The AirTAC SAI32 Standard Cylinder SAI32BX450S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 450mm stroke, G1/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.
The AirTAC SAI32X450-S is a double-acting ISO 15552 profile cylinder engineered for precise linear motion across a 450mm stroke. It generates 563N of push force at 0.7 MPa, making it well-suited for intermediate reach automation tasks. This configuration includes a magnet for position sensing.
Unlike standard carbon steel rods, this specific variant uses a SUS304 stainless steel rod (code B) to resist corrosion in humid or washdown environments. The barrel features dual sensor grooves compatible with CMSE and DMSE switches, while fluid connections use PT tapered threads.

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.
Pushes medium-weight cartons off a main conveyor line over a 450mm distance with reliable 402N force at 0.5 MPa.
Actuates sorting gates and routing arms where the SUS304 rod provides excellent durability against ambient humidity.
Moves workpieces between machining stations, utilizing CMSE sensors to confirm full extension at 450mm.
Selecting this 32mm bore over the smaller 40mm option (which provides 879N at 0.7 MPa) is ideal when footprint constraints matter more than raw thrust. For a 450mm stroke, the extended rod is highly susceptible to bending under side loads; utilizing external guide rails or a guided cylinder carriage is strongly recommended to prevent premature rod-bearing wear.
As a dimensionally interchangeable ISO 15552 profile cylinder, it serves as a direct replacement matching the 32mm bore, 450mm stroke, PT port, and standard mounting accessory dimensions. Note that the adjustable air cushions only decelerate the piston near stroke ends; if your process requires position holding without live air pressure, specify the SAIL lock or BSAI clamp-lock variant instead.
Quick checklist
At an operating pressure of 0.7 MPa, this 32mm bore cylinder provides a push force of 563N and a pull force of 345N. The maximum theoretical force at 1.0 MPa is 82 kgf.
Yes, the SAI32X450-S is a true ISO 15552 profile cylinder, making it dimensionally interchangeable with other ISO 15552 cylinders of the same bore and stroke. You can reuse existing FA flange or LB foot mounting brackets and PT port connections.
