About the Airtac SC80 Standard Cylinder SC80X90S
The SC80X90S is an 80 mm bore, 90 mm stroke double-acting tie-rod cylinder with a built-in magnet, ready for CMSG, DMSG, or EMSG reed and solid-state sensors to clamp directly onto the barrel profile. At 0.5 MPa it generates 2513 N pushing force and 2268 N pulling force, placing it firmly in the mid-range power class for general automation tasks.
With a 25 mm diameter piston rod and M20x1.5 rod thread, this model handles moderate side loads better than smaller bores. The 28 mm adjustable air cushion at each end decelerates the piston smoothly, protecting end caps. Its compact body length A of 182 mm plus the 90 mm stroke gives a total extended length of approximately 272 mm, fitting into tight machine frames where ISO 15552 cylinders are too long.

Where the Airtac SC80 Standard Cylinder SC80X90S Is Used
Package Sorting Gate
The 90 mm stroke and 2513 N push force divert cartons on medium-speed conveyors. The built-in magnet enables end-of-stroke sensing to confirm gate position without external flag sensors.
Clamping & Fixturing
Applies consistent clamping force for CNC woodworking or light metal drilling jigs. The adjustable cushion reduces vibration at clamp contact, protecting the workpiece surface.
Press-Fit Assembly
Delivers a controlled 2513 N insertion force for bearing or bushing press-fit stations. Sensor feedback from the -S magnet confirms full insertion depth on every cycle.
Is the Airtac SC80 Standard Cylinder SC80X90S the Right Cylinder?
Choose the SC80 when the SC63’s 1559 N push force at 0.5 MPa is marginal; stepping up to 80 mm bore nearly doubles the available force without increasing operating pressure. If your application requires even more force, the SC100 delivers 3927 N at the same pressure. For this 90 mm stroke, the standard 25 mm rod is well-supported, but for strokes exceeding 300 mm, consider an external guide or a guided cylinder to protect the rod bearing from bending moments.
To replace an existing unit, match five points: 80 mm bore, 90 mm stroke, PT port thread, the built-in magnet (-S suffix), and the basic mount (no accessory bracket). This ensures identical sensor compatibility and mechanical fit without re-engineering the machine layout.
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 SC80X90S FAQ
At 0.5 MPa air pressure it produces 2513 N pushing and 2268 N pulling. At the maximum operating pressure of 0.9 MPa, the pushing force increases to 4523 N. The theoretical maximum at 1.0 MPa is 513 kgf.
Yes. The -S suffix indicates a built-in magnet inside the piston. AirTAC CMSG (reed) and DMSG/EMSG (solid-state) sensors clamp directly onto the barrel tie-rod slots to detect piston position without additional brackets.
