The AirTAC SAIJ80 Adjustable Cylinder SAIJ80BX155-100 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø80mm bore and 155mm stroke, G3/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.
The AirTAC SAIJ80X155-100 is a double-acting, double-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 155 mm stroke that can be dialed back by up to 100 mm, yielding a highly flexible 55-155 mm usable travel window for precise end-position tuning at commissioning.
This specific SKU features a SUS304 stainless steel rod (option B) for superior corrosion resistance in harsh environments. It uses PT tapered port threads and lacks a magnet, meaning position sensing via CMSE or DMSE switches is not supported without modification. The extruded aluminum barrel includes sensor grooves on both sides, and the mounting set is limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 exact retract position between 55 and 155 mm during machine commissioning without replacing the cylinder or bolting on external stops.
Quickly adapt automated lines to new package dimensions by rotating the rear adjuster screw to shift the end-of-stroke position on the fly.
Leverage the SUS304 stainless steel rod for pushing and clamping tasks in washdown or chemical-heavy manufacturing areas requiring high force.
Choose this 80 mm bore cylinder when your application requires significant force—stepping down to a 63 mm bore yields 1559 N at 0.5 MPa, while stepping up to a 100 mm bore provides 3927 N. The 100 mm adjustment range is ideal for machines that process varying product sizes, allowing you to fine-tune the retract end-stop without swapping hardware or adding external stops.
For load-holding applications without live air pressure, note that the rear adjuster acts only as a travel stop, not a lock; consider the SAIL or BSAI series instead. Because the stroke is 155 mm, side-load risks are moderate, but for longer unsupported strokes, an external guide is recommended. Ensure your setup matches the PT port threads and the reduced SAIJ mounting interface.
Quick checklist
At 0.9 MPa, the push force increases to 4523 N.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective travel from the nominal 155 mm down to as little as 55 mm, giving a 55-155 mm usable window. It only sets the travel end and does not hold the load without live air pressure.
