About the Airtac SAI50 Standard Cylinder SAI50BX25
The AirTAC SAI50X25 is a double-acting ISO 15552 profile cylinder engineered for compact actuation, delivering a robust 982N of push force at 0.5 MPa. Its 25mm short stroke is tailored for high-speed clamping and ejection tasks where absolute end-position reach matters more than travel distance.
Built with a SUS304 stainless steel piston rod, this variant provides superior corrosion resistance for humid or washdown settings. It utilizes a PT tapered port thread, and operators can integrate CMSE or DMSE sensors by specifying the -S magnet option on future orders.

Where the Airtac SAI50 Standard Cylinder SAI50BX25 Is Used
Short-Stroke Clamping
Ideal for holding metal workpieces securely during machining operations using its 982N push force.
Product Ejection
Rapidly pushes finished parts off a conveyor belt in tight automated assembly cells.
Gate Diverting
Actuates short diverter gates to route packages on processing lines without occupying much space.
Is the Airtac SAI50 Standard Cylinder SAI50BX25 the Right Cylinder?
Select this 50mm bore when a 40mm cylinder lacks thrust, stepping up from 628N to 982N at 0.5 MPa, but a 63mm bore would be excessive. The 25mm stroke is optimal for tight spaces, and because the travel is so short, rod-bearing bending is negligible. To achieve true ISO 15552 direct interchangeability, match the 50mm bore, 25mm stroke, G1/4 port, and mounting accessory type. Remember that standard air cushions only decelerate the piston near stroke end; if your process must hold a load without continuous air pressure, specify 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.
Airtac SAI50 Standard Cylinder SAI50BX25 FAQ
At 0.5 MPa operating pressure, the SAI50X25 generates a push force of 982N and a pull force of 825N.
Yes, the SAI50X25 is dimensionally interchangeable per ISO 15552, meaning it serves as a direct replacement for other standard profile cylinders with matching mounting interfaces.
