The AirTAC SAIJ100 Adjustable Cylinder SAIJ100BX260-40S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø100mm bore and 260mm stroke, G1/2 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.
The AirTAC SAIJ100X260-40-S is a double-acting ISO 15552 profile cylinder with a rear stroke adjuster, letting you trim the nominal 260 mm travel back by up to 40 mm. This yields a precise 220-260 mm usable end-position window at commissioning without bolting on external stops.
This SKU features a SUS304 stainless steel rod for superior corrosion resistance and carries a built-in magnet for CMSE reed and DMSE electronic sensors. The extruded aluminum barrel includes sensor grooves on both sides, and the fluid porting uses a PT tapered G1/2 thread.

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 220-260 mm travel window during format changes without swapping the cylinder or repositioning hard stops.
Fine-tune the retract end-position at commissioning to absorb mechanical tolerances and achieve exact seating.
Set custom retract distances on automated lines where multiple product sizes require different stroke lengths.
Choose this adjustable-stroke model when a fixed SAI cylinder cannot accommodate product changeovers or fine end-position tuning on a 260 mm stroke. The rear screw acts purely as a travel stop to set deceleration, not as a lock; a plain SAIJ does not hold loads without live air, so for fail-safe holding point to the SAIL or BSAI series. Because the 260 mm stroke is substantial, always support the load with an external guide to prevent side-loading damage to the M20x1.5 rod thread.
For a direct ISO 15552 replacement, match the 100 mm bore, 260 mm stroke, 40 mm adjustment, PT G1/2 port, and the -S magnet. The mounting hardware uses the reduced SAIJ set: Basic, FA, LB, TC, FTC, TCM1, and TCM2.
Quick checklist
At 0.9 MPa, the push force increases to 7068 N.
The rear adjuster screw lets you shorten the 260 mm nominal stroke by up to 40 mm, creating a 220-260 mm usable travel window. It functions as a mechanical stop to set the end position, not as a load-holding lock.
