The AirTAC SAIJ160 Adjustable Cylinder SAIJ160BX240-40 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 SAIJ160X240-40 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the effective travel to anywhere within a 200-240 mm window.
This specific configuration features a SUS304 stainless steel rod (material code B) for superior corrosion resistance and utilizes PT tapered port threads with a G3/4 connection. The rear adjuster acts purely as a mechanical stop to fine-tune the end position during commissioning; it does not lock the load, meaning live air pressure is required to hold position. For load-holding without continuous air, consider the SAIL or BSAI variants.

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.

Quickly shift the retract end-stop within the 200-240 mm window to accommodate different product sizes on the same production line without mechanical rebuilds.
Secures large workpieces with a 40 mm SUS304 stainless steel rod, providing the robust clamping force needed in automated fabrication cells.
Choose this 160 mm bore cylinder when an application requires substantial force—such as 14074 N at 0.7 MPa—that exceeds the output of a 125 mm bore (8590 N at 0.7 MPa). The 40 mm adjustment range is ideal for product changeovers on a line, allowing operators to shift the retract end-stop by up to 40 mm without swapping the cylinder or adding external stops. If your setup requires fixed travel without end-position tuning, a standard SAI cylinder is sufficient.
When replacing an ISO 15552 cylinder, match the 160 mm bore, 240 mm stroke, 40 mm adjustment, G3/4 PT ports, and the required mounting style. SAIJ supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, but omits FB, CA, CB, and CR. Because this unit lacks a magnet (-S), it cannot host CMSE or DMSE sensors without a configuration change. Note that while the 240 mm stroke is relatively short, the heavy 40 mm rod and M36x2 thread handle significant side loads, though external guides are always recommended for optimal longevity.
Quick checklist
At the maximum rated pressure of 0.9 MPa, the push force increases to 18095 N.
The rear mechanical stopper allows you to shorten the nominal 240 mm stroke by up to 40 mm, creating a usable travel window of 200 to 240 mm. This adjuster sets the end position but does not lock the load, requiring live air to maintain holding force.
