About the Airtac MIJ Adjustable Cylinder MIJ25X175-40S
Trimming the forward end by up to 40 mm on site, this round-body stainless steel mini cylinder lets you set an exact extend position from 135 to 175 mm without changing the unit. The external stop screw alters only the extend stroke; retract remains full.
The stainless barrel and rod resist mild corrosion and washdown environments. The -S suffix means a piston magnet is built in for CMSG, DMSG or EMSG sensors, and the 1/8" port feeds the Ø10 mm rod.

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 MIJ25X175-40S Is Used
Staged Feed Diverters
Set precise extend stops to push mixed-size cartons on a line, trimming the stroke by up to 40 mm to accommodate different product lengths on the fly.
Washdown Sorting Gates
Leverage the stainless build for mild washdown areas, using the adjustable end position to route items accurately with a 12.5 kg vertical lift capacity.
Is the Airtac MIJ Adjustable Cylinder MIJ25X175-40S the Right Cylinder?
The 40 mm adjustment window is ideal for taking up mechanical tolerances or matching multiple stop depths in a single fixture. Because the stop screw only sets the end position, it will not lock the rod mid-stroke or hold a load on air loss—the piston will drift. Use an external rod lock or pilot check valve for holding.
Mounting options include LB foot, FA flange and TC trunnion brackets, plus CA, U, R and CM back covers. The SDB pivot block is not available on this adjustable variant. You can fit CMSG, DMSG or EMSG switches directly thanks to the included -S magnet.
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 MIJ25X175-40S FAQ
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 40 mm, letting you set the forward end position between 135 and 175 mm. Retract remains full. The -S suffix indicates a built-in piston magnet for CMSG, DMSG or EMSG sensors.
