About the Airtac MIJ Adjustable Cylinder MIJ25X15-20S
Dial in a precise forward end position on-site with the AirTAC MIJ25X15-20S, 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, allowing one part number to cover several stop distances without swapping hardware. The retract stroke remains full length.
The stainless barrel and rod resist mild corrosion and washdown environments. It conforms to the ISO 6432 mounting interface for standard mini brackets, uses a 1/8" port, and includes a piston magnet for CMSG, DMSG or 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.
Theoretical Output Force (Ø25mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 206 N |
| 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).

Where the Airtac MIJ Adjustable Cylinder MIJ25X15-20S Is Used
Probe Gauging Station
Use the 20 mm extend adjustment to fine-tune the exact touch point of a 12.5 kg inspection probe array without machining custom spacers.
Staged Parts Escapement
Dial in the exact feed length for a 15 mm stroke escapement, using the external stop nut to compensate for tooling wear over time.
Is the Airtac MIJ Adjustable Cylinder MIJ25X15-20S the Right Cylinder?
The 20 mm adjustment window on this model is perfect for taking up mechanical tolerances during setup or staging feeds, saving you from machining custom spacers. Mount using LB foot, FA flange or TC trunnion brackets; the SDB pivot block is not available on this adjustable variant. Position holding is not inherent—the piston will drift on air loss, so add an external rod lock or pilot check valve if the load must be maintained.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G)
- ✓ Magnet (-S) for sensors?
- ✓ Back cover (CA/U/R/CM) & mount (LB/FA/SDB/TC)
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Do not dismantle the riveted front/back covers.
- check Use correct back cover (CA/U/R/CM) & mount (LB/FA/SDB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac MIJ Adjustable Cylinder MIJ25X15-20S FAQ
Its theoretical maximum force is 50 kgf at 1.0 MPa.
An external stop screw shortens the extend stroke by up to 20 mm on-site, while the retract stroke remains full length. The -S suffix indicates a built-in piston magnet for CMSG, DMSG or EMSG sensors. Fixed TPU bumper pads decelerate the stroke end.
