About the Airtac SC80 Standard Cylinder SC80X900
The SC80X900 is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining an 80 mm bore with a 900 mm stroke. At 0.5 MPa it generates 2513 N of push force and 2268 N on the pull stroke, scaling up to 4523 N at the maximum operating pressure of 0.9 MPa.
This model uses a 25 mm diameter piston rod with an M20x1.5 male thread and a PT3/8 port. The body length A is 182 mm, giving a total extended length of approximately 1082 mm. It features an adjustable air cushion (28 mm length) to decelerate the piston quietly at each end of the stroke.

Where the Airtac SC80 Standard Cylinder SC80X900 Is Used
Long-Reach Material Transfer
Pushes or pulls parts across a 900 mm span on packaging or assembly conveyors, using the full stroke for bin-picking or diverting operations.
Vertical Panel Pressing
Applies 2513 N of consistent clamping force to glue or laminate large panels in furniture manufacturing, with the adjustable cushion softening the end-of-stroke impact.
Hopper Gate Actuation
Opens and closes a slide gate on a bulk material hopper. The 900 mm stroke provides full clearance, while the 25 mm rod resists buckling under compressive loads.
Is the Airtac SC80 Standard Cylinder SC80X900 the Right Cylinder?
Choose the SC80X900 when your application needs the 2513 N push force class at standard plant pressure. If you require more force, stepping up to the SC100 bore delivers 3927 N at 0.5 MPa; for a lighter, more compact solution, the SC63 bore provides 1559 N.
For this 900 mm stroke, carefully evaluate side-loading conditions. A long, unsupported 25 mm rod can bend under lateral force, causing premature bearing and seal wear. Use an external linear guide or a guided cylinder to absorb the side load, ensuring the rod sees only axial force. When replacing an existing cylinder, match five points: 80 mm bore, 900 mm stroke, PT3/8 port thread, basic (no bracket) mounting, and the absence of a magnet.
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 SC80X900 FAQ
At the standard 0.5 MPa operating pressure, 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 increases to 4523 N.
No, it is not designed for direct side loads. The 25 mm rod is long at this stroke and will bend if subjected to lateral force. You must use an external linear guide rail or rod support to absorb any side load and protect the rod bearings and seals.
