The AirTAC SAIJ160 Adjustable Cylinder SAIJ160BX180-20S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø160mm bore and 180mm 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 SAIJ160X180-20-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 160 to 180 mm, allowing you to dial back the 180 mm nominal stroke by up to 20 mm during commissioning.
This variant uses a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for CMSE reed and DMSE electronic sensors. It features PT tapered port threads (G3/4) and uses the standard SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR brackets. The rear adjuster acts purely as a travel stop to fine-tune deceleration, not as a lock to hold the load without live air.

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 160 to 180 mm end position during machine setup to accommodate material thickness variations without repositioning the entire cylinder assembly.
Quickly adjust the retract stop for different product sizes on a packaging line, using the 20 mm trim window to set new end-of-stroke positions on the fly.
The 20 mm adjustable end-stop is ideal for product changeovers, letting you fine-tune the retract position without swapping cylinders or adding external stops. For load-holding without live air pressure, select a SAIL (air-released lock) or BSAI (clamp-lock) cylinder instead, as the SAIJ adjuster is only a stop.
Because this is a 180 mm stroke, side-loading is less severe than on extremely long cylinders, but the substantial 40 mm rod and M36x2 thread handle high compressive loads well. To replace an ISO 15552 cylinder, match the 160 mm bore, 180 mm stroke, 20 mm adjustment, PT G3/4 ports, and the -S magnet requirement.
Quick checklist
The rear adjuster screw lets you shorten the effective stroke by up to 20 mm, creating a 160 to 180 mm travel window. It acts as a physical stop to tune the end position, but it does not lock the load without live air pressure.
The maximum thrust is 2050 kgf at 1.0 MPa.
