The AirTAC SAIJ80 Adjustable Cylinder SAIJ80AX450-10 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø80mm bore and 450mm 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 SAIJ80X450-10 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster.
This variant uses an SUS420J2 stainless steel rod for improved corrosion resistance and features PT tapered port threads with a G3/8 connection. Because the stroke extends to 450mm, the 25mm rod diameter should be paired with an external guide to prevent excessive side-loading on the extruded aluminum barrel.

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.

Related SAI-family variants: SAID (double rod), SAIJ (adjustable stroke), SAIL (with lock), SAIF (with valve), BSAI (enclasp / clamp-lock), and SAI-S with built-in magnet. Rod material: carbon steel (blank) / SUS420J2 (A) / SUS304 (B); seals: TPU (blank) / Viton H / NBR N.
Fine-tune the 440 to 450mm retract position during initial commissioning to achieve precise end-stop alignment without machining new spacer blocks.
Quickly adjust the stroke end by up to 10mm on packaging lines when switching between slightly different product dimensions.
The 10mm adjustment range is ideal for fine-tuning end stops during machine setup or product changeovers, replacing the need to physically swap out a fixed-stroke SAI cylinder.
When integrating this model, remember the rear adjuster acts only as a travel stop and does not hold the load without continuous air pressure. For true load-holding requirements, consider an AirTAC SAIL or BSAI cylinder. As a dimensionally interchangeable ISO 15552 component, it shares the standard mounting footprint but utilizes a reduced SAIJ bracket set: Basic, FA, LB, TC, FTC, TCM1, and TCM2.
Quick checklist
At its maximum 1.0 MPa pressure, it can deliver up to 513 kgf.
The rear adjuster acts as a mechanical stop that lets you shorten the nominal 450mm stroke by up to 10mm, creating a 440 to 450mm travel window. It only sets the end position and does not lock the load without live air pressure.
