About the Airtac SC80 Standard Cylinder SC80X900S
The SC80X900S is an 80 mm bore, 900 mm stroke double-acting pneumatic cylinder from the AirTAC SC tie-rod series. It generates a substantial push force of 2513 N at 0.5 MPa and can reach 4523 N at the maximum operating pressure of 0.9 MPa, making it well-suited for demanding linear motion tasks. The built-in magnet allows direct mounting of CMSG, DMSG, or EMSG sensors on the barrel for reliable, non-contact position sensing.
With a 25 mm diameter piston rod and an M20x1.5 rod thread, this cylinder provides robust mechanical connection for tooling. The PT3/8 port supplies ample air flow for speeds up to 800 mm/s, while the 28 mm adjustable air cushion at each end decelerates the piston smoothly to reduce end-of-stroke impact. The total extended body length is approximately 1082 mm (182 mm body length A + 900 mm stroke).

Where the Airtac SC80 Standard Cylinder SC80X900S Is Used
Pallet Transfer Systems
Pushes heavy pallets across 900 mm roller conveyors in automated warehouses, with sensor confirmation of full extension and retraction.
Automated Gluing Stations
Advances a glue head assembly along a 900 mm track in a packaging line, using the magnet for precise mid-stroke speed-change signals.
Long-Stroke Part Rejection
Operates a sweep arm to push defective products off a wide conveyor belt, with the adjustable cushion ensuring a quiet, low-impact stop.
Is the Airtac SC80 Standard Cylinder SC80X900S the Right Cylinder?
Select the SC80X900S when your application requires a force output in the 2500 N range at standard factory pressure. If your load demands exceed 3500 N at 0.5 MPa, consider stepping up to the 100 mm bore model (3927 N push at 0.5 MPa). For a lighter, more compact solution, the 63 mm bore provides 1559 N at 0.5 MPa.
At 900 mm stroke, the piston rod is extended significantly. Always evaluate side-load conditions; an unsupported rod at full extension is vulnerable to bending and seal wear. For applications with off-centre loads, use an external linear guide or a guided cylinder to protect the rod and bearing. For a drop-in replacement, match the 80 mm bore, 900 mm stroke, PT3/8 port, built-in magnet (-S), and basic mounting configuration.

- ✓ 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 SC80X900S FAQ
At 0.7 MPa operating pressure, the theoretical push force is 3518 N. The pull force on the retract stroke at the same pressure is 3175 N, due to the area occupied by the 25 mm piston rod.
Yes. The -S suffix indicates a magnetized piston. This allows you to clamp compatible AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the cylinder's tie-rod barrel to detect piston position without additional mounting brackets.
