The AirTAC Adjustable Cylinder SAIJ32 SAIJ32AX190-50 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 190mm stroke, G1/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.
The AirTAC SAIJ32X190-50 is a double-acting, double-rod ISO 15552 profile cylinder featuring a rear mechanical stroke adjuster. It provides a nominal 190 mm travel that can be dialed back by up to 50 mm, creating a 140-190 mm usable window for precise end-position tuning. The piston rod uses SUS420J2 stainless steel, and the barrel is an extruded aluminum profile with sensor grooves on both sides.
This adjustable design eliminates the need to swap cylinders or add external stops during product changeovers. The rear adjuster acts purely as a travel stop and does not lock or hold the load without live air pressure. It supports a speed range of 30-800 mm/s and uses PT tapered port threads with a G1/8 connection.

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 dial in the 140-190 mm stroke window during product size transitions without swapping cylinders or adding external stops.
Fine-tune the retract end position at commissioning to perfect part ejection or clamping accuracy on automated lines.
Set custom travel limits for short-run batches, using the rear adjuster to safely restrict the 190 mm nominal stroke.
The 50 mm adjustment range is ideal for machines running multiple product sizes, allowing rapid commissioning without replacing the cylinder. For load-holding requirements without continuous air pressure, use a SAIL or BSAI cylinder instead, as the SAIJ adjuster is only a stop.
When replacing an ISO 15552 cylinder, match the 32 mm bore, 190 mm stroke, 50 mm adjustment, PT G1/8 port, and SUS420J2 rod material. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2. Since this model lacks a -S magnet, it cannot host CMSE or DMSE sensors without modification.
Quick checklist
The rear adjuster allows you to shorten the effective stroke by up to 50 mm, creating a 140-190 mm usable travel window. It acts as a mechanical stop to fine-tune end positions and does not hold the load without live air pressure.
