The AirTAC Adjustable Cylinder SAIJ32 SAIJ32AX120-75S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 120mm stroke, G1/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.
The AirTAC SAIJ32X120-75-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a nominal 120 mm stroke that can be dialed back by up to 75 mm, creating a 45-120 mm usable travel window for precise end-position tuning at commissioning. The extruded aluminum barrel includes sensor grooves on both sides, and this -S variant includes a magnet for CMSE reed and DMSE electronic switches.
This model uses a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and features PT tapered port threads (G1/8). The rear adjuster acts strictly as a travel stop to fine-tune the retract end without adding external stops; it is not a lock and will not hold a load without live air pressure. The mounting interface supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 brackets.

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 45-120 mm retract position during initial commissioning without machining external stop blocks or changing the cylinder.
Quickly adjust the end-stop to accommodate different product sizes on a packaging line, utilizing the 75 mm adjustment range.
The 75 mm adjustment range is ideal for machine setups requiring variable end-stops or product-size changeovers without swapping the cylinder. If your application requires holding a load without continuous air pressure, consider the SAIL or BSAI series instead, as the SAIJ adjuster only sets the travel end.
For ISO 15552 replacement matching, verify the 32 mm bore, 120 mm stroke, 75 mm adjustment range, PT port threads, and the -S magnet requirement. The 12 mm rod and M10x1.25 thread handle moderate side loads, but for this 120 mm stroke, ensure proper guiding if the load is heavy or off-center. Operating speed ranges from 30-800 mm/s.
Quick checklist
At the maximum 1.0 MPa pressure, it delivers up to 82 kgf.
The rear adjuster screw allows you to shorten the effective stroke by up to 75 mm from the 120 mm nominal length, providing a usable travel window of 45-120 mm. It acts as a mechanical stop and does not lock the load without live air pressure.
