The AirTAC SAI40 Standard Air Cylinder SAI40AX375 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø40mm bore and 375mm 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 SAI40X375 is a double-acting ISO 15552 profile cylinder engineered for standardized machine integration. It provides 628 N of push force at 0.5 MPa and 879 N at 0.7 MPa, making it well-suited for 375 mm travel mid-range actuation tasks.
This specific configuration features a SUS420J2 stainless steel piston rod (option A) for enhanced corrosion resistance in humid or mildly chemically washed environments. It utilizes PT tapered port threads and lacks a piston magnet, meaning position detection requires external proximity switches rather than internal reed or solid-state sensors.

Handles 375 mm linear travel to push cartons between adjacent conveyor lanes in packaging lines.
Advances blanks or sub-components into machining centers with reliable 628 N push force at 0.5 MPa.
Acts as a pneumatic stop gate for pallets accumulating at processing stations.
Selecting this 40 mm bore over the smaller 32 mm variant upgrades your 0.5 MPa push thrust from 402 N to 628 N, while stepping up to the 50 mm bore yields 982 N if higher clamping pressure is required. The 375 mm stroke is a standard length but requires careful mechanical planning.
Because the stroke is 375 mm, the extended rod is highly susceptible to bending under side loads. Always use an external guide rail or a fully guided cylinder to prevent premature rod-bearing wear. This standard SAI does not hold its load upon air loss; if the application requires dead-stop holding without live pressure, specify the SAIL (pneumatic lock) or BSAI (clamp-lock) variant. Being a true ISO 15552 profile barrel, it mounts dimensionally interchangeably with other ISO 15552 cylinders using FA/FB flanges or LB foot brackets.
Quick checklist
The cylinder generates 628 N of push force and 528 N of pull force at 0.5 MPa. At 0.7 MPa, the push force increases to 879 N.
Yes. As a genuine ISO 15552 profile cylinder, its mounting dimensions and PT G1/4 ports are fully interchangeable with other standard ISO 15552 cylinders of the same bore size.
