The AirTAC SAI32 Standard Cylinder SAI32BX425 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 is a double-acting ISO 15552 profile cylinder engineered to deliver 402 N of push force at 0.5 MPa. Its 425 mm stroke makes it well-suited for intermediate linear positioning tasks that require reliable, space-optimized actuation.
This specific configuration features a SUS304 stainless steel rod for superior corrosion resistance and utilizes PT tapered port threads. Because it lacks a built-in magnet, it operates without electronic position sensing, relying instead on its adjustable air cushions at both ends to decelerate the piston smoothly.

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 routing gates on packaging lines where a 425 mm stroke pushes intermediate totes to specific lanes.
Provides 402 N of push force at 0.5 MPa to seat small bearings or pins into housings without damaging components.
Ejects machined plastic parts from a mold cavity, utilizing the full 425 mm travel to clear the machine bed.
Selecting this 32 mm bore is ideal when your application requires around 402 N of thrust at 0.5 MPa but cannot accommodate the larger 628 N output of the 40 mm bore variant. At a 425 mm stroke, the unsupported rod length increases the risk of bending under side loads; utilizing an external guide rail or a guided cylinder module is strongly recommended to prevent premature rod-bearing wear.
As a dimensionally interchangeable ISO 15552 component, this model serves as a direct replacement matching the 32 mm bore, 425 mm stroke, PT port, and standard mounting accessory dimensions. Note that standard SAI cylinders do not hold loads when air pressure is lost; if your application requires pneumatic locking, consider the SAIL or BSAI variants.
Quick checklist
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. If you increase pressure to 0.7 MPa, the push force rises to 563 N.
Yes, the SAI32X425 is dimensionally interchangeable per ISO 15552. You can drop it in as a replacement for other 32 mm bore, 425 mm stroke ISO 15552 profile cylinders using identical mounting accessories.
