About the Airtac SC80 Standard Cylinder SC80X400SN
The SC80X400SN delivers 2513 N of push force at 0.5 MPa and climbs to 4523 N at 0.9 MPa, making it a strong mid-range actuator for general industrial automation. Its 400 mm stroke sits well within the 1500 mm maximum standard stroke for the 80 mm bore, and the 25 mm diameter piston rod provides solid column strength for linear push-pull tasks.
This model includes a built-in magnet (-S suffix) so CMSG, DMSG, or EMSG solid-state sensors clamp directly onto the tie-rod barrel for non-contact position sensing. The N suffix specifies NBR (nitrile) seals, a cost-effective choice for standard temperature environments, while the PT1/4 ports keep the pneumatic connections simple and widely compatible.

Where the Airtac SC80 Standard Cylinder SC80X400SN Is Used
Conveyor Divert Gates
Directs packages or parts on medium-duty conveyors. The 400 mm stroke spans wide belt sections, and the built-in magnet confirms gate open/closed status.
Press-Fit Assembly
Delivers up to 4523 N at 0.9 MPa for pressing bearings, bushings, or pins into housings. NBR seals handle oily shop air common in manufacturing cells.
Pallet Layer Forming
Positions stacker heads or layer paddles with a 400 mm reach. Sensor feedback from the barrel-mounted CMSG switch ensures consistent layer height.
Is the Airtac SC80 Standard Cylinder SC80X400SN the Right Cylinder?
Choose the SC80 when the 50 mm bore's 982 N at 0.5 MPa is too light; if you need more than 2513 N at 0.5 MPa, step up to the SC100 which delivers 3927 N. For this 400 mm stroke, always check side-load conditions—an unsupported 25 mm rod extending 400 mm can bend under offset loads. Add an external linear guide or switch to a guided cylinder if the load is not perfectly axial.
To replace an existing cylinder, match five points: 80 mm bore, 400 mm stroke, PT1/4 port thread, the built-in magnet for sensor mounting, and the basic (no-bracket) mounting style. The SC is a tie-rod cylinder and is shorter than ISO 15552 profiles, so it is not a direct ISO 15552 replacement.
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 SC80X400SN FAQ
At 0.7 MPa operating pressure, the 80 mm bore generates 3518 N of push force. The pull force at the same pressure is 2268 N, accounting for the 25 mm rod area.
Yes. The -S suffix means a magnet is built into the piston, so AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors clamp onto the tie-rod barrel without any modification.
