About the Airtac SC80 Standard Cylinder SC80X350S
The AirTAC SC80X350S is a double-acting pneumatic cylinder delivering 2513 N of push force at 0.5 MPa (up to 4523 N at 0.9 MPa). Its 350 mm stroke is well within the 1500 mm maximum standard range for the 80 mm bore, making this a balanced choice for medium-reach linear tasks.
The built-in magnet (suffix -S) allows direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors along the tie-rod barrel for reliable end-of-stroke or mid-position sensing. The 25 mm diameter piston rod and 28 mm adjustable air cushion at each end provide smooth deceleration, while the PT1/8 port threads ensure straightforward pneumatic connections.

Where the Airtac SC80 Standard Cylinder SC80X350S Is Used
Conveyor Diverter Gates
The 350 mm stroke and 2513 N push force at 0.5 MPa reliably actuate diverter gates in medium-duty parcel and package handling lines, with the magnet enabling gate position confirmation.
Automated Welding Fixtures
Clamp and release heavy workpieces in robotic welding cells. The built-in magnet provides clamp-status feedback to the PLC, ensuring cycle safety with the 80 mm bore's powerful hold.
Grain Silo Slide Gates
Operate slide gates on silos or hoppers with the 4523 N maximum thrust at 0.9 MPa. The sensor-ready design confirms full-open or full-closed gate positions in dusty agricultural environments.
Is the Airtac SC80 Standard Cylinder SC80X350S the Right Cylinder?
Choose the SC80 when the 40 mm bore's 628 N (at 0.5 MPa) is insufficient, but the 100 mm bore's 3927 N is more force than your application requires. This model includes the -S magnet, so ensure your control system uses compatible AirTAC sensors. For strokes of 300 mm or longer, like this 350 mm unit, avoid placing side loads directly on the unsupported 25 mm rod; use an external linear guide or rod support to prevent bending and premature bearing wear.
When replacing an existing cylinder, match five points: 80 mm bore, 350 mm stroke, PT port thread, the built-in magnet (-S), and the basic (no bracket) mounting configuration.
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 SC80X350S FAQ
At the standard operating pressure of 0.5 MPa, 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.
Yes. The -S suffix in the model code SC80X350S indicates a built-in magnet inside the piston. This allows you to clamp compatible AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the cylinder's tie-rod barrel to detect piston position without additional brackets.
