The AirTAC SAI32 Standard Cylinder SAI32BX500 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 500mm 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 SAI32X500 is a double-acting ISO 15552 profile cylinder engineered for long-stroke automation tasks. It delivers a push force of 402 N at 0.5 MPa, utilizing a 500 mm extension to move loads efficiently across extended workspaces. As a tie-rod-less extruded aluminum design, it provides a clean, standardized mounting interface that drops directly into existing ISO 15552 setups.
This specific configuration features a SUS304 stainless steel piston rod for superior corrosion resistance and a PT tapered port thread. Because it lacks a magnet, external position sensing relies on standalone switches rather than the integrated barrel grooves. For environments requiring high-temperature durability, the standard TPU seals can be swapped for Viton (H) alternatives.

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 lightweight packages or parts across a 500 mm gap on a packaging line with 402 N of force at 0.5 MPa.
Extends fully to eject finished components from a machine bed, utilizing the SUS304 rod to resist minor moisture exposure.
Actuates low-profile stops or pushers at the end of roller conveyors where a 500 mm stroke is required to clear the pathway.
Selecting this 32 mm bore makes sense when your application requires moderate force over a long 500 mm distance. If you need less extension or higher cyclic speed, stepping down to a shorter stroke is ideal; conversely, if your load exceeds 402 N at 0.5 MPa, upgrading to the 40 mm bore (which provides 628 N) is recommended. This model utilizes PT tapered ports and supports standard ISO 15552 mounting accessories like LB foot brackets or FA flanges.
Because the 500 mm stroke creates an extended unsupported rod, side loads can cause bending stress on the rod bearing. To mitigate this, implement an external guide rail or choose a fully guided cylinder to prevent premature wear. Note that a standard SAI cylinder will drift if air pressure is lost; for applications requiring strict position holding without live pressure, consider the SAIL locking variant or an external pilot-operated check valve.
Quick checklist
At a 0.5 MPa operating pressure, this 32 mm bore cylinder provides a push force of 402 N and a pull force of 345 N. If you increase the pressure to 0.7 MPa, the push force rises to 563 N.
Yes, the SAI32X500 is dimensionally interchangeable per ISO 15552. You can drop it in as a replacement for other ISO 15552 profile cylinders by matching the 32 mm bore, 500 mm stroke, and your chosen mounting accessories.
