The AirTAC SAIJ100 Adjustable Cylinder SAIJ100BX80-40S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø100mm bore and 80mm 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 SAIJ100X80-40-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 40 to 80 mm, letting you dial back the nominal 80 mm stroke by up to 40 mm during commissioning.
This specific SKU is configured with a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for CMSE reed and DMSE electronic sensors. The extruded aluminum barrel includes sensor grooves on both sides, and the mounting options cover 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 retract position within a 40 to 80 mm window during machine commissioning without swapping out the entire cylinder.
Quickly adapt the cylinder stroke on packaging lines handling varying product sizes by adjusting the rear stopper screw.
Leverage the SUS304 stainless steel rod for reliable actuation in washdown or mildly corrosive manufacturing environments.
If your process needs less force, stepping down to an 80 mm bore yields 2513 N at 0.5 MPa. The rear adjuster screw acts purely as a travel stop to fine-tune the retract position without adding external stops, but it does not hold the load without live air; for fail-safe load holding, consider an SAIL or BSAI cylinder.
To match this exact configuration for an ISO 15552 replacement, verify the 100 mm bore, 80 mm nominal stroke, 40 mm adjustment range, PT tapered port threads, and the -S magnet option. Operating speed spans 30 to 800 mm/s, making it highly responsive for dynamic cycles.
Quick checklist
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective stroke from 80 mm down to 40 mm. This creates a 40 to 80 mm usable travel window for fine-tuning end positions without replacing the cylinder.
