The AirTAC SAIJ160 Adjustable Cylinder SAIJ160BX160-40 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø160mm bore and 160mm stroke, G3/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.
The AirTAC SAIJ160X160-40 is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers massive thrust, pushing 18095 N at 0.9 MPa, making it suited for heavy-duty positioning. By turning the external stopper screw, you can trim the effective travel back by up to 40 mm, creating a precise 120-160 mm usable stroke window without swapping out the unit.
This specific configuration features a SUS304 stainless steel rod for superior corrosion resistance and includes PT tapered ports. The extruded aluminum barrel incorporates sensor grooves on both sides for direct switch mounting. While the rear adjuster allows you to dial in the exact retract position during commissioning, it functions strictly as a travel stop and does not lock the load without continuous live air pressure.

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 120-160 mm retract position during format changes on a packaging line, using the rear screw to set new end stops without replacing the cylinder.
Trim up to 40 mm of travel during initial machine setup to perfectly align tooling, preventing mechanical interference without machining custom spacers.
Select this 160 mm bore cylinder when an application requires substantial force—such as the 14074 N generated at 0.7 MPa—that smaller bores cannot provide, stepping up from a 125 mm bore that yields 8590 N at the same pressure. The adjustable 120-160 mm window is ideal for machinery that undergoes frequent product changeovers, allowing operators to fine-tune the retract end position mechanically rather than adding external stops or reverting to a fixed-stroke SAI cylinder. If your setup requires holding a load securely without air pressure, a plain SAIJ will not suffice; you should explore the SAIL air-released lock or BSAI clamp-lock series instead.
Because this model features a 160 mm stroke, side-loading is less of a concern than on longer units, but the heavy 40 mm rod and M36x2 thread provide excellent rigidity for absorbing lateral stresses. For ISO 15552 replacement matching, verify the 160 mm bore, 160 mm stroke, 40 mm adjustment, PT port thread, and your required mounting bracket from the SAIJ subset (Basic, FA, LB, TC, FTC, TCM1, TCM2). Note that FB, CA, CB, and CR mounts are omitted from this adjustable series.
Quick checklist
The pull force at 0.9 MPa is 9425 N.
The rear adjuster acts as a mechanical stop that lets you shorten the nominal 160 mm stroke by up to 40 mm, providing a usable travel window of 120-160 mm. It only sets the end position and does not hold the load without live air pressure.
