The AirTAC SAIJ80 Adjustable Cylinder SAIJ80AX325-10 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø80mm bore and 325mm 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 SAIJ80X325-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel within a 315-325 mm window. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement.
This configuration uses a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and features PT tapered port threads with a G3/8 connection. Because the nominal stroke of 325 mm is relatively long, the 25 mm rod diameter provides robust support, though an external guide is recommended to manage side loads on unsupported lengths.

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 315-325 mm end position during commissioning to achieve precise tooling alignment without machining custom spacer blocks.
Quickly adjust the stroke end-stop by up to 10 mm on packaging lines when transitioning between slightly different product sizes.
The 10 mm rear adjuster is ideal for precision machine setup and product changeover, allowing you to dial in the exact end-of-stroke position without swapping out the entire cylinder or fabricating external mechanical stops.
For ISO 15552 replacement matching, ensure the new unit shares the 80 mm bore, 325 mm stroke, 10 mm adjustment range, G3/8 PT port, and the desired mounting style from the SAIJ subset: Basic, FA, LB, TC, FTC, TCM1, or TCM2. Note that the rear adjuster functions strictly as a travel stop and does not hold the load without live air; for positive load-holding, consider an AirTAC SAIL or BSAI cylinder.
Quick checklist
At the maximum 1.0 MPa pressure, it can deliver up to 513 kgf.
The rear adjusting screw acts as a mechanical stop, allowing you to shorten the effective travel from the 325 mm nominal stroke down to 315 mm. It only sets the travel end point and does not lock the load without continuous air pressure.
