About the Airtac SAI40 Standard Air Cylinder SAI40X95S
The AirTAC SAI40X95-S is a double-acting ISO 15552 profile cylinder with a 40mm bore and 95mm stroke. It delivers 628N of push force and 528N of pull force at 0.5 MPa, making it well-suited for medium-duty handling tasks. The extruded aluminum barrel design omits tie rods, providing a clean exterior that simplifies mounting accessory installation.
This specific configuration includes a magnetic piston, allowing seamless integration with CMSE or DMSE reed switches for precise end-of-stroke detection. The standard carbon steel piston rod offers robust durability, while the integrated adjustable air cushions at both ends effectively absorb impact energy. PT tapered port threading ensures a tight, reliable pneumatic connection.

Where the Airtac SAI40 Standard Air Cylinder SAI40X95S Is Used
Component Clamping
Provides reliable 628N clamping pressure at 0.5 MPa for holding aluminum or steel workpieces securely during machining and drilling operations.
Package Diverting
Actuates a 95mm stroke to push or sort medium-weight packages and cartons along a conveyor line in material handling systems.
Gate Control
Drives small access gates and machine guards, utilizing the magnetic piston and CMSE switches to confirm open and closed positions.
Is the Airtac SAI40 Standard Air Cylinder SAI40X95S the Right Cylinder?
Choose this 40mm bore when an application requires more thrust than the 32mm variant (which provides 402N push at 0.5 MPa) but where the physical footprint and 879N push force of the 63mm bore would be excessive. The 95mm stroke is optimal for short-travel pick-and-place movements. Because the stroke is under 300mm, rod bending under side load is minimal, though external guides are still recommended for heavy off-center loads.
This cylinder serves as a drop-in replacement for any standard ISO 15552 profile cylinder with matching 40mm bore, 95mm stroke, and G1/4 port dimensions. It utilizes a magnetic piston for sensor tracking. If your machinery requires the load to stay fixed in place after air pressure is removed or exhausted, note that the standard air cushion only decelerates the piston and does not act as a brake; you should specify the SAIL variant with an air-released lock or use an external rod lock.
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 SAI40X95S FAQ
At a standard operating pressure of 0.5 MPa, this 40mm bore cylinder generates 628N of push force and 528N of pull force. At the maximum rated pressure of 1.0 MPa, it can reach a theoretical maximum of 128 kgf.
Yes, the SAI40X95-S is dimensionally interchangeable per ISO 15552 standards. You can directly replace other ISO 15552 profile cylinders with the same 40mm bore, 95mm stroke, and G1/4 port size.
