About the Airtac SAI40 Standard Air Cylinder SAI40BX175
The AirTAC SAI40X175 is a double-acting ISO 15552 profile cylinder engineered to deliver 879 N of push force at 0.7 MPa. Its 175 mm stroke provides the extended travel necessary for mid-range positioning tasks. Built with an extruded aluminum barrel, this tie-rod-less design ensures standardized mounting dimensions for straightforward machinery integration.
To suit demanding environments, this configuration utilizes a SUS304 stainless steel piston rod (option B) for superior corrosion resistance. The pneumatic supply connects via a tapered PT G1/4 port. While adjustable air cushions at both ends manage end-of-stroke deceleration, this standard actuator does not hold position upon air loss; for fail-safe load holding, consider the SAIL locking variant.

Where the Airtac SAI40 Standard Air Cylinder SAI40BX175 Is Used
Package Diverting
Provides the 879 N force and 175 mm travel needed to push packages smoothly across sorting conveyor belts.
Component Clamping
Secures workpieces during machining operations, using its stainless steel rod to resist minor splatter.
Gate Control
Actuates access gates on storage enclosures, offering reliable mid-stroke extension in logistics hubs.
Is the Airtac SAI40 Standard Air Cylinder SAI40BX175 the Right Cylinder?
Stepping up to the 50 mm bore raises the 0.5 MPa thrust to 982 N if your application requires more push power, while dropping to a 32 mm bore reduces it to 402 N for lighter duty. At 175 mm of travel, side loads can accelerate wear on the rod bearing; utilizing an external guide rail or a guided cylinder helps prevent rod deflection under offset loads.
As a dimensionally interchangeable ISO 15552 actuator, it serves as a direct replacement matching the 40 mm bore, 175 mm stroke, PT G1/4 port, and standard mounting accessories. Note that because a magnet is not specified, this unit cannot host CMSE or DMSE position sensors.
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.
