The AirTAC MIJ Adjustable Cylinder MIJ25X35-20S is a genuine double acting, double rod, adjustable stroke round-body mini air cylinder with a Ø25mm bore and 35mm stroke, 1/8" air ports and a stainless-steel barrel and rod for mildly corrosive environments. Its ISO 6432 mounting interface fits standard ISO 6432 mini-cylinder mounting interfaces.
Dial in a precise forward end position on-site with the AirTAC MIJ25X35-20S, a round-body stainless steel mini cylinder featuring a 20 mm extend-stroke adjustment window. An external stop screw lets you shorten the forward travel from its 35 mm nominal length down to 15 mm without swapping components, while retract remains full stroke. Built with a riveted stainless barrel and rod, it handles mild washdown environments and conforms to the ISO 6432 mounting interface for standard mini brackets.
The -S suffix indicates a built-in piston magnet for CMSG, DMSG, or EMSG sensors, and the 1/8" air port supplies the volume needed for its 30-800 mm/s speed range.

| Max (@1.0 MPa) | 42 kgf |
MIJ / MICJ are double-rod: the rear rod that carries the stroke adjuster exits the rear cover, so both piston faces lose rod area. The rod-side (annular) area is used for both directions (conservative).

MI-family variants: MI / MIC (double acting ±cushion), MSI / MTI (single acting push / pull), MID / MICD (double rod ±cushion), MIJ / MICJ (double rod, adjustable stroke ±cushion). Back covers CA / U / R / CM. Mounting LB / FA / SDB / TC.
Use the adjustable forward end position to create staged material stops for different bend depths, leveraging the 12.5 kg vertical lift capacity to hold workpieces.
Fine-tune the forward stroke on the fly to match fluctuating package heights without changing cylinders, relying on the fixed TPU bumper pads to soften the impact.
Choose the MIJ25 when your application requires that middle ground of 245.3 N. The 20 mm external stop screw is ideal for taking up mechanical tolerances or staging feeds, allowing one part number to cover several intermediate stops. Remember that the stop screw only trims the extend end; it is not a mid-stroke lock. The piston will drift on air loss, so fit an external rod lock or pilot check valve if you need to hold a suspended load.
Mounting options include LB foot brackets, FA flanges, and TC trunnions, but the SDB pivot block is not available on this adjustable-stroke variant. Because this SKU includes the -S magnet, you can directly mount CMSG, DMSG, or EMSG switches for position sensing.
Quick checklist
This 25 mm bore cylinder uses a 1/8" air port and a male M10x1.25 rod thread.
An external stop screw shortens the extend stroke by up to 20 mm on-site, giving a usable forward range of 15 to 35 mm, while retract remains full stroke. The -S suffix means it has a built-in piston magnet for CMSG, DMSG, or EMSG sensors. The stainless steel build provides mild corrosion resistance.
