About the Airtac MIJ Adjustable Cylinder MIJ25X50-20S
Dial in a precise forward end position on-site with the AirTAC MIJ25X50-20S, a round-body stainless steel mini cylinder that lets an external stop screw shorten the extend stroke by up to 20 mm without swapping parts. As a double-acting actuator conforming to the ISO 6432 mounting interface for Ø8-Ø25 bores, it drops directly into standard mini brackets and clevises. The stainless barrel and rod resist mild corrosion and washdown environments.
The built-in magnet (-S) supports CMSG, DMSG and EMSG position sensing. Fixed TPU bumper pads decelerate the stroke end, operating at speeds from 30 to 800 mm/s across a -20 to +70 °C range.

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 MIJ25X50-20S Is Used
Filler Nozzle Height Stop
Dials in the exact lower end position for different bottle heights on a packaging machine, leveraging the 12.5 kg vertical lift capacity to plunge nozzles accurately.
Machining Clamp Tolerance Take-up
Absorbs part-to-part dimensional variance by fine-tuning the forward clamping stop on-site, ensuring consistent 343 N hold force at 0.7 MPa across a fixture run.
Is the Airtac MIJ Adjustable Cylinder MIJ25X50-20S the Right Cylinder?
The 20 mm adjustment window is ideal for taking up mechanical tolerances during setup or covering several intermediate stop positions with one SKU. Mount using LB foot, FA flange or TC trunnion brackets, plus CA, U, R or CM back covers (SDB pivot block is not available on this adjustable variant). Pair the -S magnet with CMSG/DMSG/EMSG switches for end-of-stroke confirmation.
Remember that the stop screw sets the extend end position but is not a mid-stroke lock. A plain cylinder does not hold its load on air loss, and the piston will drift; for suspended loads, install an external rod lock or pilot-operated check valve.
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 MIJ25X50-20S FAQ
The theoretical maximum force is 50 kgf at 1.0 MPa.
An external stop screw shortens the extend stroke by up to 20 mm (usable extend 30-50 mm), while retract remains full stroke. The -S suffix indicates a built-in piston magnet for CMSG, DMSG or EMSG sensors. The stainless steel riveted build offers mild corrosion resistance.
