About the Airtac SAI50 Standard Cylinder SAI50BX175S
The AirTAC SAI50X175-S is a double-acting ISO 15552 profile-barrel cylinder engineered to deliver 982 N of push force at 0.5 MPa and 1374 N at 0.7 MPa. Its 175 mm stroke is ideal for mid-length actuation in packaging and material handling. The extruded aluminum barrel omits tie rods for a clean exterior.
This specific configuration includes a SUS304 stainless steel piston rod (option B) for superior corrosion resistance in washdown or humid environments. The integrated -S magnet enables direct mounting of CMSE or DMSE sensor switches along the dual grooves on the barrel, ensuring reliable end-of-stroke detection.

Where the Airtac SAI50 Standard Cylinder SAI50BX175S Is Used
Package Sorting Diverter
Uses the 175 mm stroke to push cartons rapidly between sorting lanes on a high-speed conveyor system.
Component Clamping Station
Provides reliable 982 N clamping force at 0.5 MPa to hold aluminum housings securely during CNC machining.
Washdown Gate Actuator
Leverages the SUS304 stainless steel rod to operate fluid control gates in moisture-rich food processing facilities.
Is the Airtac SAI50 Standard Cylinder SAI50BX175S the Right Cylinder?
If your application requires less force, stepping down to a 40 mm bore yields 628 N at 0.5 MPa, while moving up to a 63 mm bore provides 1559 N. For this 175 mm stroke, side loads are moderate, but always ensure the load is guided to prevent rod bearing wear. The PT tapered port threads provide a robust, sealed connection.
Because this is a standard double-acting cylinder, it cannot hold a load if air pressure is lost. If your machinery requires fail-safe position holding, consider the SAIL variant with an air-released lock or use an external pilot-operated check valve. As a true ISO 15552 cylinder, it is dimensionally interchangeable with other standard ISO 15552 profile cylinders.
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 SAI50BX175S FAQ
