The AirTAC Airtac Adjustable Cylinder SAIJ32 SAIJ32AX650-40 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 650mm 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 SAIJ32X650-40 is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 610-650 mm usable travel window by allowing you to trim the 650 mm nominal stroke back by up to 40 mm.
This configuration features a SUS420J2 stainless steel rod (material code A) for improved corrosion resistance and PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. Because the stroke is 650 mm, an external guide is highly recommended to prevent excessive side-loading on the rod.

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 610 to 650 mm retraction point during machine commissioning to accommodate varying product lengths without changing hardware.
Quickly adjust the rear stopper by up to 40 mm on a packaging line to handle different package sizes, reducing downtime between production runs.
Use the 650 mm travel to move components across a workstation, relying on the fine-tune adjuster to seat parts gently without shock.
Choose this 32 mm bore cylinder when an application requires precise end-position tuning at commissioning without the need to physically swap cylinders or bolt on external stops. Conversely, if your fixture demands higher thrust, a 50 mm bore provides 982 N.
This model uses PT tapered ports and omits the -S magnet; adding -S enables CMSE reed and DMSE electronic solid-state sensors. The rear adjuster acts strictly as a travel stop and does not hold the load without live air—always use an external rod lock, pilot-operated check valve, or AirTAC SAIL/BSAI series for load-holding. It supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.
Quick checklist
At the maximum 1.0 MPa pressure, it achieves 82 kgf.
The rear adjuster screw allows you to shorten the effective stroke by up to 40 mm, creating a 610-650 mm travel window. It functions as a mechanical stop to fine-tune the end position and does not lock the load without continuous air pressure.
