About the Airtac SAI63 Standard Cylinder SAI63X290S
The AirTAC SAI63X290-S is a double-acting ISO 15552 profile cylinder engineered to deliver 1559 N of push force at 0.5 MPa. Its 290 mm stroke provides the extended travel needed for mid-range automation tasks. Built with a standard carbon steel piston rod, it withstands rigorous industrial cycling while maintaining a 30-800 mm/s operating speed range.
Because this variant includes the -S magnet option, it integrates seamlessly with CMSE and DMSE sensor switches mounted directly into the extruded aluminum barrel's dual side grooves. This configuration uses PT tapered port threads and features adjustable air cushions at both ends to decelerate the piston smoothly, protecting your equipment from end-of-stroke impact.

Where the Airtac SAI63 Standard Cylinder SAI63X290S Is Used
Package Diversion
Extends 290 mm to push medium-weight cartons off a main conveyor belt with 1559 N of force at 0.5 MPa operating pressure.
Component Pressing
Provides reliable downward clamping force for seating bearings or pins into housings during automated assembly processes.
Gate Actuation
Cycles heavy machine guarding or material flow gates, utilizing adjustable air cushions to soften the impact at full extension.
Is the Airtac SAI63 Standard Cylinder SAI63X290S the Right Cylinder?
If your application requires less push force, stepping down to the 50 mm bore yields 982 N at 0.5 MPa, while moving up to the 80 mm bore provides 2513 N for heavier loads. At 290 mm of stroke, the unsupported rod length is significant; side loads can cause rod-bearing bending. Use external guide rails or a guided cylinder to prevent premature seal wear and binding.
This profile cylinder is dimensionally interchangeable per ISO 15552, serving as a drop-in replacement for other ISO 15552 cylinders with a 63 mm bore, 290 mm stroke, G3/8 port, and standard mounting accessories like FA flanges or TC trunnions. Note that a standard SAI relies on continuous air pressure to move and hold loads; if pressure is lost, the piston will drift. For dead-end holding without live pressure, specify the SAIL lock variant.
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 SAI63X290S FAQ
At 0.5 MPa, the SAI63X290-S provides a push force of 1559 N and a pull force of 1402 N. If you increase the operating pressure to 0.7 MPa, the push force rises to 2182 N.
Yes, the SAI is a true ISO 15552 profile cylinder. It is dimensionally interchangeable with other ISO 15552 cylinders of the same 63 mm bore and 290 mm stroke, requiring no mounting footprint modifications.
