About the Airtac SAI63 Standard Cylinder SAI63X80
The AirTAC SAI63X80 is a double-acting ISO 15552 profile cylinder featuring an 80 mm stroke. It generates 1559 N of push force at 0.5 MPa, making it well-suited for medium-duty industrial actuation. The extruded aluminum barrel design eliminates traditional tie rods while maintaining strict dimensional interchangeability with other ISO 15552 cylinders.
This configuration ships with a standard carbon steel piston rod and PT tapered port threads. Because no magnet is specified, it is optimized for mechanical switching rather than electronic sensor feedback. For high-temperature environments up to 70 C, the standard TPU seals provide reliable service, though Viton (H) alternatives are available if needed.

Where the Airtac SAI63 Standard Cylinder SAI63X80 Is Used
Clamping Mechanisms
Provides 1559 N of thrust at 0.5 MPa for securing medium-weight workpieces during machining operations.
Package Diverters
The 80 mm stroke offers rapid actuation to push or redirect moderate loads on material handling lines.
Gate Control
Ideal for operating safety gates or medium-sized process doors requiring reliable linear motion.
Is the Airtac SAI63 Standard Cylinder SAI63X80 the Right Cylinder?
Select this 63 mm bore when a 50 mm bore (982 N at 0.5 MPa) lacks the necessary push strength, but an 80 mm bore (2513 N at 0.5 MPa) would be excessive overkill. The 80 mm stroke provides rapid extension and retraction cycles within a compact footprint.
As a standard double-acting cylinder, the SAI63X80 relies on continuous air pressure to hold its position; exhausting the air or centering the valve will allow the load to drift. If your application requires fail-safe position holding, consider the SAIL (air-released lock) or BSAI (clamp-lock) variants. This model serves as a direct drop-in replacement for any ISO 15552 cylinder with a 63 mm bore, 80 mm stroke, G3/8 port, and standard 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 SAI63 Standard Cylinder SAI63X80 FAQ
At an operating pressure of 0.5 MPa, this 63 mm bore cylinder provides 1559 N of push force and 1402 N of pull force. At 0.7 MPa, the push force increases to 2182 N.
Yes, the SAI63X80 is a genuine ISO 15552 profile cylinder, meaning its mounting dimensions are fully interchangeable with other ISO 15552 cylinders of the same bore and stroke.
