The AirTAC Adjustable Cylinder SAIJ32 SAIJ32BX290-30 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 290mm 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 SAIJ32X290-30 is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 260-290 mm usable travel window, allowing you to dial back the nominal 290 mm stroke by up to 30 mm during commissioning.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. Note that the rear adjuster acts purely as a travel stop and does not hold the 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.

Quickly adjust the 260-290 mm travel window to accommodate different product lengths on a packaging line without changing out the physical cylinder.
Fine-tune the exact retract position during machine commissioning to align tools perfectly, using the rear screw rather than shimming.
An adjustable stroke is ideal for product-size changeovers on a line, letting you fine-tune the retract end position without swapping the cylinder or adding external stops. For fixed travel, a standard SAI cylinder is simpler.
When replacing an ISO 15552 cylinder, match the 32 mm bore, 290 mm stroke, PT ports, and mounting choice. SAIJ supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, omitting FB, CA, CB, and CR. Because the 290 mm stroke is relatively long for this bore size, ensure external guides support any side loads to protect the 12 mm rod. For load-holding without air, use a SAIL or BSAI cylinder instead.
Quick checklist
The rear adjuster screw lets you shorten the effective stroke by up to 30 mm, creating a 260-290 mm travel window. It functions as a mechanical stop to set the end position and does not lock the load without continuous air pressure.
