About the Airtac SAI50 Standard Cylinder SAI50AX500
The AirTAC SAI50X500 is a double-acting ISO 15552 profile cylinder engineered to deliver a push force of 982 N at 0.5 MPa. Its 500 mm stroke is optimal for automated machinery requiring extended linear reach without sacrificing standardized mounting dimensions.
This specific configuration features a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance. It utilizes a PT tapered port thread and lacks a standard magnet, meaning position sensing via CMSE or DMSE switches is not supported without modification.

Where the Airtac SAI50 Standard Cylinder SAI50AX500 Is Used
Material Diversion
Extends 500 mm to actuate large diverter arms on packaging lines, smoothly routing bulky cartons to secondary processing channels.
Long-Reach Clamping
Secures oversized workpieces at extended distances, using its 982 N push force to hold components steady during light machining operations.
Pallet Push-Off
Drives heavy goods off accumulation rollers in distribution hubs, leveraging the long stroke to clear full pallet widths efficiently.
Is the Airtac SAI50 Standard Cylinder SAI50AX500 the Right Cylinder?
If your application requires less force, stepping down to the 40 mm bore offers 628 N at 0.5 MPa, while moving up to the 63 mm bore provides 1559 N for heavier loads. Because this 500 mm stroke generates significant leverage, long unsupported rods are prone to bending under side load; utilizing an external guide rail or a guided cylinder is strongly recommended to prevent premature rod-bearing wear.
This model serves as a direct replacement for any ISO 15552 cylinder matching its 50 mm bore, 500 mm stroke, and G1/4 port. If the machinery must hold a load during air loss, note that the SAI air cushion only decelerates the piston and does not act as a brake; consider the SAIL variant with an air-released lock or an external rod lock for secure positioning.
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 SAI50 Standard Cylinder SAI50AX500 FAQ
At a 0.5 MPa operating pressure, this 50 mm bore cylinder provides a push force of 982 N and a pull force of 825 N. At 0.7 MPa, the push force increases to 1374 N.
Yes, the SAI50X500 is a true ISO 15552 profile cylinder, making it dimensionally interchangeable with older ISO 6431 and VDMA 24562 standards. Just ensure your setup matches the G1/4 port and 50 mm bore dimensions.
