The AirTAC MIJ Adjustable Cylinder MIJ25X75-20S is a genuine double acting, double rod, adjustable stroke round-body mini air cylinder with a Ø25mm bore and 75mm 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.
Trimming the forward end position by up to 20 mm via an external stop screw, this double-acting stainless mini cylinder lets you fine-tune the extend stroke from 55 to 75 mm directly on the machine. Retract remains at the full 75 mm. The built-in -S piston magnet enables CMSG, DMSG, or EMSG position sensing.
Built to the ISO 6432 mounting interface, the Ø25 mm round-body barrel and Ø10 mm rod are riveted stainless steel for mild washdown resistance. Pneumatic supply connects via a 1/8" port, and fixed TPU bumpers absorb the stroke end impact.

Specifications follow the official AirTAC MI/MIC (ISO 6432) datasheet. Barrel & rod: stainless steel (round-body, riveted construction). Thread options: PT (blank) / G.

| 0.7 MPa | 289 N |
| 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.
Fine-tune the folding arm stop on-site to accommodate different carton depths without changing cylinders, relying on the 12.5 kg vertical lift capacity.
Set the precise forward end position for pressing small bearings or pins, absorbing end-impact with fixed TPU bumpers while the -S magnet confirms stroke completion.
The 20 mm adjustment window here is ideal for taking up mechanical tolerances or matching multiple part stops without swapping hardware. Remember the stop screw only sets the forward endpoint; it is not a mid-stroke lock, so fit an external pilot check valve if the load must hold position on air loss. You can use LB, FA, or TC mounts (SDB is excluded on this adjustable variant).
Quick checklist
The theoretical maximum force is 50 kgf at 1.0 MPa. The air port is 1/8" and the male rod thread is M10x1.25.
An external stop screw shortens the extend stroke by up to 20 mm (usable extend 55-75 mm), while retract stays at the full 75 mm. The -S suffix indicates a built-in piston magnet for CMSG, DMSG, or EMSG sensors. The stainless steel riveted build resists mild corrosion.
