The AirTAC Airtac SAIJ80 Adjustable Cylinder SAIJ80AX90-75 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø80mm bore and 90mm stroke, G3/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.
The AirTAC SAIJ80X90-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel. With a nominal 90 mm stroke and a 75 mm adjustment range, it provides a highly versatile 15-90 mm usable travel window for precise end-position tuning during commissioning. It delivers a robust 2513 N push force at 0.5 MPa, making it ideal for heavier actuation tasks.
This model is configured with an SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and uses PT tapered port threads. It features variable air cushions at both ends to manage kinetic energy. The rear adjuster acts purely as a mechanical stop to set the retract position and does not hold the load without live air pressure; for fail-safe load holding, consider the SAIL or BSAI series.

Fine-tune the 15-90 mm travel window during machine setup to perfect positioning without adding external stops.
Leverage the 2513 N push force at 0.5 MPa for pressing or forming tasks that require variable depth control.
Choose this 80 mm bore cylinder when your application requires substantial force (2513 N push at 0.5 MPa) but demands on-the-fly stroke modifications without swapping out the barrel. The 75 mm adjustment range is exceptionally wide, allowing a single cylinder to cover varied product sizes on a changeover line. If your force requirements are lower, stepping down to a 63 mm bore yields 1559 N push force, while upgrading to a 100 mm bore provides 3927 N. Because the nominal stroke is under 300 mm, side-load stress on the 25 mm rod is moderate, though external guides are always recommended for offset loads.
When replacing an ISO 15552 cylinder, match the 80 mm bore, 90 mm stroke, PT G3/8 ports, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Note that FB, CA, CB, and CR mounts are omitted from this adjustable series. As no magnet is specified, this unit cannot host CMSE reed or DMSE electronic sensors without modification.
Quick checklist
A rear external screw acts as a mechanical stopper, allowing you to shorten the nominal 90 mm stroke by up to 75 mm. This creates a 15-90 mm adjustable travel window. The adjuster only sets the end position; it does not lock the load without live air pressure.
At a 0.5 MPa operating pressure, the SAIJ80X90-75 provides 2513 N of push force and 2268 N of pull force. At 0.7 MPa, the push force increases to 3518 N.
