The AirTAC SAIJ100 Adjustable Cylinder SAIJ100BX375-10 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø100mm bore and 375mm 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 SAIJ100X375-10 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 365 to 375 mm usable travel window, allowing you to dial back the end position by up to 10 mm during commissioning without adding external stops.
This variant features a SUS304 stainless steel rod for corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes dual-side sensor grooves. Because the 375 mm stroke is relatively long, rely on an external guide to manage side loads rather than the M20x1.5 rod thread alone. The rear adjuster acts purely as a travel stop, so it will not hold a load 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.

Dial in the exact 365 to 375 mm travel window during setup to accommodate varying part heights in pressing operations without swapping hardware.
Quickly adjust the rear stopper by up to 10 mm to handle different package sizes on a packaging line during rapid format changes.
Choose this 100 mm bore when a 80 mm cylinder (2513 N at 0.5 MPa) lacks push force, or step down if you need less than 3927 N. An adjustable stroke is selected over a fixed SAI when a machine requires fine end-position tuning for product changeovers. For load-holding without continuous air, use a SAIL or BSAI cylinder instead, as the SAIJ rear stopper is not a lock.
To match this ISO 15552 cylinder, specify a 100 mm bore, 375 mm stroke, 10 mm adjustment, PT G1/2 ports, and your required mounting bracket from the SAIJ set: Basic, FA, LB, TC, FTC, TCM1, or TCM2. Note that FB, CA, CB, and CR mounts are omitted from this series. No magnet is specified for this unit, so CMSE or DMSE sensors cannot be used without modification.
Quick checklist
At 0.7 MPa, the push force increases to 5497 N.
The rear adjusting screw acts as a mechanical stop that lets you shorten the 375 mm nominal stroke by up to 10 mm, creating a 365 to 375 mm travel window. It only decelerates and sets the end position; it does not lock the load without live air.
