The AirTAC SAIJ100 Adjustable Cylinder SAIJ100BX55-10S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø100mm bore and 55mm 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 SAIJ100X55-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to fine-tune the end position during commissioning. With a nominal 55 mm stroke and a 10 mm adjustment range, it provides a usable travel window of 45 to 55 mm without requiring external stops.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet (-S) for position sensing. You can mount CMSE reed or DMSE electronic solid-state switches directly into the extruded aluminum barrel's dual sensor grooves. The mounting hardware covers Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, deliberately omitting FB, CA, CB, and CR configurations.

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.

Quickly dial in the 45-55 mm travel window during product family changeovers, using the rear stopper to set exact end positions without physically replacing the cylinder.
Utilize the integrated magnet with DMSE electronic sensors to confirm clamp engagement, while the SUS304 rod withstands harsh manufacturing environments.
Selecting this 100 mm bore cylinder makes sense when your application requires substantial thrust—up to 3927 N at 0.5 MPa—combined with exact end-position tuning. If your setup needs less force, stepping down to an 80 mm bore yields 2513 N at 0.5 MPa, whereas moving up to a 125 mm bore provides 6136 N. The adjustable stroke is ideal for product-size changeovers on a line, letting you dial in the 45-55 mm travel window rather than swapping to a fixed-stroke SAI cylinder.
Because the stroke is only 55 mm, side-loading is less of a concern than with longer strokes, but the robust 25 mm rod and M20x1.5 thread handle significant loads. Remember that the rear adjuster acts purely as a travel stop and the air cushion only manages deceleration; neither will hold a load without live air. For load-holding requirements without continuous pressure, consider an external pilot-operated check valve or the AirTAC SAIL lock cylinder. This unit is dimensionally interchangeable per ISO 15552.
Quick checklist
At 0.7 MPa, the push force increases to 5497 N.
The rear adjuster screw allows you to trim the effective travel back by up to 10 mm. This creates a usable stroke window of 45 to 55 mm, enabling fine end-position tuning at commissioning without adding external stops.
