The AirTAC SAIJ100 Adjustable Cylinder SAIJ100AX210-20S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø100mm bore and 210mm 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 SAIJ100X210-20-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. The extruded aluminum barrel includes sensor grooves on both sides, and this -S variant includes a magnet for position detection.
This model features a SUS420J2 stainless steel rod (material code A) for improved corrosion resistance and uses PT tapered port threads (G1/2). The rear adjustment screw acts purely as a mechanical stop to set the travel end, meaning it does not lock or hold the load without continuous live air pressure. For load-holding requirements, an external pilot-operated check valve or a related SAIL lock cylinder is required.

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.

Fine-tune the 190-210mm retract position during machine commissioning to achieve exact material placement without adding external stopper blocks.
Quickly adjust the stroke by up to 20mm to accommodate different package sizes on a packaging line, minimizing downtime between production runs.
The adjustable 190-210mm window is ideal for product changeovers on a packaging line, replacing fixed-stroke SAI cylinders when you need variable end-stops. To match this ISO 15552 footprint exactly, specify the 100mm bore, 210mm stroke, 20mm adjustment, PT G1/2 port, and the -S magnet. Since the stroke exceeds 300mm on larger variants, always ensure external guiding for side loads, though this 210mm stroke is well within standard limits.
Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2. The integrated magnet works seamlessly with AirTAC CMSE reed switches and DMSE solid-state electronic sensors.
Quick checklist
At 0.7MPa, the push force increases to 5497N.
The rear adjuster screw allows you to shorten the nominal 210mm stroke by up to 20mm, creating a 190-210mm usable travel window. It functions as a mechanical stop and requires live air to hold position.
