About the Airtac SC80 Standard Cylinder SC80X660S
The SC80X660S is a double-acting pneumatic cylinder delivering 2513 N of push force at 0.5 MPa, scaling to 4523 N at the maximum operating pressure of 0.9 MPa. With an 80 mm bore and a substantial 660 mm stroke, it uses a 25 mm diameter piston rod and PT3/8 ports, providing a robust platform for mid-range industrial linear motion tasks.
This model includes the -S suffix, meaning a built-in magnet is fitted as standard. This allows for direct, non-contact position sensing by clamping CMSG, DMSG, or EMSG reed or solid-state sensors onto the tie-rod barrel, simplifying integration into automated sequences without external brackets. The adjustable air cushion at each end decelerates the piston smoothly over a 28 mm distance, protecting the end caps during high-cycle operation.

Where the Airtac SC80 Standard Cylinder SC80X660S Is Used
Conveyor Diverter Gates
Actuates sorting gates on packaging lines, using the 660 mm stroke to sweep products across wide conveyor sections. The built-in magnet provides end-of-stroke confirmation to the PLC.
Automated Clamping Fixtures
Powers heavy-duty welding or assembly jigs, applying up to 4523 N of clamping force at 0.9 MPa. Sensors on the barrel verify the clamp is fully engaged before the cycle starts.
Palletizer Layer Pushing
Pushes completed layers of boxes onto a pallet with consistent force. The long 660 mm stroke covers the full depth of a standard pallet, and the magnetic piston enables mid-stroke sensing for multi-position stops.
Is the Airtac SC80 Standard Cylinder SC80X660S the Right Cylinder?
Select the SC80 bore when your application requires a force between the 1559 N of the SC63 and the 3927 N of the SC100 at 0.5 MPa. For this 660 mm stroke, the tie-rod design provides inherent rigidity, but any significant side loading must be managed with an external linear guide or rod support to prevent bending of the 25 mm rod and premature bearing wear. This cylinder is a direct form-and-function replacement for another AirTAC SC80X660S unit or a compatible tie-rod cylinder matching the 80 mm bore, 660 mm stroke, PT3/8 ports, and a magnetic piston.

- ✓ 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 SC80X660S FAQ
At the standard operating pressure of 0.7 MPa, the push force is 3518 N and the pull force is 3175 N. The maximum push force at 0.9 MPa is 4523 N. These values are based on the 80 mm bore and 25 mm rod diameter.
Yes. The -S suffix in the model code confirms a built-in magnet is integrated into the piston. You can clamp compatible AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the cylinder's tie-rod barrel to detect piston position without any additional mounting hardware.
