About the Airtac SAI40 Standard Air Cylinder SAI40AX75S
The AirTAC SAI40X75-S is a double-acting ISO 15552 profile cylinder engineered with a 40mm bore and 75mm stroke. It generates 628N of push force and 528N of pull force at 0.5 MPa, making it a robust choice for mid-range automation tasks. The extruded aluminum barrel design omits tie-rods, providing a clean exterior that simplifies mounting and sensor placement.
This specific configuration includes a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance compared to standard carbon steel. Equipped with a magnetic piston (-S), it supports direct mounting of CMSE or DMSE reed switches in the dual sensor grooves. Fluid ports feature PT tapered threads, and the cylinder includes adjustable air cushions at both ends to decelerate the piston smoothly.

Where the Airtac SAI40 Standard Air Cylinder SAI40AX75S Is Used
Component Clamping
Ideal for securing medium-weight workpieces during machining, utilizing its 628N push force to maintain rigid hold during secondary operations.
Package Diverting
Provides reliable actuation for diverting mechanisms on packaging lines, where the 75mm stroke quickly pushes cartons onto auxiliary tracks.
Gate Operation
Well-suited for opening and closing small machine guard gates or material hoppers, benefiting from the adjustable end cushions to prevent slamming.
Is the Airtac SAI40 Standard Air Cylinder SAI40AX75S the Right Cylinder?
Select this 40mm bore model when an application requires stepping up from the 32mm version, which offers 402N of push force at 0.5 MPa. If your setup demands even greater thrust, consider moving to the 50mm bore, rated at 982N. The 75mm stroke is optimal for short-travel actuation without introducing excessive rod-bearing bending moments.
Because this is a standard double-acting cylinder, it does not hold its position if air pressure is lost or the control valve is centered; the piston will drift under load. For tasks requiring static holding without continuous live pressure, integrate an external pilot-operated check valve or specify the SAIL variant with an air-released lock. As a true ISO 15552 profile cylinder, it serves as a direct replacement for other ISO 15552 cylinders, matching standard mounting dimensions, PT G1/4 ports, and FA, FB, or LB accessory footprints.
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 SAI40AX75S FAQ
At 0.5 MPa operating pressure, this 40mm bore cylinder provides a push force of 628N and a pull force of 528N. If pressure is increased to 0.7 MPa, the push force rises to 879N.
Yes, the SAI40X75-S is built to standard ISO 15552 dimensions. It is fully interchangeable with other ISO 15552 profile cylinders regarding mounting interfaces, G1/4 port sizing, and accessory compatibility.
