About the Airtac SAI50 Standard Cylinder SAI50BX145S
The AirTAC SAI50X145-S is a double-acting ISO 15552 profile cylinder engineered to deliver 982 N of push force at 0.5 MPa. Its 145 mm stroke provides an optimal mid-range extension for general automation tasks.
This specific configuration features a SUS304 stainless steel piston rod for superior corrosion resistance, a PT tapered port thread, and an integrated magnet for direct compatibility with CMSE and DMSE sensor switches.

Where the Airtac SAI50 Standard Cylinder SAI50BX145S Is Used
Packaging Equipment
Drives sealing jaws and product diverters with reliable 982 N thrust at 0.5 MPa operating pressure.
Material Handling
Pushes medium-weight packages off a conveyor line using the 145 mm stroke and SUS304 rod.
Assembly Automation
Actuates clamping fixtures and positioning stops, utilizing the integrated magnet for end-of-stroke confirmation.
Is the Airtac SAI50 Standard Cylinder SAI50BX145S the Right Cylinder?
Choose this 50 mm bore when an application requires stepping up from a 40 mm bore (628 N at 0.5 MPa) but does not need the heavier 1559 N output of a 63 mm cylinder. As a dimensionally interchangeable ISO 15552 profile cylinder, it serves as a direct replacement for other standard 50 mm bore, 145 mm stroke cylinders with G1/4 ports and standard mounting accessories like LB or FA.
Because the standard SAI lacks a locking mechanism, the piston will drift if air pressure is lost. For applications requiring position holding without live pressure, consider the SAIL 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.
Airtac SAI50 Standard Cylinder SAI50BX145S FAQ
At 0.5 MPa, this 50 mm bore cylinder provides 982 N of push force and 825 N of pull force. If you increase the pressure to 0.7 MPa, the push force rises to 1374 N.
Yes, the SAI50X145-S is a genuine ISO 15552 profile cylinder. Its standardized mounting dimensions, G1/4 ports, and 145 mm stroke make it dimensionally interchangeable with other ISO 15552 cylinders.
