About the Airtac SAI40 Standard Air Cylinder SAI40AX95
The AirTAC SAI40X95 is a double-acting ISO 15552 profile cylinder engineered for standardized automation setups. Delivering a push force of 628 N at 0.5 MPa and 879 N at 0.7 MPa, this 40mm bore unit is tailored for mid-range actuation tasks requiring a 95mm stroke.
Built with a SUS420J2 stainless steel piston rod (material code A), it provides excellent corrosion resistance and structural durability. The barrel features dual-sided sensor grooves for CMSE or DMSE switches, though adding a magnet (-S) is required to enable position detection.

Where the Airtac SAI40 Standard Air Cylinder SAI40AX95 Is Used
Component Clamping
Secures aluminum engine blocks during CNC machining operations, utilizing its 879N thrust at 0.7 MPa to hold workpieces firmly against locators.
Package Diverting
Actuates a 95mm pusher arm to sort medium-weight packages on a packaging line, providing enough stroke to clear the conveyor belt path.
Gate Control
Operates a pneumatic flow-control gate on an assembly line, cycling rapidly within the 30-800 mm/s speed range to regulate part feeding.
Is the Airtac SAI40 Standard Air Cylinder SAI40AX95 the Right Cylinder?
Selecting this bore size is optimal when a 32mm bore (402 N push at 0.5 MPa) lacks the necessary thrust for your tooling, but a 50mm bore (982 N push at 0.5 MPa) would be physically oversized. The 95mm stroke is a non-standard intermediate length, falling between the 80mm and 100mm standard increments, making it ideal for applications requiring precise intermediate travel without custom spacers.
For interchangeability, this model aligns with ISO 15552 mounting interfaces, utilizing a PT tapered G1/4 port and standard M12x1.25 rod threading. If your machinery experiences sudden air loss, note that the standard adjustable air cushions only decelerate the piston at stroke ends and do not function as a locking mechanism to hold loads in place.
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 SAI40AX95 FAQ
At a standard operating pressure of 0.7 MPa, the push force is 879 N and the pull force is 528 N. If operated at 0.5 MPa, the push force drops to 628 N.
Yes, the SAI40X95 is dimensionally interchangeable per ISO 15552 standards. It shares the same mounting footprint and G1/4 port locations as other ISO 15552 profile cylinders, allowing for seamless direct replacement.
