About the Airtac SC80 Standard Cylinder SC80X680S
The AirTAC SC80X680S is a double-acting single-rod pneumatic cylinder with an 80 mm bore and a 680 mm stroke, delivering 2513 N of push force at 0.5 MPa. This model includes a built-in magnet (suffix -S), allowing direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors on the barrel for precise, non-contact position feedback.
The 25 mm diameter rod provides robust thrust transfer, and the 28 mm air cushion at each end decelerates the piston smoothly, reducing end-of-stroke impact. With a body length A of 182 mm, the total extended length is approximately 862 mm. The standard PT1/8 port and M20x1.5 rod thread make it a straightforward fit for industrial automation requiring a genuine AirTAC tie-rod cylinder.

Where the Airtac SC80 Standard Cylinder SC80X680S Is Used
Conveyor Diverter Gate
The 680 mm stroke and 2513 N push force efficiently actuate long-throw diverter gates on packaging lines, with the magnetic piston enabling end-of-travel confirmation via barrel-mounted sensors.
Automated Panel Press
Ideal for a woodworking or metal-forming press requiring a consistent 0.5 MPa clamping force over a deep 680 mm draw, with the adjustable cushion protecting tooling from impact damage.
Pallet Stacker Pusher
Provides the long reach needed to push heavy pallets or totes from a stacker onto an accumulation conveyor, where the built-in magnet sensor confirms full extension and retraction.
Is the Airtac SC80 Standard Cylinder SC80X680S the Right Cylinder?
Select the SC80X680S when your application needs the 2513 N push force of an 80 mm bore. If your load requires less force, stepping down to a 63 mm bore provides 1559 N at 0.5 MPa. For higher force demands, the 100 mm bore offers 3927 N. Always match the bore, 680 mm stroke, PT port thread, and the -S magnet option when replacing a legacy cylinder.
For this 680 mm stroke, be mindful of side loading. An unsupported rod of this length is susceptible to bending under lateral forces. To ensure long seal life and prevent rod bearing damage, use an external linear guide or a guided cylinder assembly to absorb any off-axis loads.
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 SC80X680S FAQ
At 0.7 MPa operating pressure, the SC80X680S generates a theoretical push force of 3518 N. The maximum force at 0.9 MPa is 4523 N. For dynamic applications, always factor in a load ratio appropriate for the speed.
Yes. The -S suffix in SC80X680S designates a built-in magnetic piston. This allows you to clamp compatible AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the tie-rod barrel to detect piston position without additional brackets.
