About the Airtac SC80 Standard Cylinder SC80X280S
The AirTAC SC80X280S is a double-acting pneumatic cylinder delivering 2513 N of push force at 0.5 MPa (4523 N at 0.9 MPa), making it a strong workhorse for medium-to-heavy linear automation. With an 80 mm bore, 25 mm piston rod, and PT3/8 ports, it handles a 280 mm stroke within its standard range, cushioned by 28 mm of adjustable pneumatic deceleration at each end.
This model includes the factory-fitted -S magnet, so CMSG/DMSG/EMSG reed or solid-state sensors clamp directly onto the tie-rod barrel for non-contact position sensing. The body length A is 182 mm, giving an approximate extended length of 462 mm. Operating pressure spans 0.15–1.0 MPa with TPU seals rated for -20 to +70 °C.

Where the Airtac SC80 Standard Cylinder SC80X280S Is Used
Conveyor Divert & Stop
The 280 mm stroke and 2513 N push force at 0.5 MPa reliably actuates heavy package diverters, lane stops, and pallet kickers on distribution conveyors.
Clamping & Assembly Press
Delivers up to 4523 N at 0.9 MPa for pneumatic clamping fixtures, light riveting, or pressing bearings into housings on an assembly line.
Sensor-Monitored Gate Actuator
The built-in magnet (-S) allows CMSG/DMSG sensors to confirm open/closed position on safety gates or material chutes, integrating directly with PLC logic.
Is the Airtac SC80 Standard Cylinder SC80X280S the Right Cylinder?
Choose the SC80 when your application needs roughly 2500 N of force at standard shop air; if your load is lighter, stepping down to the SC63 bore saves space and air (1559 N at 0.5 MPa). For strokes of 280 mm and above, watch for side loading — an unsupported 25 mm rod can bend under off-axis force. Add an external linear guide or switch to a guided cylinder if the load is not perfectly axial.
For a direct replacement, match five points: 80 mm bore, 280 mm stroke, PT3/8 port thread, the built-in magnet (-S suffix), and the basic (no bracket) mounting style. This is a tie-rod cylinder, not an ISO 15552 profile, so dimensional interchangeability is limited to another AirTAC SC80 or an equivalent tie-rod design.
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 SC80X280S FAQ
At 0.5 MPa, push force is 2513 N and pull force is 2268 N. At the maximum operating pressure of 0.9 MPa, push force reaches 4523 N. The theoretical maximum at 1.0 MPa is 513 kgf.
Yes. The -S suffix means a magnet is built into the piston, so AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors clamp directly onto the tie-rod barrel to detect piston position without any modification.
