The AirTAC SAIJ80 Adjustable Cylinder SAIJ80BX180-30S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø80mm bore and 180mm 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 SAIJ80X180-30-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. A PT tapered port thread ensures a tight, reliable pneumatic connection.
This variant includes a SUS304 stainless steel rod (code B) for superior corrosion resistance and is equipped with a magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel incorporates sensor grooves on both sides, and the adjustable stopper functions purely as a travel end-limit, not a load-holding lock.

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 150 to 180mm travel window on the fly to accommodate varying package dimensions without physically swapping cylinders on the line.
Use the 30mm rear stopper screw to precisely set the retract end-position during initial commissioning, avoiding the need for external shims.
The 30mm adjustment range is ideal for product size changeovers on a packaging line, allowing you to fine-tune the end position without swapping out the cylinder or adding external stops. For exact ISO 15552 replacement matching, verify the 180mm stroke, 30mm adjuster, PT G3/8 port, and the required -S magnet.
Because the stroke is 180mm, the M20x1.5 rod thread and 25mm rod diameter provide substantial rigidity, though any unsupported load should still use an external guide. Remember that the rear adjuster only sets the travel end; to hold a load securely without live air pressure, you must integrate an external rod lock or choose a SAIL or BSAI series cylinder.
Quick checklist
At a maximum 1.0 MPa, it can deliver up to 513 kgf.
The rear adjuster acts as a mechanical stop that allows you to shorten the effective stroke from its nominal 180mm down to 150mm. It only decelerates and sets the travel end; it does not lock or hold the load without continuous air pressure.
