The AirTAC SAIJ200 Adjustable Cylinder SAIJ200X250-100S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 250mm stroke, G3/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.
The AirTAC SAIJ200X250-100-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. This built-in adjustability eliminates the need to swap cylinders or bolt on external stops during machine commissioning or product changeovers.
As an extruded aluminum profile cylinder, it integrates sensor grooves on both sides compatible with CMSE reed and DMSE electronic switches. The 40mm carbon steel rod and M36x2 thread provide high structural rigidity, while the rear adjuster functions strictly as a travel stop to set deceleration limits, not as a lock to hold loads without live air pressure.

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 exact bottoming position of a heavy forming or press operation within the 150-250mm window without changing out the entire cylinder.
Rapidly adapt automated machinery for different product lengths by dialing the rear stopper back up to 100mm during production line changeovers.
The 100mm adjustment range is ideal for machinery requiring variable end-stops across different product sizes, whereas a fixed-stroke SAI cylinder is better suited for dedicated, single-task stations. For operations needing true load-holding without continuous air pressure, consider the SAIL or BSAI series instead of relying on this stopper.
When replacing an ISO 15552 cylinder, match the 200mm bore, 250mm nominal stroke, 100mm adjuster, PT tapered port thread, and the -S magnet option. Because the 250mm stroke is relatively short for this massive bore, side-load concerns are manageable, but an external guide is still recommended for heavy offset loads. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.
Quick checklist
At the maximum rated pressure of 1.0 MPa, it can deliver up to 3204 kgf.
The rear adjuster screw allows you to shorten the effective travel from the 250mm nominal stroke by up to 100mm, creating a usable travel window of 150-250mm. This stopper sets the end position and deceleration point but does not lock or hold the load without live air pressure.
