About the Airtac SAI40 Standard Air Cylinder SAI40BX105
The AirTAC SAI40X105 is a double-acting ISO 15552 profile cylinder offering a 40mm bore and 105mm stroke. It generates 628N of push force at 0.5 MPa, making it well-suited for medium-duty handling tasks.
Built with a SUS304 stainless steel rod and PT tapered port threads, this model handles demanding environments. The extruded aluminum barrel includes dual sensor grooves for CMSE or DMSE switches, though a magnet is not specified for this configuration.

Where the Airtac SAI40 Standard Air Cylinder SAI40BX105 Is Used
Component Clamping
Secures medium-weight machined parts during secondary milling or drilling operations.
Package Diverting
Actuates diverter arms on packaging lines to route boxes to specific processing lanes.
Pallet Stopping
Controls pallet flow on roller conveyors by deploying a physical stop block.
Is the Airtac SAI40 Standard Air Cylinder SAI40BX105 the Right Cylinder?
Choose this 40mm bore when 628N at 0.5 MPa is sufficient, stepping down from the 50mm bore (982N) for tighter spaces, or up from the 32mm bore (402N) when extra thrust is needed. As an ISO 15552 profile cylinder, it serves as a direct replacement matching standard mounting dimensions and G1/4 ports.
Note that air cushions only decelerate the piston near stroke ends and do not hold loads. If your application requires position holding without live air pressure, consider the SAIL locking variant or 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.
