The AirTAC SAIJ80 Adjustable Cylinder SAIJ80AX475-10S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø80mm bore and 475mm 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 SAIJ80X475-10-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. This model includes a SUS420J2 stainless steel rod and a built-in magnet for position sensing.
Because the 475 mm stroke is relatively long, the 25 mm rod diameter and M20x1.5 thread provide necessary rigidity, though an external guide is recommended to manage side loads. The extruded aluminum barrel incorporates sensor grooves on both sides for CMSE reed or DMSE electronic switches. You can fine-tune the retract end position without swapping hardware or adding external stops.

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.

Fine-tune the 465-475 mm travel window during initial commissioning to perfectly dial in the retract end position without machining custom spacers.
Quickly adjust the stroke end-stop by up to 10 mm when a production line switches to a slightly different package or component size.
Choose this 80 mm bore when the 50 mm class (982N at 0.5 MPa) is insufficient but the 100 mm class (3927N at 0.5 MPa) is oversized. The adjustable 10 mm end-stop is ideal for product changeovers or fine-tuning machine setup, whereas a fixed SAI cylinder locks you into a single exact dimension. The PT tapered port threads (G3/8) and standard mounting interface ensure straightforward replacement.
For any stroke of 475 mm, you must account for side-load inertia; always use an external guide rail to prevent rod binding. Remember that the rear adjuster acts only as a travel stop, not a lock. If your application requires load-holding without live air pressure, select the SAIL pneumatic lock or BSAI clamp-lock cylinder instead. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.
Quick checklist
The rear adjusting screw acts as an external stopper that lets you mechanically shorten the effective stroke from 475 mm down to 465 mm. This allows precise end-position tuning at commissioning or during product changeovers without replacing the cylinder.
