The AirTAC MIJ Adjustable Cylinder MIJ25X75-30S 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 your forward end position on the fly with the AirTAC MIJ25X75-30S, a round-body stainless steel mini cylinder that lets an external stop screw shorten the extend stroke by up to 30 mm. You get a usable forward range of 45 to 75 mm without changing the unit, while retract remains full. The -S suffix means a piston magnet is built in for position sensing.
The 1/8" port and M10x1.25 male rod thread handle robust airflow, while the stainless barrel and rod resist mild corrosion and washdown environments.

| 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).

|---|---|
| 25 | Bore size in mm. |

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.
Trim the extend stroke up to 30 mm to nudge packages of varying widths onto secondary lines without swapping actuators.
Set precise end positions for carton sealing heads, altering the 45 to 75 mm reach on site to accommodate different box heights.
When sizing this 25 mm bore, stepping down to a 20 mm MIJ drops the 0.5 MPa push force to 157 N, whereas moving up to a 32 mm bore raises it to 402 N. The 30 mm adjustment window is invaluable for taking up mechanical tolerances or staging feeds, letting one part number cover several intermediate stops. The stop screw sets the end position but is not a mid-stroke lock.
Because a plain cylinder drifts on air loss, hold suspended loads with an external rod lock or pilot check valve. Mount via LB foot, FA flange, or TC trunnion (SDB is unavailable here), and pair the -S magnet with CMSG, DMSG, or EMSG switches for sensing.
Quick checklist
At 0.5 MPa it pushes 245.3 N and pulls 206.1 N. At 0.7 MPa it pushes 343.4 N and pulls 288.5 N. The theoretical max force is 50 kgf at 1.0 MPa. The air port is 1/8".
An external screw shortens the extend stroke by up to 30 mm, but retract stays full. The -S suffix indicates a built-in piston magnet for CMSG, DMSG, or EMSG sensors. The stainless build resists mild corrosion.
