About the Airtac SAI40 Standard Air Cylinder SAI40BX5S
The AirTAC SAI40X5-S is a double-acting ISO 15552 profile cylinder engineered for ultra-short travel demands. Operating at 0.5 MPa, it generates 628 N of push force and 528 N of pull force, making it highly effective for compact clamping or indexing tasks. The extruded aluminum barrel design omits tie-rods, providing a clean exterior that fits seamlessly into modern machine layouts.
This specific configuration includes a SUS304 stainless steel piston rod (material code B), offering superior corrosion resistance for washdown or chemically exposed environments. Equipped with a magnet for sensor switches, the barrel features integrated grooves on both sides for direct mounting of CMSE or DMSE reed switches. Fluid porting utilizes a PT tapered thread at the G1/4 port size.

Where the Airtac SAI40 Standard Air Cylinder SAI40BX5S Is Used
Short-Stroke Clamping
Ideal for holding thin workpieces securely in machining fixtures where only 5 mm of travel is required to lock the part in place.
Package Diverting
Provides a rapid 5 mm punch action to deflect lightweight cartons on a high-speed packaging conveyor line.
Valve Actuation
Delivers reliable mechanical force to manually override or pilot process valves in tight, confined equipment spaces.
Is the Airtac SAI40 Standard Air Cylinder SAI40BX5S the Right Cylinder?
Choosing this 5 mm stroke is optimal when only a brief, high-force actuation is needed, such as locking a gate or ejecting a small part. If your application requires even less force, stepping down to the 32 mm bore yields 402 N at 0.5 MPa, while moving up to the 50 mm bore provides 982 N for heavier resistance. Because the stroke is extremely short, side-load stress on the rod bearing is minimal compared to longer strokes.
As a true ISO 15552 cylinder, this unit serves as a direct replacement for any standard 40 mm bore profile cylinder matching those mounting dimensions. It uses a PT G1/4 port and can be paired with FA/FB flanges or LB foot brackets. Note that if air pressure is removed, the piston will not hold its load; for dead-drop prevention without live pressure, consider the SAIL variant with an air-released lock or an external pilot check valve.
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 SAI40BX5S FAQ
At an operating pressure of 0.5 MPa, the SAI40X5-S provides 628 N of push force and 528 N of pull force. If pressure is increased to 0.7 MPa, the push force rises to 879 N.
Yes, because it is built to the ISO 15552 standard, it is dimensionally interchangeable with other ISO 15552 profile cylinders of the same 40 mm bore size. You can swap it directly using existing mounting hardware.
