The AirTAC SAIJ80 Adjustable Cylinder SAIJ80AX800-10 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø80mm bore and 800mm 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 SAIJ80X800-10 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 800 mm travel with a 10 mm external trim range, yielding a precise 790-800 mm usable window for fine-tuning the retract position without adding external stops.
This unit features a SUS420J2 stainless steel rod for enhanced corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, allowing you to mount CMSE reed or DMSE electronic switches directly. The rear adjuster acts purely as a travel stop to set deceleration, not as a lock, so live air is required to hold the load.

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 790-800 mm retract position precisely during product size changes without swapping out the entire cylinder.
Fine-tune the 10 mm adjustment window to set exact pressing depths at commissioning without external shims.
An adjustable stroke is selected over a fixed SAI model when you need to dial in the exact end position during machine commissioning or product changeovers. Because the rear screw is a stop and not a lock, use a SAIL or BSAI cylinder if the application requires load-holding without continuous air pressure.
For an exact ISO 15552 replacement, match the 80 mm bore, 800 mm stroke, 10 mm adjustment code, G3/8 PT ports, and your required mounting hardware. With an 800 mm stroke, the unsupported load increases lateral stress; always pair this cylinder with an external guide to prevent side-loading damage to the rod and seals. SAIJ supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, omitting FB, CA, CB, and CR.
Quick checklist
At 0.7 MPa, the push force increases to 3518 N.
The rear adjuster screw allows you to shorten the effective stroke by up to 10 mm, creating a 790-800 mm usable travel window. It functions as a mechanical stop to fine-tune the end position and does not lock the load without live air.
