The AirTAC SAIJ160 Adjustable Cylinder SAIJ160BX240-20S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø160mm bore and 240mm stroke, G3/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.
The AirTAC SAIJ160X240-20-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 220-240 mm usable travel window, letting you dial back the 240 mm nominal stroke by up to 20 mm during commissioning.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for CMSE and DMSE sensors. The extruded aluminum barrel includes sensor grooves on both sides. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for position holding without pressure, consider an external rod lock or the SAIL lock cylinder.

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 retract end-position by up to 20 mm during product-size changeovers without adding external stops or replacing the cylinder.
Dial in the exact 220-240 mm travel window required for delicate pressing or positioning tasks at commissioning.
The adjustable stroke is ideal for machine setups requiring variable end stops or product-size changeovers.
This model uses a PT tapered port and a G3/4 thread. It supports mounting options Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. Because the 240 mm stroke is under 300 mm, side-load concerns are less severe than with longer strokes, but an external guide is still recommended for heavy loads. To replace an ISO 15552 cylinder, match the 160 mm bore, 240 mm stroke, 20 mm adjustment, PT port, mounting, and the -S magnet.
Quick checklist
The rear adjuster screw lets you shorten the 240 mm nominal stroke by up to 20 mm, creating a 220-240 mm usable travel window. It functions as a mechanical stop to fine-tune the end position and does not lock the load without live air pressure.
