About the Airtac SC80 Standard Cylinder SC80X290S
The SC80X290S is an 80 mm bore double-acting pneumatic cylinder with a 290 mm stroke, delivering 2513 N of push force at 0.5 MPa and up to 4523 N at the maximum operating pressure of 0.9 MPa. This model includes a built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG reed and solid-state sensors to clamp directly onto the tie-rod barrel for non-contact position sensing.
With a 25 mm diameter piston rod and M20x1.5 rod thread, the cylinder provides robust guidance for medium-duty linear tasks. The body length A is 182 mm, giving a total extended length of approximately 472 mm. An adjustable air cushion (28 mm length) decelerates the piston smoothly at end-of-stroke, reducing impact and noise. This genuine AirTAC SC unit is a compact tie-rod design, shorter than an equivalent ISO 15552 cylinder.

Where the Airtac SC80 Standard Cylinder SC80X290S Is Used
Material Handling Pushers
The 2513 N push force at 0.5 MPa easily moves boxes, totes, and components on conveyor lines, with the 290 mm stroke providing ample reach for diverting or positioning.
Automated Clamping & Assembly
Delivers controlled clamping force for jigs and fixtures. The built-in magnet enables end-of-stroke sensor confirmation for automated assembly sequences.
Press & Forming Assist
With up to 4523 N of force at 0.9 MPa, this cylinder can power light-duty pressing, bending, or forming operations where consistent pneumatic force is required.
Is the Airtac SC80 Standard Cylinder SC80X290S the Right Cylinder?
For applications needing more force, stepping up to the 100 mm bore SC100 series provides 3927 N of push at 0.5 MPa. If space or force requirements are lower, the 63 mm bore SC63 series offers 1559 N at the same pressure. When replacing an existing cylinder, match five points: 80 mm bore, 290 mm stroke, PT1/8 port thread, the built-in magnet (-S), and the basic (no bracket) mounting style.
At a 290 mm stroke, the 25 mm rod is well-supported for axial loads, but any significant side loading requires an external linear guide or a guided cylinder to prevent rod bending and premature bearing wear. The SC80X290S is a double-acting cylinder and will not hold its position if air pressure is lost; for load-holding, a pilot-operated check valve or external rod lock is necessary.
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 SC80X290S FAQ
At 0.5 MPa, 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 reaches 4523 N. These values are based on the 80 mm bore and 25 mm rod diameter.
Yes. The -S suffix in SC80X290S indicates a built-in magnet on the piston. This allows AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors to be clamped onto the tie-rod barrel for reliable, non-contact position detection.
