About the Airtac SAI40 Standard Air Cylinder SAI40AX195S
The AirTAC SAI40X195-S is a double-acting ISO 15552 profile cylinder featuring a 40mm bore and 195mm stroke. It delivers a push force of 628 N at 0.5 MPa, making it well-suited for medium-duty handling tasks. The extruded aluminum barrel design integrates sensor grooves on both sides for straightforward position feedback.
This specific configuration includes a -S magnet for use with CMSE and DMSE reed switches. It also features an A-code SUS420J2 stainless steel piston rod for enhanced corrosion resistance, and utilizes PT tapered port threads for a robust pneumatic connection.

Where the Airtac SAI40 Standard Air Cylinder SAI40AX195S Is Used
Material Handling
Ideal for pushing packages or diverting products on a conveyor line where 628 N of push force at 0.5 MPa is sufficient for smooth operation.
Small Pressing
Provides reliable downward pressure for light assembly tasks or component seating without requiring a massive footprint.
Pick and Place
The integrated -S magnet allows for precise end-of-stroke detection using CMSE sensors, ensuring accurate vertical lifting in automated retrieval systems.
Is the Airtac SAI40 Standard Air Cylinder SAI40AX195S the Right Cylinder?
Choose this 40mm bore when a 32mm cylinder lacks thrust (the 32mm bore provides 402 N at 0.5 MPa) but a 50mm bore (982 N at 0.5 MPa) would be physical overkill. The 195mm stroke is a standard length, falling safely below the 1200mm maximum for this bore size, so no made-to-order lead time is required.
Because this is a standard double-acting cylinder, it will not hold a load if air pressure is lost or the valve is centered; the piston will drift. For applications requiring intermediate position holding or drop protection, consider the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variants. To replace an existing unit, match the 40mm bore, 195mm stroke, PT G1/4 port, and mounting accessories like FA flanges or LB foot mounts.
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 SAI40AX195S FAQ
At a standard operating pressure of 0.5 MPa, the SAI40X195-S provides a push force of 628 N and a pull force of 528 N. At 0.7 MPa, the push force increases to 879 N.
Yes, the SAI40X195-S is dimensionally interchangeable per ISO 15552 standards. You can use it as a direct replacement for other ISO 15552 profile cylinders by matching the 40mm bore, 195mm stroke, and G1/4 port size.
