About the Airtac MIJ Adjustable Cylinder MIJ25X50-50S
Dial in a precise forward end position on-site with the AirTAC MIJ25X50-50S, a round-body stainless steel mini cylinder built for double-acting service. An external stop screw lets you trim the extend stroke by up to 50 mm, allowing one part number to cover several forward stops without swapping hardware. Retract remains at the full 50 mm, and the screw acts only as an end-position setter, not a mid-stroke lock.
The stainless barrel and rod resist mild corrosion and washdown environments. Because this is an -S SKU, it includes a piston magnet for CMSG, DMSG or EMSG sensors. It uses the ISO 6432 mounting interface and a 1/8" port.

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 MIJ25X50-50S Is Used
Staged Part Diversion
Set the extend stop to push components varying distances onto secondary lanes without changing the cylinder.
Tolerance Take-Up Press
Trim the forward end position to absorb mechanical tolerances and press light assemblies with repeatable contact.
Is the Airtac MIJ Adjustable Cylinder MIJ25X50-50S the Right Cylinder?
For lighter jobs, the MIJ20 bore drops the 0.5 MPa push force to 157.0 N, while stepping up to the MIJ32 raises it to 402.2 N. The 50 mm adjustment window here is ideal for taking up mechanical tolerances or staging feeds during changeovers. Remember that the stop screw merely sets the forward end position; it does not hold the load on air loss, so add an external rod lock or pilot check valve if you need to prevent drift.
This variant accepts LB foot, FA flange and TC trunnion mounts, but the SDB pivot block is not available on adjustable-stroke models. Fixed TPU bumper pads decelerate the stroke ends across the 30-800 mm/s speed range.
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 MIJ25X50-50S FAQ
The theoretical maximum force is 50 kgf at 1.0 MPa. The air port is 1/8".
The external stop screw shortens the extend stroke by up to 50 mm on-site, while retract stays at the full 50 mm. The -S suffix means it has a built-in piston magnet for CMSG, DMSG or EMSG sensors.
