The AirTAC MIJ Adjustable Cylinder MIJ25X25-20S is a genuine double acting, double rod, adjustable stroke round-body mini air cylinder with a Ø25mm bore and 25mm 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 by up to 20 mm via an external stop screw, this double-acting round-body mini cylinder lets you dial in the exact extend position from 5 to 25 mm without changing parts. The retract stroke remains full.
Conforming to the ISO 6432 mounting interface for standard mini brackets, the unit features a 1/8" air port and M10x1.25 male rod thread. Because this SKU includes the -S magnet, it supports CMSG, DMSG and EMSG sensors for end-position detection. Fixed TPU bumper pads decelerate the piston at the stroke extremes.

| 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.
Adjust the forward stop on-site to alter the diverting depth for different carton widths without swapping out the entire cylinder.
Fine-tune the extend end to trigger a 12.5 kg vertical lift mechanism precisely, accommodating varying pallet heights quickly.
The 20 mm on-site stop window is ideal for taking up mechanical tolerances or staging feeds during changeovers. The stop screw sets the forward end position but is not a mid-stroke lock; the piston will drift on air loss, so fit an external rod lock or pilot check valve to hold a suspended load. Mount using LB foot, FA flange or TC trunnion brackets (SDB pivot-block is unavailable here).
Quick checklist
The theoretical maximum force is 50 kgf at 1.0 MPa. The air port is 1/8".
An external stop screw shortens the extend stroke by up to 20 mm on-site, while the retract stroke remains full. The built-in -S magnet allows CMSG, DMSG and EMSG sensors to detect piston position.
