The AirTAC SAI32 Standard Cylinder SAI32BX400S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 400mm 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 SAI32X400-S is a double-acting ISO 15552 profile cylinder engineered for precise linear motion. Delivering a push force of 402 N at 0.5 MPa, this 32 mm bore unit is tailored for applications requiring a 400 mm extension. The extruded aluminum barrel design omits tie rods, providing a clean exterior and standardized mounting interfaces.
This specific configuration includes a SUS304 stainless steel rod for superior corrosion resistance and a built-in magnet for position sensing. The dual sensor grooves on the barrel accept CMSE or DMSE switches, ensuring reliable feedback in automated 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.
Actuates diverter arms on packaging lines with its 400 mm reach, using the integrated magnet for end-of-stroke confirmation.
Provides consistent 402 N push force at 0.5 MPa for seating lightweight components in automated assembly fixtures.
Ejects machined small parts from a workstation, leveraging the SUS304 rod to withstand occasional moisture exposure.
Selecting this 32 mm bore over a larger 40 mm option (which provides 628 N at 0.5 MPa) is ideal when your application requires moderate force and a compact footprint. For a 400 mm stroke, the extended rod is susceptible to bending under side loads; utilizing an external guide rail or a guided cylinder mechanism is strongly recommended to prevent premature rod-bearing wear.
This model features PT tapered port threads and is dimensionally interchangeable per ISO 15552, serving as a direct replacement for other standard profile cylinders. If the machinery requires positive load holding during a pressure loss, pair this cylinder with an external pilot-operated check valve or transition to the SAIL locking variant.
Quick checklist
At 0.5 MPa operating pressure, this cylinder provides a push force of 402 N and a pull force of 345 N. At 0.7 MPa, the push force increases to 563 N.
Yes, the SAI32X400-S is dimensionally interchangeable per ISO 15552. It serves as a direct replacement for other standard profile cylinders with matching bore and stroke dimensions, utilizing standard mounting accessories.
