About the Airtac SAI80 Standard Air Cylinder SAI80X20
The AirTAC SAI80X20 is a double-acting ISO 15552 profile cylinder featuring an 80mm bore and a 20mm stroke. It delivers a robust push force of 2513 N at 0.5 MPa, making it highly effective for short-trroke clamping and high-force ejection tasks. The extruded aluminum barrel design omits tie rods, providing a clean exterior that is dimensionally interchangeable with other ISO 15552 cylinders.
This specific configuration features a standard carbon steel piston rod and PT tapered port threads. Because it lacks an integrated magnet (-S), it is not compatible with CMSE or DMSE sensor switches. For environments requiring high-temperature resistance up to 70 C, the standard TPU seals can be substituted with Viton (H) options, though users should verify this during order customization.

Where the Airtac SAI80 Standard Air Cylinder SAI80X20 Is Used
Short-Stroke Pressing
Ideal for high-force pressing and riveting operations where a compact 20mm stroke is sufficient to form or seat components securely.
Product Ejection
Provides rapid, powerful ejection of finished parts from conveyor lines or machining centers using its 2513 N push force.
Heavy-Duty Clamping
Suitable for securing heavy workpieces or pallets during packaging and assembly processes within automated warehousing systems.
Is the Airtac SAI80 Standard Air Cylinder SAI80X20 the Right Cylinder?
With its 80mm bore, this cylinder provides substantial thrust; if you need less force, the 63mm bore offers 1559 N at 0.5 MPa, while the 100mm bore steps up to 3927 N. The 20mm stroke is highly compact, minimizing rod-bearing bending and side-load stresses, making it ideal for tight spaces. Because this is a standard double-acting cylinder, it will drift if air pressure is lost; if your application requires position holding without live pressure, consider the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variants. To ensure proper ISO 15552 replacement matching, verify the 80mm bore, 20mm stroke, G3/8 port, and required mounting accessories like FA flanges or TC trunnions.
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 SAI80 Standard Air Cylinder SAI80X20 FAQ
At an operating pressure of 0.5 MPa, the SAI80X20 generates a push force of 2513 N and a pull force of 2268 N.
Yes, as a true ISO 15552 profile cylinder, its mounting interface dimensions are interchangeable with other ISO 15552 cylinders, though you must verify the 80mm bore, 20mm stroke, and G3/8 port match your existing setup.
