About the Airtac SC80 Standard Cylinder SC80X70S
The AirTAC SC80X70S is an 80 mm bore, 70 mm stroke double-acting tie-rod cylinder with a factory-installed magnet, ready for sensor feedback. At 0.5 MPa it pushes with 2513 N and pulls with 2268 N, placing it in a mid-range force class suitable for pressing, clamping, and lifting tasks. The 25 mm diameter piston rod and adjustable air cushion (28 mm length) help manage end-of-stroke deceleration for smoother cycling.
This model uses a PT1/8 port and an M20x1.5 rod thread. The built-in magnet allows CMSG, DMSG, or EMSG reed and solid-state sensors to mount directly on the barrel for reliable position sensing without external brackets. The standard TPU seals give an operating temperature range of -20 to +70 °C.

Where the Airtac SC80 Standard Cylinder SC80X70S Is Used
Automated Pressing & Staking
The 2513 N push force at 0.5 MPa makes this cylinder ideal for small pneumatic presses, rivet staking, or bearing insertion where consistent force and end-of-stroke sensing are required.
Diverter Gate Actuation
Use the SC80X70S to shift a diverter gate on a conveyor line. The built-in magnet lets you confirm gate position with a CMSG sensor, ensuring packages route correctly.
Pallet Stop & Lift
Deploy this cylinder as a pallet stop or short-stroke lift in material handling. The 2268 N pull force retracts the stop cleanly, and the magnetic piston enables easy sensor integration for automated control.
Is the Airtac SC80 Standard Cylinder SC80X70S the Right Cylinder?
Choose the SC80 when the SC63's 1559 N push at 0.5 MPa is marginal for your load. If you need more force, the SC100 delivers 3927 N at the same pressure. For this 70 mm stroke, the rod is well-supported inside the barrel, but if you later move to strokes above 300 mm, consider an external guide or a guided cylinder to protect the rod bearing from side loads.
To replace an existing cylinder, match five points: 80 mm bore, 70 mm stroke, PT port thread, the built-in magnet (-S suffix), and the basic mounting style. This is a genuine AirTAC tie-rod cylinder, shorter than an ISO 15552 profile, so dimensional interchangeability is limited to other AirTAC SC80 units or equivalent tie-rod designs.
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 SC80X70S FAQ
At 0.5 MPa the push force is 2513 N and pull force is 2268 N. At 0.7 MPa push rises to 3518 N, and at the maximum operating pressure of 0.9 MPa it reaches 4523 N. These values are based on the 80 mm bore and 25 mm rod diameter.
Yes. The -S suffix in SC80X70S means a magnet is built into the piston. You can clamp AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the barrel to detect piston position without any additional brackets.
