The AirTAC Airtac SAI40 Standard Air Cylinder SAI40BX700 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø40mm bore and 700mm 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 SAI40X700 is a double-acting ISO 15552 profile cylinder featuring a 40mm bore and a 700mm stroke. It generates 628N of push force and 528N of pull force at 0.5 MPa, making it well-suited for automated machinery requiring extended reach. The extruded aluminum barrel omits tie rods, providing a smooth exterior that simplifies cleaning and reduces debris accumulation.
This specific configuration utilizes a SUS304 stainless steel rod (material code B), offering superior corrosion resistance for humid or washdown environments. Because a magnet is not specified, the barrel's integrated sensor grooves remain available for future automation upgrades if needed.

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 or index heavy pallets along long conveyor lines without requiring intermediate actuators.
The 700mm stroke reaches across wide machine beds to transfer components between processing stations efficiently.
The SUS304 stainless steel rod excels in packaging machinery where frequent washdowns or high ambient humidity would degrade standard carbon steel rods.
Choose this 40mm bore when a 32mm cylinder (providing 402N push at 0.5 MPa) lacks the necessary thrust, but a 50mm bore (982N push at 0.5 MPa) would be overkill. The 700mm stroke falls within the standard maximum of 1200mm for this bore size. However, at this extended length, the unsupported rod is highly susceptible to bending under side loads. To prevent premature seal wear and rod-bearing failure, implement an external linear guide or select a guided cylinder module.
As a true ISO 15552 standardized cylinder, this model serves as a direct dimensional replacement for other ISO 15552 profile cylinders. It features a PT G1/4 port, an M12x1.25 rod thread, and adjustable air cushions at both ends. Note that standard double-acting cylinders do not hold loads safely upon air loss; for vertical applications requiring fail-safe holding, consider the SAIL locking variant or an external rod lock.
Quick checklist
At 0.5 MPa, the SAI40X700 provides 628N of push force and 528N of pull force. When operating at 0.7 MPa, the push force increases to 879N.
Yes. It is manufactured to the exact ISO 15552 profile standard, making it dimensionally interchangeable with other ISO 15552 cylinders of the same bore size, ensuring straightforward mounting and port replacement.
