The AirTAC SAIJ160 Adjustable Cylinder SAIJ160BX210-20S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø160mm bore and 210mm 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 SAIJ160X210-20-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 210 mm stroke by up to 20 mm. This yields a precise 190-210 mm usable travel window for commissioning without adding external stops. In the 160 mm bore class, it delivers substantial thrust, pushing 14074 N and pulling 9425 N at 0.7 MPa.
This configuration features a SUS304 stainless steel rod for corrosion resistance and includes a magnet for position sensing. The extruded aluminum barrel integrates sensor grooves on both sides, supporting AirTAC CMSE reed and DMSE electronic switches. The rear adjuster acts purely as a travel stop to decelerate the end-of-stroke position, so it 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 190-210 mm end-stop during machine commissioning to accommodate material thickness variations without swapping tooling.
Adjust the retract position on the fly to handle different package sizes on a heavy-duty handling line, utilizing the 20 mm travel window.
Select this adjustable-stroke model when an application requires exact end-position tuning during setup or product changeover, avoiding the need to swap out a fixed-stroke SAI cylinder.
To replace this cylinder on an ISO 15552 footprint, match the 160 mm bore, 210 mm stroke, 20 mm adjustment range, PT tapered port thread, and the -S magnet option. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the stroke is 210 mm, ensure adequate external guiding to manage side loads over the travel distance.
Quick checklist
The rear adjuster screw lets you shorten the effective travel from the nominal 210 mm down to 190 mm, creating a 190-210 mm usable window. This stopper only sets the end position and decelerates the travel; it does not lock or hold the load without live air pressure.
