The AirTAC SAIJ80 Adjustable Cylinder SAIJ80BX35-30 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø80mm bore and 35mm stroke, G3/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.
The AirTAC SAIJ80X35-30 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling precise end-position tuning without swapping hardware. With a nominal 35mm stroke and a 30mm adjustment range, the usable travel window spans 5 to 35mm, making it ideal for short-stroke applications requiring exact positioning.
This configuration includes a SUS304 stainless steel rod (option B) for superior corrosion resistance and a PT tapered port thread. The 25mm rod and M20x1.5 rod thread provide excellent side-load capability for the compact travel distance. Mounting options are restricted to the SAIJ subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.

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.

Related SAI-family variants: SAID (double rod), SAIJ (adjustable stroke), SAIL (with lock), SAIF (with valve), BSAI (enclasp / clamp-lock), and SAI-S with built-in magnet. Rod material: carbon steel (blank) / SUS420J2 (A) / SUS304 (B); seals: TPU (blank) / Viton H / NBR N.
Ideal for clamping or pressing tasks where the exact contact point varies, using the 5-35mm adjustable window to fine-tune the end position during machine setup.
Enables rapid adjustment on automated lines when switching between product sizes, dialing the stroke back up to 30mm without replacing the cylinder.
The SUS304 stainless steel rod excels in packaging or light-washdown environments where standard carbon steel rods might degrade over time.
Choose this 80mm bore when an application requires higher force than a 63mm cylinder (which provides 1402N pull at 0.5 MPa) but has tight spatial constraints. The adjustable stroke is perfect for machine setup and product changeover, allowing operators to dial in the exact 5-35mm travel window during commissioning rather than machining external stops. For fixed-length requirements without the need for field adjustments, the standard SAI cylinder is a simpler alternative.
When ordering, verify the 80mm bore, 35mm nominal stroke, 30mm adjustment range, PT port thread, and SUS304 rod material. Because the stroke is under 300mm, external side-load guides are less critical than on longer strokes, but the load should still be aligned to prevent binding. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air; for pneumatic locking without pressure, consider the SAIL or BSAI series.
Quick checklist
At the maximum 1.0 MPa pressure, it can deliver up to 513 kgf.
The rear adjuster screw allows you to shorten the effective stroke from the nominal 35mm down to as little as 5mm. This creates a 5-35mm usable travel window for fine-tuning the retract end position without adding external stops.
