About the Airtac SC80 Standard Cylinder SC80X490S
The SC80X490S is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining an 80 mm bore with a 490 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 the built-in magnet option (-S), allowing CMSG, DMSG, or EMSG reed and solid-state sensors to be mounted directly onto the barrel for contactless position sensing. The adjustable air cushion at each end (28 mm length) decelerates the piston smoothly, and the total extended body length is approximately 672 mm.

Where the Airtac SC80 Standard Cylinder SC80X490S Is Used
Material Handling Gates
Actuates diverter gates on conveyor systems. The 490 mm stroke provides the long travel needed to fully open or close material flow paths, while the built-in magnet confirms gate position.
Automated Press Feeding
Pushes heavy sheet metal blanks into a stamping press. The 2513 N force at 0.5 MPa reliably moves large workpieces, and the adjustable cushion prevents impact damage at the end of the 490 mm stroke.
Pallet Layer Transfer
Shifts completed pallet layers onto a stretch wrapper infeed. The long, controlled stroke with magnetic piston sensing ensures each layer is transferred completely and the cylinder is ready for the next cycle.
Is the Airtac SC80 Standard Cylinder SC80X490S the Right Cylinder?
Select the SC80 bore when your application requires between 2513 N and 4523 N of force. If you need a more compact solution with lower force, the 63 mm bore delivers 1559 N at 0.5 MPa. For higher force requirements, step up to the 100 mm bore, which provides 3927 N at the same pressure.
At a 490 mm stroke, the 25 mm rod is extended significantly. For applications with any side load, use an external guide or a guided cylinder to prevent rod bending and premature bearing wear. As a genuine AirTAC replacement, ensure your new cylinder matches the 80 mm bore, 490 mm stroke, PT port thread, built-in magnet, and basic mounting configuration.
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 SC80X490S FAQ
The theoretical force for an 80 mm bore is 2513 N pushing and 2268 N pulling at 0.5 MPa. At the maximum operating pressure of 0.9 MPa, the push force increases to 4523 N. For precise sizing, always factor in your specific working pressure.
Yes. The -S suffix includes a magnet in the piston, making it compatible with AirTAC CMSG (reed) and DMSG/EMSG (solid-state) sensors that clamp directly onto the cylinder's tie-rod barrel. This provides a clean, non-contact method for end-of-stroke or mid-stroke position detection.
