About the Airtac SC80 Standard Cylinder SC80X900SFB
The SC80X900SFB delivers a robust 2513 N of push force at 0.5 MPa, scaling up to 4523 N at the maximum operating pressure of 0.9 MPa, making it a powerful workhorse for long linear movements. This specific configuration includes a built-in magnet, a rear rectangular flange (FB) for secure end-face mounting, and a standard TPU seal for a wide operating temperature range of -20 to +70 °C.
With an 80 mm bore and a substantial 900 mm stroke, the cylinder's 25 mm diameter piston rod provides excellent rigidity for demanding push/pull tasks. The total extended body length is approximately 1082 mm, and the adjustable pneumatic cushioning, with a 28 mm cushion length, effectively decelerates the piston at each end of the stroke to absorb impact energy and ensure smooth, quiet operation.

Where the Airtac SC80 Standard Cylinder SC80X900SFB Is Used
Pallet Transfer Systems
The 900 mm stroke and 2513 N push force are ideal for shifting heavy pallets between conveyor lanes in automated warehouses, with the rear flange providing a rigid, stationary mounting point.
Long-Stroke Clamping Fixtures
Provides consistent, powerful clamping pressure over a long travel distance in woodworking or metal fabrication jigs, where the integrated magnet enables precise end-of-stroke position sensing.
Material Pusher for Saws
Handles the high-force, repetitive task of pushing heavy raw stock into a cut-off saw, with the adjustable cushioning absorbing the shock of the moving load at the end of the 900 mm stroke.
Is the Airtac SC80 Standard Cylinder SC80X900SFB the Right Cylinder?
Select the SC80 bore when your application requires a push force between 2513 N and 4523 N. If your load is lighter, stepping down to a 63 mm bore (1559 N at 0.5 MPa) can reduce air consumption and physical size. For a 900 mm stroke, careful side-load management is critical; the extended rod is susceptible to bending under lateral forces, so an external linear guide or a guided cylinder is strongly recommended to protect the rod bearing and seal.
To ensure a correct drop-in replacement, match five key specifications: an 80 mm bore, a 900 mm stroke, a PT1/4 port thread, a rear flange (FB) mount, and a built-in magnet for sensor compatibility. This model uses the F-SC80FB mounting flange and is compatible with CMSG/DMSG/EMSG sensors that clamp directly onto the tie-rod barrel.
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 SC80X900SFB FAQ
The theoretical push force on the piston's full bore area is 2513 N at 0.5 MPa, 3518 N at 0.7 MPa, and reaches 4523 N at the maximum operating pressure of 0.9 MPa. The pull force on the rod side is slightly lower due to the 25 mm rod diameter, delivering 2268 N at 0.5 MPa.
No. The AirTAC SC series is a tie-rod cylinder with a shorter body length than a comparable ISO 15552 profile cylinder, so it is not dimensionally interchangeable. It is a direct replacement only for another AirTAC SC80 tie-rod cylinder with identical bore, stroke, PT ports, rear flange mounting, and a built-in magnet.
