The AirTAC SAIJ80 Adjustable Cylinder SAIJ80BX290-10 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø80mm bore and 290mm 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 SAIJ80X290-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 280-290 mm usable travel window, allowing you to dial back the nominal 290 mm stroke by up to 10 mm during commissioning without adding external stops.
This variant uses a SUS304 stainless steel rod (option B) for corrosion resistance and features PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of CMSE reed or DMSE electronic sensors. The rear adjuster acts purely as a travel stop to set the retract end-position and does not hold the load without live air pressure.

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 280-290 mm retract end-position during initial commissioning to perfectly align packaging folds without external stopper hardware.
Quickly adjust the stroke by up to 10 mm on a packaging line when handling slightly different carton sizes, reducing downtime between production runs.
Fine-tune the final retract position on a heavy-duty assembly press, using the rear stopper to compensate for mechanical wear over time.
The 10 mm adjustment range is ideal for fine-tuning end positions during machine setup or product changeover, avoiding the need to swap out a fixed-stroke SAI cylinder. Because the 290 mm stroke is relatively long, an external guide is recommended to prevent excessive side-loading on the SUS304 rod.
For load-holding without continuous air pressure, this cylinder is insufficient as the rear adjuster and air cushions are not brakes; consider the SAIL (air-released lock) or BSAI (clamp-lock) series instead. This model is dimensionally interchangeable per ISO 15552 and uses a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2.
Quick checklist
The maximum thrust is 513 kgf at 1.0 MPa.
The rear adjuster screw lets you shorten the 290 mm nominal stroke by up to 10 mm, creating a 280-290 mm travel window. It acts as a mechanical stop to fine-tune the end position and is not a lock, meaning the cylinder requires live air to hold its load.
