About the Airtac SAI40 Standard Air Cylinder SAI40BX230
The AirTAC SAI40X230 is a double-acting profile cylinder built to ISO 15552 dimensional standards, providing a direct mounting interface for machinery needing standardized part replacement. It yields 628 N of push force and 528 N of pull force at a 0.5 MPa operating pressure, making it well-suited for medium-duty handling tasks over its 230 mm stroke.
This specific configuration features a SUS304 stainless steel piston rod for superior corrosion resistance in humid or chemically exposed settings. The extruded aluminum barrel includes integrated sensor grooves on both sides, allowing direct mounting of DMSE or CMSE switches if a magnet is added later.

Where the Airtac SAI40 Standard Air Cylinder SAI40BX230 Is Used
Package Diversion
Provides the 528 N pull force needed to actuate routing gates on high-speed packaging lines over a 230 mm travel distance.
Clamp and Release
Ideal for holding aluminum or composite workpieces during light CNC machining, utilizing its 879 N push force at 0.7 MPa.
Vertical Lifting
Raises lightweight tote boxes in storage retrieval systems, where the SUS304 rod prevents corrosion in fluctuating warehouse humidity.
Is the Airtac SAI40 Standard Air Cylinder SAI40BX230 the Right Cylinder?
Choose this 40 mm bore when a 32 mm bore (402 N push at 0.5 MPa) lacks the necessary thrust, but a 50 mm bore (982 N push) would be physically oversized. The 230 mm stroke is a standard length, but because it exceeds 200 mm, you must account for potential rod-bearing bending under heavy side loads; utilizing an external guide rail or a twin-guide cylinder is recommended to prevent premature wear.
To match this part exactly for an ISO 15552 interchange, specify the 40 mm bore, 230 mm stroke, PT tapered port thread, G1/4 port size, and your required mounting accessory such as an LB foot or TC trunnion. Note that a standard SAI does not hold its position upon air loss; if gravity or drift must be prevented, select the SAIL locking variant 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.
