About the Airtac SC80 Standard Cylinder SC80X675S
The SC80X675S is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining an 80 mm bore with a 675 mm stroke. It generates a push force of 2513 N at 0.5 MPa and up to 4523 N at the maximum operating pressure of 0.9 MPa, driven by a 25 mm diameter piston rod.
This model includes a built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG reed and solid-state sensors to be mounted directly on the barrel for non-contact position sensing. The cylinder body length is 182 mm, resulting in a total extended length of approximately 857 mm, and the adjustable pneumatic cushion (28 mm) decelerates the piston at both ends to reduce impact energy.

Where the Airtac SC80 Standard Cylinder SC80X675S Is Used
Material Handling Pusher
The 675 mm stroke and 2513 N push force at 0.5 MPa make this cylinder ideal for diverting or pushing medium-weight packages off a conveyor line, with the built-in magnet providing end-of-stroke confirmation.
Automated Clamping Station
Delivers consistent clamping force for workpieces in CNC or welding fixtures. The adjustable cushion ensures smooth, low-impact engagement at the end of the long 675 mm travel.
Lift-and-Transfer Mechanism
Used in a vertical lift-and-transfer unit to raise and lower a carriage. The magnet-equipped barrel enables reliable mid-stroke and end-stroke sensor feedback for sequencing.
Is the Airtac SC80 Standard Cylinder SC80X675S the Right Cylinder?
For applications needing more force, stepping up to the 100 mm bore SC100 series provides 3927 N at 0.5 MPa. If space is constrained, the 63 mm bore delivers 1559 N at the same pressure. At a 675 mm stroke, the 25 mm rod is well-supported, but any significant side load requires an external guide or a guided cylinder to prevent rod bearing wear and bending.
When replacing this cylinder, match five key points: 80 mm bore, 675 mm stroke, PT port thread (PT3/8), the basic mounting configuration, and the integrated magnet for sensor compatibility. The SC is a tie-rod design and is not dimensionally interchangeable with ISO 15552 profile cylinders.
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 SC80X675S FAQ
At the standard 0.5 MPa operating pressure, 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.
Yes. The -S suffix in the model code SC80X675S 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 for position detection.
