The AirTAC SAIJ100 Adjustable Cylinder SAIJ100BX350-100S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø100mm bore and 350mm 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 SAIJ100X350-100-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 250-350 mm usable travel window by trimming up to 100 mm off the 350 mm nominal stroke.
This variant uses a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for CMSE reed and DMSE electronic sensors. The extruded aluminum barrel integrates sensor grooves on both sides, and the rear stopper allows rapid end-position tuning during commissioning without 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 exact end-stops on the fly when switching product sizes on a packaging line, utilizing the 100 mm travel window.
Fine-tune the retract position during commissioning without adding external physical stops or changing the cylinder.
The 100 mm adjustment window is ideal for product-size changeovers on a production line. Because the stroke is 350 mm, use an external guide to prevent rod sag and excessive side loading.
For ISO 15552 replacement matching, specify: 100 mm bore, 350 mm stroke, 100 mm adjustment, PT tapered ports, and the -S magnet. Remember that the rear adjuster acts only as a travel stop; it does not hold the load without live air. For true load-holding, select a SAIL or BSAI cylinder.
Quick checklist
It operates at speeds between 30 and 800 mm/s.
The rear adjuster screw allows you to shorten the effective travel by up to 100 mm, creating a 250-350 mm usable window. It acts as a physical stop and does not lock the load without live air pressure.
