About the Airtac SC80 Standard Cylinder SC80X640S
The AirTAC SC80X640S is a double-acting single-rod pneumatic cylinder delivering 2513 N of push force at 0.5 MPa and up to 4523 N at 0.9 MPa. With an 80 mm bore and a 640 mm stroke, it uses a 25 mm diameter piston rod and PT3/8 ports, making it a robust mid-range actuator for general industrial automation.
This model includes the factory-installed -S magnet, allowing CMSG, DMSG, or EMSG reed and solid-state sensors to be clamped directly onto the tie-rod barrel for reliable end-of-stroke detection. The adjustable air cushion at each end (28 mm length) decelerates the piston smoothly, while the TPU seals ensure reliable operation from -20 to +70 C.

Where the Airtac SC80 Standard Cylinder SC80X640S Is Used
Material Handling & Sorting
The 640 mm stroke and 2513 N push force at 0.5 MPa efficiently operate gates, pushers, and diverters on medium-duty conveyor lines, with the built-in magnet providing sensor feedback for automated sorting logic.
Clamping & Assembly Fixtures
Ideal for clamping workpieces in welding or assembly jigs, where the adjustable cushion prevents impact damage and the -S magnet confirms jaw position before the next cycle starts.
Packaging & Palletizing
Drives the vertical or horizontal motion of packaging arms and palletizers. The 4523 N max force at 0.9 MPa handles heavy carton compression, while sensors ensure full stroke completion.
Is the Airtac SC80 Standard Cylinder SC80X640S the Right Cylinder?
Choose the SC80 bore when your application needs between 2513 N and 4523 N of force. If your load requires less force, stepping down to the SC63 bore provides 1559 N at 0.5 MPa in a lighter package. For higher demands, the SC100 bore offers 3927 N at 0.5 MPa.
For this 640 mm stroke, ensure the load is guided externally to prevent side-load bending on the 25 mm rod. When replacing an existing cylinder, match five points: 80 mm bore, 640 mm stroke, PT3/8 port thread, the built-in magnet (-S), and the basic mounting style. This tie-rod cylinder is shorter than an ISO 15552 profile and is not a drop-in replacement for that standard.
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 SC80X640S FAQ
At 0.5 MPa, the push force is 2513 N and the pull force is 2268 N. At the standard 0.7 MPa, push force rises to 3518 N. The maximum operating 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 SC80X640S indicates a built-in magnetic piston. You can directly clamp AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors onto the tie-rod barrel to detect piston position without any additional brackets or modifications.
