About the Airtac SC80 Standard Cylinder SC80X143S
The SC80X143S is a double-acting pneumatic cylinder delivering 2513 N of push force at 0.5 MPa and up to 4523 N at the maximum 0.9 MPa operating pressure. With an 80 mm bore, 25 mm piston rod, and a 143 mm stroke, this model includes a built-in magnet that allows CMSG, DMSG, or EMSG reed and solid-state sensors to be clamped directly onto the tie-rod barrel for precise end-of-stroke or mid-stroke position sensing.
This genuine AirTAC SC series cylinder uses a PT3/8 port and an M20x1.5 rod thread, with a 28 mm adjustable air cushion at each end to decelerate the piston quietly. The body length A is 182 mm, giving a total extended length of approximately 325 mm. The standard TPU/NBR seals suit operating temperatures from -20 to +70 °C, and the tie-rod construction keeps the overall length shorter than an equivalent ISO 15552 profile cylinder.

Where the Airtac SC80 Standard Cylinder SC80X143S Is Used
Packaging Line Diverters
The 143 mm stroke and 2513 N push force at 0.5 MPa reliably actuate product diverters and sortation gates on medium-speed packaging conveyors, with the built-in magnet providing sensor confirmation of gate position.
Clamping & Assembly Fixtures
Delivers consistent clamping force up to 4523 N at 0.9 MPa for holding workpieces during welding or assembly. The 25 mm rod resists deflection, and CMSG sensors verify clamp engagement before the cycle starts.
Pallet Stop & Lift Stations
Ideal for raising and lowering pallet stops or lift-and-transfer stations in material handling. The adjustable air cushion absorbs impact at both ends of the 143 mm stroke, reducing wear in high-cycle warehouse operations.
Is the Airtac SC80 Standard Cylinder SC80X143S the Right Cylinder?
Choose the SC80 bore when your application needs roughly 2500 N of force at standard shop air; if you require less force, the SC63 bore provides 1559 N at 0.5 MPa, while stepping up to the SC100 bore delivers 3927 N. For this 143 mm stroke, the rod bearing is well supported, but if you later specify strokes above 300 mm, consider an external guide or a guided cylinder to protect the 25 mm rod from side-load bending.
To replace an existing cylinder, match five points: 80 mm bore, 143 mm stroke, PT3/8 port thread, the built-in magnet (the -S suffix), and the basic (no-bracket) mounting. The SC80X143S is not dimensionally interchangeable with ISO 15552 cylinders; it is a direct replacement for another AirTAC SC80 tie-rod cylinder with the same sensor-ready magnet option.
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 SC80X143S FAQ
At 0.5 MPa the cylinder pushes with 2513 N and pulls with 2268 N. At 0.7 MPa push force rises to 3518 N, and at the maximum operating pressure of 0.9 MPa it reaches 4523 N. The theoretical maximum at 1.0 MPa is 513 kgf. These values assume clean, filtered air at 40 µm and standard TPU/NBR seals.
Yes. The -S suffix indicates a built-in magnet inside the piston, so AirTAC CMSG (reed) and DMSG/EMSG (solid-state) sensors can be clamped directly onto the tie-rod barrel without any additional brackets. This lets you sense end-of-stroke or intermediate positions for sequence control.
