Standard Cylinder SC80X80SFB
The SC80X80SFB is a double-acting tie-rod cylinder delivering a robust 2513 N push force at 0.5 MPa (4523 N at 0.9 MPa), making it a strong mid-range actuator for industrial tasks. With an 80 mm stroke and a 25 mm diameter piston rod, this model includes a built-in magnet for direct mounting of CMSG/DMSG/EMSG sensors, enabling reliable end-of-stroke detection without external brackets.
This unit is configured with an FB rear rectangular flange (accessory F-SC80FB) for secure end-face mounting to a machine panel or bulkhead. The PT1/4 port thread and TPU seals suit standard compressed air systems operating from -20 to +70 °C, while the 28 mm adjustable air cushion at each end protects the cylinder from impact damage.

Where the Airtac SC80 Standard Cylinder SC80X80SFB Is Used
Packaging Pusher
The 80 mm stroke and 2513 N push force efficiently divert cartons or products off a conveyor line. The rear flange mount allows rigid attachment to the machine frame, while the magnetic piston lets sensors confirm each push cycle.
Clamping Fixture
Apply 4523 N of clamping force at 0.9 MPa to hold workpieces during machining or assembly. The adjustable cushion decelerates the rod smoothly, preventing vibration that could shift the part.
Press Tool Actuator
Use the SC80 for short-stroke pressing, stamping, or riveting operations. The 25 mm rod diameter provides good column strength for straight-line push forces in compact tooling setups.
Is the Airtac SC80 Standard Cylinder SC80X80SFB the Right Cylinder?
Choose the SC80 bore when your application needs between 2513 N and 4523 N of push force; if loads are lighter, stepping down to the SC63 bore (1559 N at 0.5 MPa) can reduce air consumption and physical size. For heavier demands, the SC100 bore offers 3927 N at 0.5 MPa. The 80 mm stroke is short and stiff, but always ensure the rod is aligned axially with the load to prevent side-load wear on the rod bearing. For a direct replacement, match bore, stroke, PT port thread, the FB rear flange mount, and the -S magnet option exactly with another AirTAC SC series 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 SC80X80SFB 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 at 1.0 MPa is 513 kgf.
Yes. The -S suffix in the model code means this cylinder has a built-in magnet on the piston. You can clamp AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the tie-rod barrel to detect end-of-stroke or intermediate positions.
