About the Airtac SAI40 Standard Air Cylinder SAI40BX130
The AirTAC SAI40X130 is a double-acting ISO 15552 profile cylinder engineered to deliver 628 N of push force at 0.5 MPa. Its 130 mm stroke provides the precise mid-range extension needed for clamping, lifting, and indexing tasks in tight machinery layouts.
This specific configuration features a SUS304 stainless steel piston rod for superior corrosion resistance in humid or washdown environments. It uses PT tapered port threads and lacks a standard magnet, meaning it is optimized for pure pneumatic actuation without external sensor feedback.

Where the Airtac SAI40 Standard Air Cylinder SAI40BX130 Is Used
Component Clamping
Provides reliable 628 N holding force at 0.5 MPa for securing machined parts during milling or drilling operations.
Package Diverting
The 130 mm stroke actuates diverter arms on packaging lines, offering rapid 30-800 mm/s cycling speeds.
Material Ejection
Uses the 879 N push force at 0.7 MPa to positively eject stamped parts from press dies without damaging surfaces.
Is the Airtac SAI40 Standard Air Cylinder SAI40BX130 the Right Cylinder?
Selecting this 40 mm bore offers a balanced output of 628 N push and 528 N pull at 0.5 MPa, sitting comfortably between the lighter 32 mm bore (402 N) and the heavier 50 mm bore (982 N). Because the stroke is 130 mm, side-load stress on the rod bearing remains minimal, though external guides are always recommended if the load is offset.
As a true ISO 15552 profile cylinder, it serves as a direct replacement for any standard 40 mm bore, 130 mm stroke unit with a G1/4 or PT port and standard mounting accessories like FA flanges or LB foot brackets. Note that if your application requires the piston to hold its position during a complete air pressure loss, a standard SAI will drift; you should specify the SAIL variant with an air-released lock or utilize an external rod lock instead.
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 SAI40BX130 FAQ
At an operating pressure of 0.5 MPa, this 40 mm bore cylinder generates 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, the SAI40X130 is dimensionally interchangeable per ISO 15552 standards. It shares the same 40 mm bore, 130 mm stroke, and G1/4 mounting interface, allowing it to drop into existing ISO 15552 setups seamlessly.
