The AirTAC SAIJ80 Adjustable Cylinder SAIJ80BX600-30S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø80mm bore and 600mm 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 SAIJ80X600-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that trims the effective travel back by up to 30 mm. This creates a usable 570-600 mm stroke window, letting you dial in the exact end position during commissioning without swapping hardware.
Equipped with a SUS304 stainless steel rod and a magnet for position sensing, this unit accepts AirTAC CMSE reed and DMSE electronic switches. The extruded aluminum barrel includes sensor grooves on both sides, and the rear stopper simply sets the travel end. It does not lock the load without live air; use a SAIL or BSAI cylinder for pneumatic load-holding.

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 570-600 mm travel end-stop to handle different product sizes on the same line without changing cylinders.
Dial in the exact retract position during commissioning to meet tight tolerances without adding external mechanical stops.
Adjust the retract distance on the fly to accommodate varying package lengths moving down a material handling belt.
Choose this adjustable model over a fixed SAI when your setup requires fine end-tuning or frequent product-size changeovers. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets.
Because the 600 mm stroke is long, the unsupported load increases lateral stress on the 25 mm rod and M20x1.5 thread. You must use an external guide to prevent side-load damage. For a true ISO 15552 replacement, match the 80 mm bore, 600 mm stroke, 30 mm adjuster, PT tapered ports, and the -S magnet requirement.
Quick checklist
The rear adjuster acts as a mechanical stop, allowing you to shorten the 600 mm nominal stroke by up to 30 mm. This provides a usable travel window of 570-600 mm. The adjuster only sets the end position; it does not hold the load without live air pressure.
