The AirTAC SAIJ100 Adjustable Cylinder SAIJ100AX170-30 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø100mm bore and 170mm 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 SAIJ100X170-30 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to fine-tune the end-of-travel position. It provides a usable travel window of 140 to 170 mm, letting you dial back the stroke by up to 30 mm during commissioning without bolting on external stops.
This unit features a SUS420J2 stainless steel piston rod (option A) for improved corrosion resistance and includes PT tapered port threads. The extruded aluminum barrel integrates sensor grooves on both sides, supporting AirTAC CMSE reed and DMSE electronic sensors if a magnet is added later. Mounting options cover the SAIJ subset: 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 140-170 mm end-stop during machine setup to accommodate different product lengths without swapping cylinders.
Fine-tune the retract position during commissioning to align heavy fixtures precisely using the rear adjusting screw.
Choose this 100 mm bore when your application requires substantial thrust—stepping up to the 125 mm bore yields 6136 N at 0.5 MPa, while dropping to the 80 mm bore provides 2513 N. The adjustable stroke is ideal for product changeovers on a line where the exact end-stop position varies slightly. For load-holding without live air pressure, note that the rear adjuster is a travel stop, not a lock; you would need an external rod lock or a SAIL cylinder instead.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 170 mm stroke, 30 mm adjustment range, G1/2 port, and the desired mounting bracket. The 170 mm stroke is well within the 1500 mm standard maximum, so no external side-load guide is strictly required for normal loads, though the M20x1.5 rod thread handles robust connections.
Quick checklist
At 0.7 MPa, the push force increases to 5497 N.
The rear adjuster acts as a travel stop, allowing you to shorten the 170 mm nominal stroke by up to 30 mm. This creates a usable travel window of 140 to 170 mm, which can be fine-tuned during commissioning without adding external stops.
