The AirTAC SAIJ100 Adjustable Cylinder SAIJ100AX45-30S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø100mm bore and 45mm 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 SAIJ100X45-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. The integrated magnet allows for precise position detection using CMSE reed or DMSE electronic sensors.
This specific SKU provides a usable travel window of 15 to 45mm, enabling you to dial back the nominal 45mm stroke by up to 30mm during commissioning. It features a SUS420J2 stainless steel rod for corrosion resistance and uses a PT tapered port thread. The extruded aluminum barrel includes sensor grooves on both sides, and the mounting set covers 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 end position during product size transitions without physically replacing the cylinder or adding shims.
Fine-tune clamping travel on heavy fixtures where the exact contact point varies by a few millimeters.
Set precise retract distances for automated assembly stations that process varying component heights.
Choose this adjustable-stroke cylinder when your application requires fine end-position tuning at commissioning or frequent product-size changeovers without swapping out the entire cylinder or adding external stops. The 25mm rod and M20x1.5 thread handle high side loads well, but even with a robust rod, any long unsupported stroke requires an external guide. To match your system, note the 100mm bore, 45mm stroke, 30mm adjustment, PT G1/2 port, and -S magnet.
If you need to hold a load without live air pressure, note that the rear adjuster acts only as a travel stop, not a lock. For secure load-holding, consider the SAIL pneumatic lock, BSAI clamp-lock, or an external rod lock.
Quick checklist
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective stroke by up to 30mm. This gives the 45mm nominal stroke a usable travel window of 15 to 45mm, allowing fine-tuning at commissioning without external stops.
At the maximum 1.0MPa pressure, the push force reaches 801kgf.
