The AirTAC SAIJ100 Adjustable Cylinder SAIJ100BX800-30 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø100mm bore and 800mm 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.
It features a SUS304 stainless steel rod and PT tapered ports. By turning the rear screw, you achieve a 770-800mm usable travel window, perfect for dialing in exact end positions without swapping hardware.
This 100mm bore actuator omits the FB, CA, CB, and CR mounting styles, utilizing a focused set of ISO 15552 interfaces including Basic, FA, LB, TC, FTC, TCM1, and TCM2. The extruded aluminum barrel includes sensor grooves on both sides, though this specific SKU lacks a magnet for CMSE or DMSE switches.

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 770-800mm retract position during product family changeovers without disassembling tooling or adding external shims.
Dial in the exact end-of-stroke location for automated assembly presses requiring precise 3927N clamping at 0.5 MPa.
Actuate large diverter gates over an 800mm span, using the rear adjuster to synchronize stopping points across multiple lanes.
The 30mm adjustment window is ideal for product changeovers, allowing you to fine-tune the retract end-stop during commissioning rather than machining external stops. If your process requires holding a load without live air pressure, note that this rear adjuster acts only as a travel stop, not a lock; you should select an SAIL or BSAI cylinder instead.
Because the 800mm stroke is lengthy, the 25mm rod should be guided externally to prevent excessive side-loading and premature seal wear. To match this ISO 15552 cylinder exactly, specify the 100mm bore, 800mm stroke, 30mm adjustment, PT port thread, SUS304 rod material, and no magnet.
Quick checklist
At 0.7 MPa, the push force increases to 5497N.
The rear adjuster screw allows you to shorten the effective stroke by up to 30mm, creating a 770-800mm usable travel window. It acts as a mechanical stop to fine-tune the end position and does not lock the load without air pressure.
