The AirTAC SAIJ80 Adjustable Cylinder SAIJ80BX80-30S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø80mm bore and 80mm 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 SAIJ80X80-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 50 to 80 mm.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for CMSE reed and DMSE electronic sensors. Fluid control utilizes PT tapered ports sized at G3/8, while the extruded aluminum barrel maintains standard ISO 15552 mounting dimensions without relying on tie-rod construction.

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 retract distance between 50 and 80 mm during machine commissioning to accommodate varying material thicknesses without adding external stops.
Quickly adjust the end-of-stroke position on packaging lines when switching between different package sizes, minimizing downtime and mechanical rework.
Select this 80 mm bore cylinder when an application requires exact end-stop calibration without swapping components during product changeovers. Because this is an 80 mm stroke, the 30 mm adjustment window is exceptionally broad, allowing significant mechanical retraction.
To match this exact configuration for an ISO 15552 replacement, specify an 80 mm bore, 80 mm stroke, 30 mm adjustment range, PT tapered ports, a SUS304 rod, and the -S magnet option. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding, consider an external rod lock or the AirTAC SAIL series. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.
Quick checklist
At the maximum 1.0 MPa pressure, it achieves a peak push force of 513 kgf.
The rear adjusting screw acts as a mechanical stop that shortens the nominal 80 mm stroke by up to 30 mm, creating a usable travel window of 50 to 80 mm. It decelerates the travel end but does not lock the load without continuous air pressure.
