Airtac SAIJ80 Adjustable Cylinder SAIJ80AX180-40

Choose this 80 mm bore cylinder when your application requires substantial thrust—stepping down to a 50 mm bore drops the push force to 982 N at 0.5 MPa, while moving up to a 100 mm bore increases it to 3927 N. The 40 mm adjustment range is ideal for product-size changeovers on a line, allowing operators to reposition the retract endpoint quickly rather than sourcing and physically swapping a fixed-stroke SAI cylinder. For load-holding without continuous air pressure, this cylinder is insufficient; you must direct your setup to an external pilot-operated check valve, or select a SAIL pneumatic lock or BSAI clamp-lock variant instead.

When replacing an ISO 15552 cylinder, match these exact configuration parameters: 80 mm bore, 180 mm nominal stroke, 40 mm adjustment range, PT port thread, and no magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR. Because the 180 mm stroke is under the 300 mm threshold, side-load concerns are less critical than on longer strokes, but you should still ensure the 25 mm rod and M20x1.5 thread are aligned to prevent premature seal wear.
