About the Airtac SAI50 Standard Cylinder SAI50BX120
The AirTAC SAI50X120 is a double-acting ISO 15552 profile cylinder offering a practical 120 mm stroke. It generates 982 N of push force and 825 N of pull force at 0.5 MPa, fitting perfectly into medium-duty automation tasks.
Built with a SUS304 stainless steel rod for superior corrosion resistance, this model utilizes PT tapered port threads. The extruded aluminum barrel includes dual sensor grooves, allowing easy integration of CMSE or DMSE switches when a magnet is added.

Where the Airtac SAI50 Standard Cylinder SAI50BX120 Is Used
Packaging Lines
Drives product diverters and sorting gates with reliable 982 N force at 0.5 MPa.
Assembly Stations
Clamps and positions medium-weight components accurately over a 120 mm travel range.
Material Handling
Lifts and transfers packaged goods using the durable SUS304 stainless steel rod.
Is the Airtac SAI50 Standard Cylinder SAI50BX120 the Right Cylinder?
Providing 982 N at 0.5 MPa, this 50 mm bore sits comfortably between the 40 mm (628 N) and 63 mm (1559 N) options. Choose the SAI50X120 when your application requires moderate force without the bulk of larger cylinders.
Because this is a double-acting cylinder, it relies on continuous air pressure to hold position. If your process requires fail-safe load holding during pressure loss, consider the SAIL (air-released lock) or BSAI (clamp-lock) variants. To match this unit for an ISO 15552 direct replacement, specify the 50 mm bore, 120 mm stroke, PT G1/4 port, and your preferred mounting accessory like an FA flange or LB foot.
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 SAI50BX120 FAQ
At 0.5 MPa, the SAI50X120 generates 982 N of push force and 825 N of pull force. At 0.7 MPa, the push force increases to 1374 N.
Yes, the SAI50X120 is dimensionally interchangeable per ISO 15552. Ensure your replacement matches the 50 mm bore, 120 mm stroke, and G1/4 PT port for a seamless direct fit.
