The AirTAC SAIJ80 Adjustable Cylinder SAIJ80AX950-10 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø80mm bore and 950mm stroke, G3/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.
The AirTAC SAIJ80X950-10 is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear mechanical adjuster. This built-in adjuster allows precise end-position tuning during commissioning without adding external stops.
This specific configuration incorporates a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and uses PT tapered port threads with a G3/8 connection. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting, while the M20x1.5 rod thread handles substantial side loads effectively across the long 950mm stroke.

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 940-950mm travel window during product size changes without swapping out the entire actuator or repositioning hard stops.
Fine-tune the end-of-stroke position during initial commissioning to perfectly seat parts, relying on the built-in 10mm adjustment.
The adjustable stroke is ideal for machine setups requiring variable end-stops or product changeovers, offering more flexibility than a fixed-stroke SAI cylinder. Because the nominal stroke is 950mm, an external guide is strongly recommended to prevent excessive side-loading on the rod.
When specifying an ISO 15552 replacement, match the 80mm bore, 950mm stroke, 10mm adjustment range, PT G3/8 port, and the desired mounting style. The SAIJ series supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, but omits FB, CA, CB, and CR options. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air; for load-holding without pressure, consider an AirTAC SAIL or BSAI cylinder.
Quick checklist
At 0.7 MPa, the push force increases to 3518N.
The rear adjuster screw lets you shorten the 950mm nominal stroke by up to 10mm, creating a 940-950mm travel window. It functions purely as a mechanical stop to fine-tune the end position and does not lock the load.
