The AirTAC SAIJ80 Adjustable Cylinder SAIJ80BX800-10S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø80mm bore and 800mm 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 SAIJ80X800-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 790 to 800 mm. The integrated magnet supports AirTAC CMSE reed and DMSE electronic sensors via the dual-side barrel grooves.
This model features a SUS304 stainless steel rod for corrosion resistance and uses PT tapered port threads. The rear adjuster acts purely as a travel stop to fine-tune the retract position without adding external physical stops. It is not a locking device; the cylinder relies on live air pressure to hold its load, so for true fail-safe load holding, consider SAIL or BSAI variants instead.

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 790-800 mm retract end-stop during initial commissioning of large equipment without installing secondary external physical stops.
Quickly adapt the stroke length on a packaging line when product dimensions change, using the rear screw to fine-tune the retraction point.
The 10 mm rear adjustment screw lets you dial in the exact retract end-stop during machine setup or product changeover without physically swapping the cylinder. To replace an ISO 15552 cylinder, match the 80 mm bore, 800 mm stroke, 10 mm adjustment, PT G3/8 ports, and the -S magnet requirement.
Because the 800 mm stroke is substantial, the 25 mm rod diameter and M20x1.5 rod thread provide robust support, but an external guide is strongly recommended to prevent excessive side-loading on the long unsupported piston rod. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR brackets.
Quick checklist
At the maximum 1.0 MPa pressure, the push force reaches 4523 N.
The rear adjusting screw acts as an external stopper that lets you shorten the effective stroke by up to 10 mm, creating a 790 to 800 mm usable travel window. It fine-tunes the retract end position but does not lock the load without live air pressure.
