Where the Airtac SAI40 Standard Air Cylinder SAI40BX5 Is Used
Precision Clamping
Ideal for securing small machined components during milling or drilling with rapid 5mm actuation.
Part Ejection
Provides a compact 628N push to eject finished parts from automated presses or molds.
Conveyor Diverting
Acts as a compact stopper or diverter gate for lightweight packaging lines.
Is the Airtac SAI40 Standard Air Cylinder SAI40BX5 the Right Cylinder?
For applications requiring slightly less force, the SAI32X5 offers 402N at 0.5MPa, while stepping up to the SAI50X5 provides 982N. Because the 5mm stroke is exceptionally short, side-load bending is minimal, but precise rod alignment is critical to prevent binding. If the machinery loses air pressure, this standard cylinder will not hold its load; for fail-safe position holding, consider the SAIL or BSAI variants. To match this configuration, specify a 40mm bore, 5mm stroke, PT port, and SUS304 rod material.
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.
