About the Airtac SAI40 Standard Air Cylinder SAI40BX190S
The AirTAC SAI40X190-S is a double-acting ISO 15552 profile cylinder engineered to deliver 879 N of push force at 0.7 MPa. Its 190 mm stroke provides the precise mid-range extension needed for compact assembly automation and material handling tasks. As a genuine AirTAC component, it ensures dimensional interchangeability with other ISO 15552 standard cylinders.
This specific configuration features a SUS304 stainless steel rod for superior corrosion resistance in wet or mildly chemical environments. It includes a built-in magnet (-S) for seamless integration with CMSE or DMSE sensor switches, which mount directly into the dual grooves on the extruded aluminum barrel. The fluid porting utilizes PT tapered threads, ensuring a robust and leak-free pneumatic connection.

Where the Airtac SAI40 Standard Air Cylinder SAI40BX190S Is Used
Compact Assembly Automation
Provides the precise 190 mm extension and 879 N force required to press small bearings or align components on high-speed manufacturing lines.
Package Diverting
Actuates routing gates on conveyor systems, using the integrated magnet and CMSE sensors to confirm stroke position for pneumatic logic control.
Corrosive Environment Handling
Ideal for food packaging or washdown stations where the SUS304 stainless steel rod prevents rust and ensures long service life.
Is the Airtac SAI40 Standard Air Cylinder SAI40BX190S the Right Cylinder?
Select this 40 mm bore when an application requires more power than a 32 mm bore (which provides only 563 N at 0.7 MPa) but lacks the physical space for a 50 mm option. The 190 mm stroke is well within the 1200 mm maximum standard limit for this bore size, making it highly versatile for standard duty cycles.
Because the stroke is under 300 mm, rod-bearing bending from side loads is minimal, though external guides are still recommended if absorbing heavy lateral moments. Note that the adjustable air cushions at both ends only decelerate the piston near stroke end; they do not hold a load. If your system loses air pressure, the rod will drift. For position-holding requirements without live pressure, specify the SAIL (air-released lock) or BSAI (clamp-lock) variant instead.
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 SAI40 Standard Air Cylinder SAI40BX190S FAQ
At a standard operating pressure of 0.7 MPa, this 40 mm bore cylinder generates 879 N of push force and 738 N of pull force. At 0.5 MPa, it provides 628 N push and 528 N pull.
Yes. The SAI40X190-S is a true ISO 15552 profile cylinder, meaning its mounting dimensions are fully interchangeable with other ISO 15552 cylinders. You can drop it into existing setups using standard FA, FB, LB, or TC mounting accessories.
