About the Airtac SAI50 Standard Cylinder SAI50BX225
The AirTAC SAI50X225 is a double-acting ISO 15552 profile cylinder engineered to deliver 982 N of push force at 0.5 MPa. Its 225 mm stroke provides the extended travel needed for mid-range material handling and assembly automation. Built with an extruded aluminum barrel, this tie-rod-less design ensures rigid performance while dropping directly into standardized ISO 15552 mounting footprints.
This specific configuration features a SUS304 stainless steel piston rod (material code B) for superior corrosion resistance in humid or washdown environments. Fluid ports utilize a PT tapered thread type. Because a magnet is not specified, this unit operates without integrated position sensing; add the -S option if your application requires CMSE or DMSE reed switches.

Where the Airtac SAI50 Standard Cylinder SAI50BX225 Is Used
Component Assembly
Drives 225 mm linear motions to press and seat mid-sized mechanical components with 982 N of push force at 0.5 MPa.
Product Diversion
Actuates sorting gates along packaging lines, utilizing the SUS304 rod to withstand occasional moisture exposure during washdowns.
Vertical Lifting
Elevates lightweight product trays; pair with an external check valve to prevent drift if compressed air pressure is lost.
Is the Airtac SAI50 Standard Cylinder SAI50BX225 the Right Cylinder?
Select this 50 mm bore when a 32 mm bore (402 N push at 0.5 MPa) lacks the necessary thrust, but an 63 mm bore (1559 N push at 0.5 MPa) would be physically oversized. The 225 mm stroke falls below the 300 mm side-load threshold, making it well-suited for direct mounting without auxiliary guides in standard pick-and-place tasks.
If your machinery loses air pressure, the standard adjustable air cushions at both ends only decelerate the piston near stroke end and will not hold a suspended load. For vertical applications requiring fail-safe position holding, specify the SAIL variant with an air-released lock or utilize an external pilot-operated check valve. This cylinder is fully interchangeable with other ISO 15552 profile cylinders via standard FA, FB, or TC mounting accessories.
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 SAI50BX225 FAQ
At 0.5 MPa operating pressure, this 50 mm bore cylinder provides 982 N of push force and 825 N of pull force. At 0.7 MPa, the push force increases to 1374 N.
Yes, the SAI50X225 is dimensionally interchangeable per ISO 15552. You can drop it into existing foot, flange, or trunnion mounts designed for other ISO 15552 profile cylinders without modifying the frame.
