About the Airtac SAI50 Standard Cylinder SAI50BX65
The AirTAC SAI50X65 is a double-acting ISO 15552 profile cylinder offering 982 N of push force at 0.5 MPa. Its 65 mm stroke is well-suited for short-travel clamping and positioning tasks. The extruded aluminum barrel eliminates tie-rods, providing a clean exterior that resists snagging in tight machine spaces.
Built for demanding environments, this specific configuration features a SUS304 stainless steel piston rod for superior corrosion resistance. It uses PT tapered port threads and lacks a magnet, meaning it is optimized for purely pneumatic operation without external sensor feedback.

Where the Airtac SAI50 Standard Cylinder SAI50BX65 Is Used
Packaging Diverters
Provides rapid 65 mm actuation to push packages between conveyor lanes with 982 N of force.
Stainless Welding Clamps
The SUS304 rod withstands weld spatter and shop debris while holding parts firmly in place.
Short-Stroke Ejectors
Ejects lightweight molded parts from presses quickly using PT-threaded air connections.
Is the Airtac SAI50 Standard Cylinder SAI50BX65 the Right Cylinder?
If you need higher force, stepping up to the 63 mm bore yields 1559 N at 0.5 MPa, while dropping to a 40 mm bore reduces force to 628 N. For this 65 mm stroke, side load is minimal, but always ensure rigid mounting using FA/FB flanges or LB foot brackets to prevent rod binding.
Because this standard SAI variant has no magnet, position sensing is not possible without modification. Furthermore, the adjustable air cushions at both ends only decelerate the piston near stroke end; they do not hold a load. If your application requires position holding upon air loss, consider the SAIL lock variant or an external rod lock.
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.
