About the Airtac SAI40 Standard Air Cylinder SAI40BX230S
The AirTAC SAI40X230-S is a double-acting ISO 15552 profile cylinder offering 628N of push force and 528N of pull force at 0.5 MPa. Its 230mm stroke is well-suited for medium-travel indexing and automated ejection tasks. The extruded aluminum barrel design omits tie rods, providing a clean exterior that simplifies cleaning and reduces debris buildup in demanding environments.
This specific configuration includes a SUS304 stainless steel rod (option B) for superior corrosion resistance in wet or mildly chemical atmospheres. It also features a built-in magnet (-S) for use with CMSE and DMSE sensor switches, which mount directly into the dual grooves on the barrel. Porting utilizes PT tapered threads, ensuring a robust, mechanically sealed pneumatic connection.

Where the Airtac SAI40 Standard Air Cylinder SAI40BX230S Is Used
Package Sorting Diverter
Ideal for pushing medium-weight parcels on a sorting line, utilizing the 230mm stroke to fully clear the conveyor lane.
Component Ejection
Provides reliable ejection of machined parts from a fixture, where the SUS304 rod resists coolant mist and shop moisture.
Pallet Stopper
Acts as a pneumatic stop for incoming pallets on a low-profile transfer line, absorbing impact with adjustable end cushions.
Is the Airtac SAI40 Standard Air Cylinder SAI40BX230S the Right Cylinder?
Choose this 40mm bore when an application requires more thrust than the 32mm bore (402N at 0.5 MPa) but does not warrant the larger footprint and air consumption of the 50mm bore (982N at 0.5 MPa). The 230mm stroke provides ample travel for automated sorting and packaging machinery.
Because the 230mm stroke exceeds 300mm? No, but at this length managing side load is still prudent; use an external guide rail to prevent rod-bearing bending if the load is not perfectly axial. For applications requiring the load to be physically held in place during a pressure loss or valve centering, note that the standard adjustable air cushions only decelerate the piston near end-of-stroke and do not act as a brake. For positive holding, specify the SAIL variant with an air-released lock or an external pilot-operated check valve. This unit is dimensionally interchangeable per ISO 15552, meaning it serves as a direct replacement for other ISO 15552 profile cylinders when matching the 40mm bore, 230mm stroke, PT port, and standard mounting accessories (like FA/FB flanges).
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 SAI40BX230S FAQ
At a standard operating pressure of 0.5 MPa, this 40mm bore cylinder generates 628N of push force and 528N of pull force. At 0.7 MPa, the push force increases to 879N.
Yes, the SAI series is a genuine ISO 15552 profile cylinder. It is dimensionally interchangeable with other ISO 15552 cylinders of the same 40mm bore and 230mm stroke, matching standard mounting interfaces and PT port locations.
