About the Airtac SC80 Standard Cylinder SC80X1490S
The SC80X1490S is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, delivering a substantial 2513 N of push force at 0.5 MPa and up to 4523 N at the maximum operating pressure of 0.9 MPa. With an 80 mm bore and a long 1490 mm stroke, this model is built for applications requiring extended linear travel, such as material transfer or large gate actuation. The 25 mm diameter piston rod and 28 mm adjustable air cushion at each end ensure robust, controlled motion.
This cylinder features a built-in magnet, designated by the -S suffix, allowing for direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors on the barrel for precise position feedback. The total extended body length is approximately 1672 mm (body length A of 182 mm plus the stroke). As a genuine AirTAC component, it is engineered for reliable performance in demanding industrial environments.

Where the Airtac SC80 Standard Cylinder SC80X1490S Is Used
Long-Stroke Material Transfer
Pushes or pulls product carriers over a 1490 mm distance on packaging or assembly lines, with sensor feedback confirming end-of-stroke positions.
Automated Gate & Damper Actuation
Operates large sliding gates, dampers, or diverter chutes in bulk material handling, using the built-in magnet for open/close verification.
Tire & Rubber Press Curing
Provides the long, controlled stroke needed to open and close heavy curing press molds, with sensor confirmation of mold closure.
Is the Airtac SC80 Standard Cylinder SC80X1490S the Right Cylinder?
When selecting a cylinder for a 1490 mm stroke, the SC80X1490S operates near the maximum standard stroke limit of 1500 mm for the 80 mm bore. If your application requires a force closer to 1767 N at 0.5 MPa, consider stepping down to a 63 mm bore, but verify that the 63 mm bore's maximum standard stroke of 1500 mm is sufficient. For higher force requirements, the 100 mm bore provides 3927 N at 0.5 MPa.
For strokes of this length, the piston rod is subject to significant bending stress if side loads are present. It is critical to ensure the load is guided externally and that the force is applied purely axially to the rod. If side loading is unavoidable, an external guide rail system or a guided cylinder variant is required to prevent rod bearing damage and seal failure. For replacement, match the 80 mm bore, 1490 mm stroke, PT port thread, and the -S magnet option to ensure sensor compatibility.
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 SC80X1490S FAQ
At the standard operating pressure of 0.7 MPa, the push force is 3518 N. At the maximum operating pressure of 0.9 MPa, it reaches 4523 N. The theoretical force at 1.0 MPa is 513 kgf, but this exceeds the recommended operating range.
No. The AirTAC SC series is a tie-rod cylinder with a shorter body length than an ISO 15552 profile cylinder. It is not dimensionally interchangeable. For a direct replacement, match the bore, stroke, PT port, and the -S magnet option from another AirTAC SC tie-rod cylinder.
