The AirTAC SAIJ100 Adjustable Cylinder SAIJ100AX110-20 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø100mm bore and 110mm 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 SAIJ100X110-20 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the 110 mm nominal stroke by up to 20 mm. This yields a precise 90-110 mm usable travel window, enabling fine end-position tuning at commissioning without swapping out the physical cylinder or adding external stops.
This configuration features a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. While the rear screw acts as a travel stop to set deceleration, it does not hold the load without live air; for dead-load holding, consider the SAIL or BSAI series.

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 90-110 mm travel window during product size changes to set new extended positions without physically remounting the actuator.
Fine-tune the final extended position during commissioning using the rear adjuster, preventing hard mechanical crashes on heavy tooling.
The adjustable stroke is ideal for machine setup where the exact extended position needs micro-tuning on the fly, unlike a fixed-stroke SAI cylinder.
Because the 110 mm stroke is relatively short, side-loading is less of a concern than with longer strokes, but the 25 mm rod and M20x1.5 thread still handle robust loads. To match this ISO 15552 interchangeable cylinder exactly, specify the 100 mm bore, 110 mm stroke, 20 mm adjustment, PT port, and the SUS420J2 rod material. Note that the mounting set is limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2 options.
Quick checklist
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective stroke by up to 20 mm. This provides a usable travel window of 90 to 110 mm, allowing you to trim the end position without replacing the cylinder.
If higher pressure is used, the push force increases to 5497 N at 0.7 MPa.
