The AirTAC Adjustable Cylinder SAIJ32 SAIJ32BX190-30S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 190mm 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 SAIJ32X190-30-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It features a SUS304 stainless steel rod and a built-in magnet for position sensing. By turning the rear adjustment screw, you can shorten the nominal 190 mm stroke by up to 30 mm, creating a precise 160-190 mm usable travel window for fine-tuning end positions at commissioning without swapping the cylinder.
The extruded aluminum barrel includes sensor grooves on both sides, directly supporting AirTAC CMSE reed and DMSE electronic solid-state switches. The rear adjuster acts purely as a mechanical travel stop to set deceleration and end-points, meaning it will not hold a load without live air pressure.

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.

Dial in the 160-190 mm travel window during product size transitions to set new retract endpoints without replacing the cylinder or adding external stopper blocks.
Use the rear screw to fine-tune the exact clamping position during initial commissioning, absorbing minor mechanical tolerances in the fixture build.
Adjust the stroke on the fly for repetitive testing sequences, relying on the SUS304 rod for corrosion resistance in varied environmental conditions.
Choose this 32 mm bore adjustable-stroke cylinder when your application requires exact end-position tuning during machine setup or product changeovers, avoiding the need to bolt on external stops or buy multiple fixed-length SAI cylinders. Because the total stroke is 190 mm, the 12 mm rod and M10x1.25 thread provide adequate support, but an external guide is recommended for any heavy offset loads.
For a true ISO 15552 replacement, match the 32 mm bore, 190 mm stroke, 30 mm adjustment range, PT tapered port thread, and the -S magnet option. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2. Remember that the rear adjuster is a stop, not a lock; if you need fail-safe load holding without live air pressure, consider the AirTAC SAIL or BSAI series instead.
Quick checklist
The rear adjuster screw acts as a mechanical stop that can shorten the 190 mm nominal stroke by up to 30 mm, providing a usable travel window of 160-190 mm. It sets the end position but does not lock or hold the load without continuous air pressure.
