The AirTAC Airtac SAI40 Standard Air Cylinder SAI40X380 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø40mm bore and 380mm 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 SAI40X380 is a double-acting ISO 15552 profile cylinder featuring a 40mm bore and a 380mm stroke. It generates 879N of push force at 0.7 MPa, making it suitable for medium-duty handling tasks. The extruded aluminum barrel omits tie-rods, providing a clean exterior while maintaining strict dimensional interchangeability with other ISO 15552 cylinders.
This configuration utilizes a standard carbon steel piston rod and tapered PT G1/4 ports. Because it lacks a magnet, it does not support internal reed sensors; if proximity detection is required, an -S variant with dual-side sensor grooves for CMSE or DMSE switches would be necessary.

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.
Ideal for diverting medium-weight packages on a conveyor line where the 879N thrust at 0.7 MPa easily overcomes friction and the 380mm stroke provides ample reach.
Used to push machined parts into staging bins, utilizing the full 380mm travel distance to clear the machining area safely.
Drives a vertical lifting platform for light-gauge materials, where the double-acting action ensures positive control in both directions.
Providing 628N of push force at 0.5 MPa, this 40mm bore is an upgrade from the 32mm bore (402N) for applications needing extra thrust without stepping up to the larger 50mm bore (982N). The 380mm stroke falls within the 1200mm standard limit for this bore, but because it exceeds 300mm, side loads can cause severe bending stress on the rod bearing. Employing an external guide rail or a fully guided cylinder is strongly recommended to prevent premature seal wear.
As a standard pneumatic actuator, this cylinder relies on live air pressure to move and hold its position; it will drift if air is removed. It is dimensionally interchangeable with other ISO 15552 profile cylinders using the same 40mm bore, 380mm stroke, G1/4 port, and standard mounting accessories like FA flanges or TC trunnions.
Quick checklist
The SAI40X380 generates 628N of push force and 528N of pull force at 0.5 MPa. At 0.7 MPa, the push force increases to 879N.
Yes, the SAI40X380 is a profile cylinder built to ISO 15552 mounting dimensions, making it a drop-in replacement for any standard ISO 15552 40mm bore cylinder with matching stroke and G1/4 port.
