The AirTAC SAI40 Standard Air Cylinder SAI40BX230 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 interchangeable with other ISO 15552 cylinders at the mounting interface.
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.

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 528 N pull force needed to actuate routing gates on high-speed packaging lines over a 230 mm travel distance.
Ideal for holding aluminum or composite workpieces during light CNC machining, utilizing its 879 N push force at 0.7 MPa.
Raises lightweight tote boxes in storage retrieval systems, where the SUS304 rod prevents corrosion in fluctuating warehouse humidity.
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
At 0.7 MPa, the SAI40X230 generates 879 N of push force and 724 N of pull force. At a lower 0.5 MPa, it provides 628 N push and 528 N pull.
Yes, the SAI40X230 is an extruded aluminum profile cylinder with standardized ISO 15552 mounting dimensions, making it dimensionally interchangeable with other ISO 15552 cylinders of the same bore and stroke.
