About the Airtac SC80 Standard Cylinder SC80X680SN
The AirTAC SC80X680SN is an 80 mm bore double-acting tie-rod cylinder delivering 2513 N push force at 0.5 MPa and up to 4523 N at 0.9 MPa. Its 680 mm stroke is well within the 1500 mm maximum standard stroke for this bore, and the 25 mm diameter piston rod with M20x1.5 thread provides robust linear guidance.
This model includes a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG reed or solid-state sensors on the barrel, enabling precise end-of-stroke or mid-position detection. The -N suffix specifies NBR (nitrile) seals, suitable for standard operating temperatures from -20 to +70 °C. Ports are PT1/8, and the adjustable pneumatic cushion (28 mm length) decelerates the piston smoothly at stroke ends.

Where the Airtac SC80 Standard Cylinder SC80X680SN Is Used
Material Transfer
Pushes or diverts boxes and totes on a packaging conveyor with 2513 N of force at 0.5 MPa, using the 680 mm stroke to span wide belt sections. Magnetic sensors confirm full extension and retraction.
Press-Fit Assembly
Delivers up to 4523 N at 0.9 MPa for inserting bearings or bushings into housings. The 25 mm rod resists buckling under the 680 mm stroke, and the adjustable cushion protects the assembly tooling.
Woodworking Clamp
Acts as a long-stroke hold-down clamp on a CNC router bed, securing large panels. The built-in magnet allows position sensors to interlock with the spindle start, preventing crashes.
Is the Airtac SC80 Standard Cylinder SC80X680SN the Right Cylinder?
Choose the SC80 for applications needing around 2500 N of force at standard plant pressure. If your load requires less force, stepping down to the SC63 bore reduces push force to 1559 N at 0.5 MPa, saving air consumption. For higher demands, the SC100 bore provides 3927 N at the same pressure. At this 680 mm stroke, ensure the rod is not subjected to significant side loads; if lateral forces are present, use an external guide rail or a guided cylinder to prevent rod bending and premature seal wear. For direct replacement, match the 80 mm bore, 680 mm stroke, PT1/8 port thread, NBR seal material, and the built-in magnet for sensor compatibility.
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 SC80X680SN 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. The theoretical maximum force at 1.0 MPa is 513 kgf.
Yes. The -S suffix in the model code SC80X680SN indicates a built-in magnet on the piston. This allows AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors to be clamped directly onto the barrel's sensor groove for contactless position detection.
