About the Airtac SAI40 Standard Air Cylinder SAI40X110
The AirTAC SAI40X110 is a double-acting ISO 15552 profile cylinder offering a 40mm bore and 110mm stroke. It provides 628N of push force at 0.5 MPa, making it well-suited for medium-duty positioning tasks.
This model features a standard carbon steel piston rod and a PT tapered port thread. The extruded aluminum barrel includes dual sensor grooves, allowing direct mounting of CMSE or DMSE switches when a magnet is specified.

Where the Airtac SAI40 Standard Air Cylinder SAI40X110 Is Used
Component Clamping
Secures medium-weight machined parts during secondary milling or drilling operations with 879N of force at 0.7 MPa.
Package Diverting
Actuates routing gates on assembly lines to direct moderately sized cartons to specific processing lanes.
Material Ejection
Pushes completed molded products out of press dies using a 110mm stroke extension cycle.
Is the Airtac SAI40 Standard Air Cylinder SAI40X110 the Right Cylinder?
If your application requires less force, stepping down to the 32mm bore yields 402N at 0.5 MPa. For heavier loads, the 50mm bore provides 982N. Because this is a double-acting cylinder, it relies on continuous air pressure to maintain position; if pressure drops, the rod will drift. For fail-safe holding, consider the SAIL variant with an air-released lock. This unit mounts via standard ISO 15552 accessories like FA flanges or TC trunnions.
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 SAI40X110 FAQ
