About the Airtac MIJ Adjustable Cylinder MIJ25X25-20
Dial in a precise forward end position on the fly with the AirTAC MIJ25X25-20. An external stop screw lets you shorten the extend stroke by up to 20 mm on site, yielding a usable forward travel of 5 to 25 mm without swapping hardware. Retract remains full stroke. This round-body, stainless-steel mini cylinder is double-acting and conforms to the ISO 6432 mounting interface for easy bracket drops.
The 1/8" port and M10x1.25 male rod thread handle robust airflow, while fixed TPU bumper pads absorb end-of-stroke impacts. Note this SKU lacks a magnet, so it cannot host position 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 MIJ25X25-20 Is Used
Staged Feed Ejection
Set a specific forward stop to eject 12.5 kg workpieces at varied distances using one cylinder, saving changeover time.
Washdown Gauging Stops
Leverage the stainless barrel and rod for mildly corrosive environments, positioning parts precisely before machining.
Is the Airtac MIJ Adjustable Cylinder MIJ25X25-20 the Right Cylinder?
The 20 mm adjustment window here is ideal for taking up mechanical tolerances or staging multiple forward stops from one part number. Mount using LB foot, FA flange, or TC trunnion brackets (SDB pivot block is not available on this adjustable variant). Because the stop screw only sets the end position and is not a mid-stroke lock, add an external rod lock or pilot check valve if the load must be held on air loss.
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 MIJ25X25-20 FAQ
It uses a 1/8" port. At 0.5 MPa the push force is 245.3 N and pull is 206.1 N. At 0.7 MPa push is 343.4 N and pull is 288.5 N. 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 5-25 mm); retract is always full. This SKU has no magnet and cannot take CMSG/DMSG/EMSG sensors. The -S variant is required for sensing.
