About the Airtac SC80 Standard Cylinder SC80X665S
The SC80X665S is a double-acting pneumatic cylinder delivering 2513 N of push force at 0.5 MPa and up to 4523 N at 0.9 MPa, making it a robust actuator for medium-to-heavy linear tasks. Its 25 mm diameter rod and 28 mm adjustable air cushion at each end provide smooth deceleration, while the 665 mm stroke suits applications requiring extended reach without stepping up to a larger frame size.
This model includes a built-in magnet (-S suffix), allowing direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors on the tie-rod barrel for reliable end-of-stroke or mid-position detection. The body length A is 182 mm, giving a total extended length of approximately 847 mm, and it operates on 40 µm filtered air with a standard PT1/8 port.

Where the Airtac SC80 Standard Cylinder SC80X665S Is Used
Material Handling Pushers
The 665 mm stroke and 2513 N push force at 0.5 MPa efficiently transfer boxes or pallets between conveyor lines, with the built-in magnet enabling precise position feedback to the PLC.
Automated Clamping Fixtures
Delivers up to 4523 N of clamping force at 0.9 MPa for holding large workpieces during welding or assembly. The adjustable cushion protects the fixture from impact shock.
Bin Tipping and Sorting Gates
Ideal for actuating heavy diverter gates or tipping mechanisms in logistics hubs. The -S magnet allows sensors to confirm open/closed states in dusty environments.
Is the Airtac SC80 Standard Cylinder SC80X665S the Right Cylinder?
Choose the SC80 bore when your application needs between 2513 N and 4523 N of thrust; if force requirements are lower, stepping down to the SC63 bore (1559 N at 0.5 MPa) can reduce air consumption and physical size. For higher demands, the SC100 bore provides 3927 N at 0.5 MPa. At a 665 mm stroke, ensure the rod is not subjected to significant side loading—long, unsupported strokes can cause rod bending and premature bearing wear. Use an external linear guide or a guided cylinder if off-axis forces are present.
For a direct replacement, match five key attributes: 80 mm bore, 665 mm stroke, PT port thread, the built-in magnet for sensor compatibility, and the basic (no bracket) mounting configuration. This tie-rod cylinder is shorter than an ISO 15552 profile and is not dimensionally interchangeable with that standard.

- ✓ 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 SC80X665S FAQ
At the standard 0.7 MPa operating pressure, the push force is 3518 N and the pull force is 3175 N. At the maximum operating pressure of 0.9 MPa, push force reaches 4523 N. The theoretical maximum at 1.0 MPa is 513 kgf.
Yes. The -S suffix indicates a built-in magnetic piston, so AirTAC CMSG, DMSG, or EMSG sensors clip directly onto the cylinder's tie-rod barrel. No external actuator or mounting hardware is needed for position sensing.
