The AirTAC Airtac SAI40 Standard Air Cylinder SAI40X230S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø40mm bore and 230mm stroke, G1/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.
The AirTAC SAI40X230-S is a double-acting ISO 15552 profile cylinder featuring a 40mm bore and 230mm stroke. It generates 628N of push force at 0.5 MPa, making it well-suited for mid-range linear actuation tasks. The extruded aluminum barrel design omits tie-rods, providing a clean exterior that drops directly into standard ISO 15552 mounting footprints.
This specific configuration includes a magnetic piston (-S) for position detection and uses a standard carbon steel piston rod. It supports CMSE and DMSE reed switches via sensor grooves machined into both sides of the barrel. For high-temperature environments up to +70 C, the standard TPU seals can be swapped for Viton (H) or NBR (N) alternatives.

Related SAI-family variants: SAID (double rod), SAIJ (adjustable stroke), SAIL (with lock), SAIF (with valve), BSAI (enclasp / clamp-lock), and SAI-S with built-in magnet. Rod material: carbon steel (blank) / SUS420J2 (A) / SUS304 (B); seals: TPU (blank) / Viton H / NBR N.
Provides the 628N push force needed to divert parcels and boxes on automated distribution lines.
Holds workpieces securely in place during light machining or assembly operations using the 230mm stroke.
Actuates lifting gates and stops in automated storage and retrieval systems with reliable magnetic position feedback.
Selecting this 40mm bore over the smaller 32mm version increases your 0.5 MPa push thrust from 402N to 628N, while stepping up to a 50mm bore yields 982N. The 230mm stroke provides ample extension for packaging and sorting tasks. Because this stroke exceeds 300mm? No, at 230mm the side-load risk is moderate, but using external guides is still recommended if the load is heavy or off-center.
This cylinder uses a PT tapered G1/4 port and operates at speeds between 30-800 mm/s. If your application requires the load to stay fixed when air pressure is removed, a standard SAI will drift; you should specify the SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock instead.
Quick checklist
At an operating pressure of 0.5 MPa, this 40mm bore cylinder provides 628N of push force and 528N of pull force. At 0.7 MPa, the push force increases to 879N.
Yes, the SAI40X230-S is dimensionally interchangeable per ISO 15552. You can drop it into existing mounts matching the standard 40mm bore interface, but ensure your port and rod thread dimensions align.
