The AirTAC SAIJ100 Adjustable Cylinder SAIJ100BX850-10S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø100mm bore and 850mm 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 SAIJ100X850-10-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that lets you fine-tune the retract end position. It provides a usable travel window of 840-850 mm, allowing 10 mm of precise trimming without adding external stops.
This unit includes a magnet for CMSE reed and DMSE electronic sensors, fitting neatly into the extruded aluminum barrel grooves. It uses PT tapered ports and omits the FB, CA, CB, and CR mounts, offering the standard SAIJ set of Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 exact 840-850 mm retract position during commissioning to align heavy press tools without machining custom spacers.
Quickly adjust the end stop to accommodate slightly different package lengths on an automated packaging line.
The 10 mm rear adjuster is ideal for product changeovers, letting you dial in the end stop at commissioning rather than swapping a fixed-stroke SAI cylinder. Because the 850 mm stroke is long, always use an external guide to prevent excessive side loading on the M20x1.5 rod thread.
For an ISO 15552 replacement, match the 100 mm bore, 850 mm stroke, 10 mm adjustment, PT ports, and the -S magnet. Remember that the rear adjuster is a travel stop, not a lock; it will not hold the load without live air, so consider a SAIL or BSAI cylinder if true load-holding is required.
Quick checklist
The rear adjuster acts as a mechanical stop that allows you to shorten the effective stroke by up to 10 mm, providing a usable travel window of 840 to 850 mm. It sets the end position but does not lock the load without continuous air pressure.
