The AirTAC SAI80 Standard Air Cylinder SAI80BX145S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø80mm bore and 145mm stroke, G3/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.
The AirTAC SAI80X145-S is a double-acting ISO 15552 profile cylinder featuring a robust extruded aluminum barrel without external tie rods. Delivering a substantial 2513 N of push force at 0.5 MPa (3518 N at 0.7 MPa), this 80 mm bore unit is built for heavy-duty positioning tasks. The 145 mm stroke provides extended travel for packaging and material handling machinery.
This specific configuration includes a -S magnet for direct compatibility with CMSE and DMSE reed switches, utilizing the dual sensor grooves machined into both sides of the barrel. Furthermore, this model is equipped with a SUS304 stainless steel piston rod (material code B), ensuring maximum corrosion resistance and longevity in wash-down or high-moisture manufacturing environments.

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 2513 N push force at 0.5 MPa needed to drive forming crimpers and heavy sealing heads in continuous packaging lines.
Uses the 145 mm stroke to push heavy pallets onto secondary transfer conveyors, relying on the SUS304 rod for durability in dusty logistics hubs.
Delivers robust pulling force (2268 N at 0.5 MPa) to extract dense molded parts from tooling, utilizing the dual sensor grooves for end-of-stroke confirmation.
Choosing this 80 mm bore over the adjacent 63 mm version (which provides 1559 N push at 0.5 MPa) is necessary when your application requires moving heavier payloads or overcoming significant friction. If your process demands even higher thrust, stepping up to the 100 mm bore yields 3927 N at 0.5 MPa. This 145 mm stroke falls well within the 1500 mm standard maximum, keeping the rod bearing stress low without requiring external guides.
As a true ISO 15552 profile cylinder, the SAI80X145-S is dimensionally interchangeable with other ISO 15552 cylinders and serves as a direct replacement using standard mounting accessories like FA foot brackets or TC trunnion joints. The PT tapered ports are G3/8. Remember that the standard adjustable air cushions only decelerate the piston at stroke ends; they do not hold a load. If your system loses air pressure, the rod will drift. For fail-safe position holding, consider the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variants.
Quick checklist
At 0.5 MPa, it provides 2513 N of push force and 2268 N of pull force. At 0.7 MPa, the push force increases to 3518 N.
Yes, the SAI80X145-S is a genuine ISO 15552 profile cylinder, making it dimensionally interchangeable with older ISO 6431 or VDMA 24562 units of the same bore size.
