About the Airtac SC80 Standard Cylinder SC80X400S
The SC80X400S is an 80 mm bore, 400 mm stroke double-acting pneumatic cylinder from the AirTAC SC tie-rod series. It generates a substantial 2513 N of push force when supplied with 0.5 MPa air pressure, and up to 4523 N at the maximum operating pressure of 0.9 MPa, making it a robust choice for medium-duty linear actuation.
This model includes a built-in magnet (denoted by the -S suffix), allowing easy mounting of CMSG, DMSG, or EMSG reed and solid-state sensors directly onto the barrel for precise, contactless end-of-stroke detection. The 25 mm diameter piston rod and 28 mm adjustable air cushion at each end ensure smooth deceleration, even under significant inertial loads.

Where the Airtac SC80 Standard Cylinder SC80X400S Is Used
Conveyor Diverting
Provides the 2513 N force needed to reliably push packages off a main conveyor line onto a sorting spur, with the 400 mm stroke covering wide belt sections.
Press-to-Lock Fixture
Clamps large fabricated metal parts for welding or assembly, using the full 400 mm stroke to retract completely clear of the workstation for easy loading and unloading.
Waste Compactor Feed
Drives a ram plate forward to feed bulky waste material into a compactor chamber, leveraging the high 4523 N force at 0.9 MPa for dense material compression.
Is the Airtac SC80 Standard Cylinder SC80X400S the Right Cylinder?
Select the SC80 bore when your application requires a push force between the 1559 N of the SC63 and the 3927 N of the SC100 at 0.5 MPa. For this 400 mm stroke, ensure the load is guided and side forces are minimal; an unsupported 25 mm rod at full extension is vulnerable to bending under lateral loads. For high side-load applications, consider an external guide rail or a guided cylinder.
When replacing an existing cylinder, match these five points exactly: 80 mm bore, 400 mm stroke, PT1/8 port thread, the built-in magnet for sensor compatibility, and the basic (no bracket) mounting configuration. This ensures a direct functional and dimensional swap with another AirTAC SC80X400S unit.
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 SC80X400S FAQ
At the standard 0.5 MPa operating pressure, 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 increases to 4523 N. The theoretical maximum force at 1.0 MPa is 513 kgf.
Yes. The '-S' in the model code SC80X400S confirms a built-in magnetic piston ring. This allows you to directly clamp AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors onto the barrel's tie-rod slots to detect piston position without additional brackets.
