The AirTAC SAIJ100 Adjustable Cylinder SAIJ100BX260-30S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø100mm bore and 260mm stroke, G1/2 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.
The AirTAC SAIJ100X260-30-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 260 mm nominal stroke that can be fine-tuned down by up to 30 mm, yielding a usable travel window of 230-260 mm for precise end-position calibration at commissioning.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel incorporates sensor grooves on both sides, and the rear stopper allows you to dial in the retract position without adding external stops or swapping the cylinder.

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 230-260 mm retract position during format size changes on a packaging line without replacing the cylinder or adding external hard stops.
Fine-tune the end-of-stroke position during initial commissioning to achieve precise mechanical alignment using the rear 30 mm adjusting screw.
The adjustable 230-260 mm window is ideal for product-size changeovers on a line, letting you tune the retract end-stop on the fly instead of machining new hard stops. Because the stroke is 260 mm, ensure an external guide supports the load to prevent excessive side loading on the M20x1.5 rod.
For an exact ISO 15552 replacement match, verify a 100 mm bore, 260 mm stroke, 30 mm adjustment, PT tapered ports, and the -S magnet. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding without pneumatic pressure, consider an AirTAC SAIL or BSAI cylinder. SAIJ supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.
Quick checklist
At 0.7 MPa, the push force increases to 5497 N.
The rear adjuster acts as a mechanical stop that lets you shorten the effective stroke by up to 30 mm. This creates a usable travel window of 230-260 mm from the 260 mm nominal stroke, allowing precise end-position tuning without changing the cylinder.
