About the Airtac SAI40 Standard Air Cylinder SAI40BX150SH
The AirTAC SAI40X150-S is a double-acting ISO 15552 profile cylinder engineered for rigorous automation environments. Delivering a push force of 879 N at 0.7 MPa, this 40 mm bore unit features a 150 mm stroke that provides ample extension for mid-range positioning tasks. The extruded aluminum barrel omits tie-rods, ensuring a clean profile that drops directly into standardized ISO 15552 mounting footprints.
This specific configuration incorporates a SUS304 stainless steel rod for superior corrosion resistance and a Viton (FKM) seal, expanding the operating temperature range to accommodate elevated thermal loads up to +70 C and beyond standard NBR limits. Equipped with a factory magnet (-S), the barrel integrates dual sensor grooves designed to seamlessly accept CMSE or DMSE reed switches for precise end-of-stroke detection.

Where the Airtac SAI40 Standard Air Cylinder SAI40BX150SH Is Used
Hot End Component Handling
The Viton seals and SUS304 rod make this cylinder ideal for handling parts near ovens or in elevated ambient temperatures where standard TPU seals would degrade.
Medium Duty Diverting
Providing 628 N of push force at 0.5 MPa, it easily powers diverter arms and sorting gates on packaging lines operating at speeds up to 800 mm/s.
Chemical Resistant Actuation
The stainless steel rod offers robust defense against chemical washdowns, making it suitable for actuating valves and doors in light chemical processing zones.
Is the Airtac SAI40 Standard Air Cylinder SAI40BX150SH the Right Cylinder?
Select this 40 mm bore when an application requires stepping up from the 32 mm class (which provides 563 N at 0.7 MPa) to achieve higher thrust without jumping to the heavier 50 mm profile. The 150 mm stroke offers extended travel while remaining well within standard dimensional limits, making it highly versatile for general automation. Because the stroke exceeds 300 mm, side-load management is not a primary concern here, but standard alignment practices still apply to maximize rod-bearing life.
This cylinder utilizes PT tapered port threading (G1/4) and is fully interchangeable with other ISO 15552 cylinders via standard FA, FB, LB, or TC mounting accessories. Note that the adjustable air cushions at both ends only decelerate the piston near stroke completion; they do not lock the rod. If your process requires the load to remain stationary upon loss of air pressure, integrate an external pilot-operated check valve or specify an SAIL locking variant.
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 SAI40BX150SH FAQ
At a standard operating pressure of 0.7 MPa, the 40 mm bore generates a push force of 879 N and a pull force of 528 N. At 0.9 MPa, the push force increases to 1130 N.
Yes, the SAI40X150-S is dimensionally interchangeable per ISO 15552. You can drop it into existing ISO 15552 mounting accessories like FA flanges or TC trunnions without modifying the machine frame.
