The AirTAC SAIJ80 Adjustable Cylinder SAIJ80AX190-50S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø80mm bore and 190mm 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 SAIJ80X190-50-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 140-190 mm usable travel window.
This variant includes a SUS420J2 stainless steel rod for improved corrosion resistance and a -S magnet for position sensing. It uses PT tapered ports and retains the standard extruded aluminum barrel with dual sensor grooves, supporting AirTAC CMSE reed and DMSE electronic switches.

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.

Quickly reconfigure the 140-190 mm travel window on packaging lines without changing the cylinder, minimizing downtime when switching package sizes.
Fine-tune the retract stop during machine commissioning to achieve precise mechanical alignment without adding external stops.
Ideal for assembly stations requiring flexible positioning limits, using the rear screw to set the exact 2513 N retraction endpoint.
The 50 mm adjustment range is ideal for machines requiring frequent product-size changeovers, replacing the need to swap out fixed-stroke SAI cylinders. For load-holding without live air pressure, select a SAIL or BSAI cylinder instead, as the rear adjuster here acts only as a travel stop.
As an ISO 15552 replacement, verify the 80 mm bore, 190 mm nominal stroke, PT port threads, and -S magnet. Because the stroke is under 300 mm, side-load stress is manageable, but always ensure the M20x1.5 rod thread is properly aligned with your external guide to prevent binding.
Quick checklist
At 0.7 MPa, the push force increases to 3518 N.
The rear adjuster allows you to shorten the 190 mm nominal stroke by up to 50 mm, creating a 140-190 mm usable travel window. It functions as a mechanical stop and does not lock the load without live air.
