The AirTAC SAI32 Standard Cylinder SAI32BX425S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 425mm 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 SAI32X425-S is a double-acting ISO 15552 profile cylinder engineered for precise linear motion. It generates 402 N of push force at 0.5 MPa, making it suitable for medium-duty handling tasks. This 32 mm bore unit features a 425 mm stroke and includes a piston magnet for position sensing.
This specific configuration utilizes a SUS304 stainless steel rod (option B) for superior corrosion resistance. It is equipped with PT tapered port threads and integrates seamlessly with CMSE or DMSE sensor switches via the dual-side barrel grooves. As a genuine AirTAC component, it provides reliable direct interchangeability for any standard ISO 15552 mounting footprint.

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 cartons smoothly across sorting lanes with 402 N of thrust, utilizing the 425 mm stroke to clear adjacent conveyor belts.
Acts as a pneumatic stop for lightweight pallets in fulfillment zones, using the SUS304 rod to resist environmental moisture.
Ejects machined plastic parts from a molding area, relying on the dual-side sensor grooves and CMSE switches for exact timing.
Selecting this 32 mm bore model is ideal when your application requires the 402 N push force at 0.5 MPa, and stepping down is not an option. If your project demands higher thrust, consider moving up to the 40 mm bore, which provides 628 N at the same pressure. Because this unit features a 425 mm stroke, the extended rod is susceptible to bending under side loads; utilize an external guide rail or a guided cylinder module to prevent premature rod-bearing wear.
This cylinder uses adjustable air cushions at both ends to decelerate the piston smoothly, but it will not hold a load if air pressure is lost. For vertical applications requiring dead-load holding, integrate an external pilot-operated check valve or specify the SAIL lock variant. Replacement specifications include a 32 mm bore, 425 mm stroke, PT G1/8 ports, and the -S magnet option.
Quick checklist
At 0.5 MPa, this double-acting cylinder provides 402 N of push force and 345 N of pull force. If you increase the operating pressure to 0.7 MPa, the push force rises to 563 N.
Yes, the SAI32X425-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 mount it directly using standard FA, FB, or LB accessories.
