The AirTAC SAIJ160 Adjustable Cylinder SAIJ160BX180-40S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø160mm bore and 180mm 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 SAIJ160X180-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to fine-tune the retract end-position by up to 40 mm. This yields a usable travel window of 140 to 180 mm, letting you dial in the exact end-stop at commissioning without adding external physical stops. It delivers a robust 10053 N pull force at 0.5 MPa and features a SUS304 stainless steel rod for superior corrosion resistance.
This unit includes a magnet for position sensing, working seamlessly with AirTAC CMSE reed and DMSE electronic sensors. It uses a PT tapered G3/4 port and omits heavy tie-rod construction in favor of an extruded aluminum barrel with dual sensor grooves. The rear adjuster acts purely as a travel stop to set deceleration, meaning it will 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 140 to 180 mm travel window during line changeovers to accommodate different product sizes without swapping out the entire cylinder.
Use the rear adjuster to set precise retract positions on heavy machinery, tuning the end-of-stroke on the fly without installing external mechanical stops.
Leverage the SUS304 stainless steel rod for high-force pushing and pulling tasks in environments where standard carbon steel rods would fail.
Selecting this 160 mm bore model is appropriate when your application requires high thrust, specifically a 10053 N pull force at 0.5 MPa, which is a notable step up from the 6136 N offered by the 125 mm bore. An adjustable stroke is chosen over a fixed SAI cylinder when you need variable end-stops for machine setup or product changeovers. For load-holding without continuous air pressure, this cylinder is insufficient as the adjuster is not a brake; you should look at the SAIL or BSAI series instead.
Because the 180 mm stroke is under the 300 mm threshold, side-load risks are moderate, but the substantial 40 mm rod and M36x2 thread handle higher off-center loads well. When replacing an ISO 15552 cylinder, match the 160 mm bore, 180 mm nominal stroke, 40 mm adjustment range, G3/4 PT ports, and the -S magnet requirement. SAIJ supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets.
Quick checklist
The maximum force at 1.0 MPa is 2050 kgf.
The rear adjuster allows you to shorten the 180 mm nominal stroke by up to 40 mm, providing a usable travel window of 140 to 180 mm. It functions as a travel stop to tune the end position and does not lock the load without live air pressure.
