About the Airtac SAI40 Standard Air Cylinder SAI40X45S
The AirTAC SAI40X45-S is a double-acting ISO 15552 profile cylinder with a 40mm bore and 45mm stroke. It delivers 628N of push force at 0.5 MPa, making it well-suited for short-stroke clamping and ejection tasks. The extruded aluminum barrel design omits tie rods for a clean exterior.
This configuration includes a magnetic piston (-S) for position sensing and uses a standard carbon steel piston rod. The standard seals are TPU, but Viton (H) options are available for higher temperature environments.

Where the Airtac SAI40 Standard Air Cylinder SAI40X45S Is Used
Short-Stroke Clamping
Ideal for holding parts securely during machining or assembly operations within a 45mm travel range.
Package Ejection
Provides reliable 628N push force to eject completed goods or divert items on a conveyor line.
Gate Diverter
Actuates short-flow gates to route products, utilizing the integrated magnet for precise end-position confirmation.
Is the Airtac SAI40 Standard Air Cylinder SAI40X45S the Right Cylinder?
If an application requires less force, stepping down to a 32mm bore yields 402N at 0.5 MPa, whereas moving up to a 50mm bore provides 982N for heavier loads. This 45mm stroke is non-standard but falls within the standard manufacturing range, offering a compact footprint for tight machinery.
Being a genuine AirTAC component, it ensures dimensionally interchangeable mounting per ISO 15552. Note that the adjustable air cushions only decelerate the piston near stroke ends; they do not hold a load if air pressure is lost. For positive holding, consider the SAIL or BSAI variants.
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 SAI40X45S FAQ
At 0.5 MPa, the push force is 628N and the pull force is 528N. At 0.7 MPa, the push force increases to 879N.
Yes, the SAI series is a true ISO 15552 profile cylinder. It is dimensionally interchangeable with other ISO 15552 cylinders, provided the 40mm bore, 45mm stroke, and G1/4 port match your existing interface.
