The AirTAC MIJ Adjustable Cylinder MIJ25X75-40S 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.
Dial in a precise forward end position on-site with the AirTAC MIJ25X75-40S, a round-body stainless steel mini cylinder featuring a 40 mm extend-stroke adjustment window. An external stop screw trims the forward travel from its 75 mm nominal maximum down to 35 mm, letting you cover multiple stop distances with a single part number while retract remains full. The built-in piston magnet (-S) directly supports CMSG, DMSG, and EMSG position sensing.
The stainless barrel and rod resist mild corrosion and washdown, and the 1/8" port feeds a 10 mm rod with an M10x1.25 male thread. It conforms to the ISO 6432 mounting interface for standard mini brackets.

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

| 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 75 mm extend stroke by up to 40 mm to set exact contact points on sorting conveyors, accommodating different package sizes without swapping hardware.
Leverage the 12.5 kg vertical lift capacity to raise workpieces, using the stop screw to dial in multiple staged heights for machining or inspection stations.
The 40 mm adjustment window is ideal for absorbing mechanical tolerances or staging feeds during changeover. Remember that the stop screw only sets the end position; it is not a mid-stroke lock, so fit an external rod lock or pilot check valve if you must hold a load against air loss.
Mounting options include LB foot, FA flange, and TC trunnion, plus CA, U, R, or CM back covers, but the SDB pivot block is not offered on this adjustable variant. Fixed TPU bumper pads decelerate the stroke ends across the 30-800 mm/s speed range, keeping operation smooth without the complexity of an adjustable air cushion.
Quick checklist
It uses a 1/8" air port, a 10 mm piston rod, and an M10x1.25 male rod thread.
An external stop screw shortens the extend stroke by up to 40 mm on-site (usable extend 35-75 mm) without affecting the full retract stroke. The -S suffix indicates a built-in piston magnet for CMSG, DMSG, or EMSG sensors, and the stainless build resists mild corrosion.
