The AirTAC SAIJ160 Adjustable Cylinder SAIJ160BX260-50S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø160mm bore and 260mm 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 SAIJ160X260-50-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 260 mm travel by up to 50 mm. This creates a precise 210-260 mm usable window for fine-tuning the retract end position during commissioning without swapping out the barrel.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for position sensing. The extruded aluminum barrel carries sensor grooves on both sides, compatible with AirTAC CMSE reed and DMSE electronic solid-state switches. The rear adjuster acts purely as a mechanical stop for end-position tuning; it does not hold the load without 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 exact retract position within the 210-260 mm window during product size changes without replacing the cylinder.
Utilize the integrated magnet with DMSE solid-state sensors for precise position feedback in automated lines.
The adjustable stroke is ideal for product changeovers where the exact retract distance varies, offering a built-in external stop instead of requiring fixed-stroke SAI cylinders. For load-holding without continuous air pressure, this cylinder is insufficient; the rear stop is not a brake, so you must integrate a SAIL pneumatic lock, a BSAI clamp-lock, or an external rod lock.
To match this ISO 15552 replacement, specify a 160 mm bore, 260 mm stroke, 50 mm adjustment range, PT tapered ports, and the -S magnet option. Mounting choices are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the 260 mm stroke is relatively long, ensure external guide rails are used to support the load and prevent excessive side-loading on the M36x2 rod thread.
Quick checklist
The rear adjuster screw lets you shorten the 260 mm nominal stroke by up to 50 mm, providing a usable travel window of 210 to 260 mm. This allows you to set the exact retract end position during commissioning without adding external stops.
