About the Airtac SAI40 Standard Air Cylinder SAI40X105
The AirTAC SAI40X105 is a double-acting ISO 15552 profile cylinder featuring a 40mm bore and 105mm stroke. It delivers a push force of 628N at 0.5 MPa and 879N at 0.7 MPa, making it well-suited for medium-duty handling tasks.
This extruded aluminum barrel design omits tie rods and includes dual sensor grooves for CMSE or DMSE switches if a magnet is specified later. The standard configuration uses a carbon steel piston rod and PT tapered port threads to ensure robust, leak-free pneumatic connections.

Where the Airtac SAI40 Standard Air Cylinder SAI40X105 Is Used
Parts Clamping
Ideal for holding medium workpieces securely in place during machining or assembly operations using 879N of thrust.
Package Diverting
Provides reliable actuation for diverting small to medium packages on automated material handling lines.
Gate Control
Operates safety gates and machine guarding doors with a compact 105mm stroke that saves machine footprint.
Is the Airtac SAI40 Standard Air Cylinder SAI40X105 the Right Cylinder?
If your application requires less force, stepping down to a 32mm bore yields 563N at 0.7 MPa, while moving up to a 50mm bore provides 1374N at 0.7 MPa for heavier loads. Because this 105mm stroke is relatively short, rod-bearing bending is minimal, but always mount using standard ISO 15552 accessories like FA flanges or LB foot brackets.
Remember that the adjustable air cushions only decelerate the piston near the stroke ends; they do not hold a load if air pressure is lost. For drop-in replacements, verify the 40mm bore, 105mm stroke, G1/4 port, and M12x1.25 rod thread match your existing mounting interface.
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 SAI40X105 FAQ
