The AirTAC Adjustable Cylinder SAIJ32 SAIJ32BX270-30S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 270mm 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 SAIJ32X270-30-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 270 mm stroke that can be fine-tuned down by up to 30 mm, giving you a precise 240-270 mm usable travel window.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for position sensing. You can dial in the retract end-position during commissioning without swapping hardware or adding external stops. The rear adjuster acts strictly as a travel stop, not a lock, so live air is required to hold the load.

Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Quickly dial in the 240-270 mm travel window during format size changes on a packaging line without replacing the cylinder.
Fine-tune the retract end position during initial commissioning to achieve precise alignment without machining external stops.
Adjust the stroke on the fly for diverter gates that need to accommodate different package sizes on a single conveyor.
Choose this 32 mm bore cylinder when an application requires exact end-position tuning alongside a 240-270 mm travel window. Conversely, if you only need a fixed end stop without adjustability, a standard SAI cylinder simplifies the setup.
For a direct ISO 15552 replacement, match the 32 mm bore, 270 mm stroke, PT tapered port threads, and the -S magnet option. Mounting choices are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the 270 mm stroke is relatively long for this compact bore, ensure external guides are used to prevent excessive side-loading on the rod.
Quick checklist
A rear adjusting screw acts as a mechanical stopper, allowing you to shorten the effective stroke by up to 30 mm. This creates a usable travel window of 240-270 mm. Note that this adjuster is a stop, not a lock; the cylinder requires live air to hold its position.
