The AirTAC MIJ Adjustable Cylinder MIJ25X20-20 is a genuine double acting, double rod, adjustable stroke round-body mini air cylinder with a Ø25mm bore and 20mm 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 MIJ25X20-20, a round-body stainless-steel mini cylinder built for double-acting operation. An external stop screw lets you shorten the extend stroke by up to 20 mm, absorbing setup tolerances without swapping hardware. Retract travel remains full length, while fixed TPU bumper pads decelerate the piston at the ends.
The stainless barrel and rod resist mild corrosion, and the 1/8" port feeds a Ø10 mm rod with an M10x1.25 male thread. Note this SKU lacks a magnet, so it cannot host CMSG/DMSG/EMSG sensors.

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).

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

| -S | Optional built-in magnet for CMSG / DMSG / EMSG sensors. |
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.
Quickly readjust the ejection reach during production line changeovers, using the external stop screw to dial in the precise extend endpoint.
The 20 mm adjustment window is ideal for changeover jobs, letting one part number cover several stop distances by trimming the extend end only.
Remember the stop screw sets the end position but acts as no mid-stroke lock; the piston drifts on air loss, so add an external rod lock or pilot check valve for held loads. Mount via LB foot, FA flange, or TC trunnion, as the SDB pivot-block is unavailable here. To add position sensing, select the -S magnet variant instead of this non-magnet SKU.
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. It uses a 1/8" air port and a Ø10 mm piston rod with an M10x1.25 male thread.
An external stop screw shortens the extend stroke by up to 20 mm on-site, but retract remains full and the screw is not a mid-stroke lock. This SKU has no magnet and cannot take CMSG/DMSG/EMSG sensors; you must choose the -S variant for position sensing.
