About the Airtac SAI63 Standard Cylinder SAI63X290
The AirTAC SAI63X290 is a double-acting ISO 15552 profile cylinder engineered to deliver a push force of 1559 N at 0.5 MPa. Its 290 mm stroke provides the extended travel needed for mid-range automation tasks. The extruded aluminum barrel eliminates tie-rods, creating a clean exterior that drops directly into standardized ISO 15552 mounting footprints.
This configuration utilizes a standard carbon steel piston rod and PT tapered port threads. Because it lacks a built-in magnet, position sensing requires external switches rather than the integrated sensor grooves. For applications requiring end-of-stroke locking without continuous air pressure, the related SAIL variant provides a reliable pneumatic lock.

Where the Airtac SAI63 Standard Cylinder SAI63X290 Is Used
Component Ejection
Pushes machined parts out of a CNC workspace with 1559 N of force at 0.5 MPa, utilizing the 290 mm stroke to clear the machining envelope entirely.
Pallet Diverting
Actuates a diverter arm on a packaging line, providing reliable mid-stroke actuation to route boxes without overpowering the mechanical stops.
Gate Operation
Opens and closes medium-sized access gates on automated machinery, using adjustable air cushions at both ends to ensure smooth, impact-free closure.
Is the Airtac SAI63 Standard Cylinder SAI63X290 the Right Cylinder?
Selecting this bore is ideal when a 50mm cylinder's 982 N push at 0.5 MPa is insufficient, but an 80mm unit's 2513 N would be excessive. The 290 mm stroke offers ample extension, though strokes of 300 mm or more require careful attention to side-load management. At this length, an unsupported rod is susceptible to bending under lateral forces, so utilizing an external guide rail or a guided cylinder module is strongly recommended to protect the rod bearing.
Being a true ISO 15552 cylinder, this model is dimensionally interchangeable with other standard profile cylinders. To match existing setups, specify the G3/8 port, the appropriate mounting accessory (such as an LB foot or TC trunnion), and add an -S suffix if internal magnet sensing becomes necessary. Note that standard air cushions only decelerate the piston near stroke ends; they do not hold a load if air pressure is lost.
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 SAI63X290 FAQ
At an operating pressure of 0.5 MPa, this 63mm bore cylinder generates a push force of 1559 N and a pull force of 1402 N. If pressure is increased to 0.7 MPa, the push force rises to 2182 N.
Yes, the SAI63X290 is a genuine ISO 15552 profile cylinder, making its mounting dimensions interchangeable with other standard cylinders. Ensure your setup matches the G3/8 port size and M16x1.5 rod thread before installation.
