About the Airtac SAI50 Standard Cylinder SAI50X80
The AirTAC SAI50X80 is a double-acting profile cylinder with a 50mm bore and an 80mm stroke, delivering a push force of 982 N at 0.5 MPa. It features an extruded aluminum barrel and conforms exactly to the ISO 15552 mounting interface, ensuring drop-in compatibility with other standard profile cylinders. This specific 80mm stroke is ideal for short-travel clamping and ejection tasks.
To suit various environmental demands, the piston rod is available in standard carbon steel, as well as SUS420J2 or SUS304 stainless steel. Furthermore, the standard TPU seals can be swapped for Viton (H) for high-temperature applications up to +70 C, or NBR (N) for specific fluid resistance.

Where the Airtac SAI50 Standard Cylinder SAI50X80 Is Used
Short-Stroke Clamping
Provides 982 N of clamping force at 0.5 MPa, ideal for securing medium-sized workpieces during machining or welding operations.
Product Ejection
The 80mm stroke offers rapid retraction and extension to push finished parts off a conveyor line without occupying excessive machine footprint.
Packaging Diverter
Suitable for actuating lightweight diverter gates in packaging lines where a compact 50mm bore and short travel distance are required.
Is the Airtac SAI50 Standard Cylinder SAI50X80 the Right Cylinder?
If your application requires less force, stepping down to a 40mm bore yields 628 N at 0.5 MPa, while moving up to a 63mm bore provides 1559 N. For this 80mm stroke, side load is minimal, but always ensure the load is axially aligned to prevent premature rod-bearing wear. The cylinder uses a PT tapered G1/4 port and accepts standard ISO 15552 mounting accessories like FA flanges or TC trunnions. Since a plain SAI50X80 does not include a magnet, add the -S suffix if you need to mount CMSE or DMSE reed sensors in the dual side grooves.
Note that the adjustable air cushions at both ends only decelerate the piston near the stroke end; they do not lock the load. If your system loses air pressure, the piston will drift. For position holding without live pressure, consider the SAIL pneumatic lock variant or an external pilot-operated check valve.
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 SAI50 Standard Cylinder SAI50X80 FAQ
At a standard operating pressure of 0.5 MPa, the SAI50X80 generates a push force of 982 N and a pull force of 825 N. At 0.7 MPa, the push force increases to 1374 N.
Yes, the SAI50X80 is a genuine ISO 15552 profile cylinder, making it dimensionally interchangeable with other ISO 15552 cylinders of the same bore size. You can use the existing mounting accessories and rod connection points.
