The AirTAC SAIJ100 Adjustable Cylinder SAIJ100BX650-10S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø100mm bore and 650mm stroke, G1/2 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.
The AirTAC SAIJ100X650-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 640-650mm usable travel window, allowing you to dial back the nominal 650mm stroke by up to 10mm during commissioning. The piston rod uses SUS304 stainless steel (code B) for superior corrosion resistance, and the -S magnet enables direct mounting of CMSE reed and DMSE electronic sensors along the dual-side extruded barrel grooves.
This adjustable-stroke design eliminates the need to swap cylinders or bolt on external stops when fine-tuning the retract end position. The rear screw acts purely as a travel stop to set the end-of-stroke deceleration point alongside the standard air cushions; it is not a lock and will not hold a load without live air pressure. For load-holding requirements without continuous air, consider the SAIL or BSAI series instead.

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 retract position within a 640-650mm window during product size changes without physically swapping the cylinder or adding external mechanical stops.
Utilize the SUS304 stainless steel piston rod for environments requiring high corrosion resistance, while relying on the -S magnet for electronic DMSE position sensing.
The adjustable 10mm window is highly beneficial for machine changeovers, allowing operators to trim the 650mm travel back to 640mm without replacing the actuator. Because the 650mm stroke is relatively long, the 25mm rod diameter and M20x1.5 rod thread provide robust support, but an external guide rail is strongly recommended to prevent excessive side-loading on the piston rod.
As a dimensionally interchangeable ISO 15552 profile cylinder, it replaces equivalent standard profile cylinders using a PT tapered port thread and a reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). It omits FB, CA, CB, and CR mounting styles. The integrated -S magnet works seamlessly with AirTAC CMSE and DMSE sensors for position feedback.
Quick checklist
At the maximum operating pressure of 1.0 MPa, it delivers up to 801 kgf.
The rear adjuster screw allows you to shorten the effective travel by up to 10mm, creating a 640-650mm usable stroke window. It functions as a mechanical stop to set the end position and does not lock or hold the load without continuous air pressure.
