About the Airtac MIJ Adjustable Cylinder MIJ25X80-30S
Dial in your forward end position on-site with the AirTAC MIJ25X80-30S, a round-body stainless steel mini cylinder featuring a 30 mm extend-stroke adjustment window. An external stop screw lets you shorten the forward travel from its 80 mm nominal length down to 50 mm without swapping parts, while the retract stroke remains full.
This double-acting actuator conforms to the ISO 6432 mounting interface for Ø25 bores, dropping directly into standard mini brackets and clevises. It uses a 1/8" port and an M10x1.25 male rod thread. The built-in magnet (-S) supports CMSG, DMSG, and EMSG position switches. Fixed TPU bumper pads decelerate the piston at the stroke ends.

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 MIJ25X80-30S Is Used
Tooling Changeover Stops
Use the 30 mm adjuster to shift the extend endpoint instantly when switching between part fixtures, saving setup time on a 245.3 N press operation.
Variable Length Diverters
Trim the forward stroke on-site to push different carton sizes onto secondary lines without changing the physical cylinder mount.
Is the Airtac MIJ Adjustable Cylinder MIJ25X80-30S the Right Cylinder?
When sizing this Ø25 bore, stepping down to a Ø20 MIJ drops the 0.5 MPa push force to 157 N, while moving up to a Ø32 MIJ increases it to 402 N. The 30 mm external adjuster is ideal for taking up mechanical tolerances during setup or covering multiple stop positions with one part number. Mount using LB foot, FA flange, or TC trunnion brackets, as the SDB pivot block is not available for this adjustable variant. The stop screw sets the forward end position but does not function as a mid-stroke lock. If the application requires the load to be held during air loss, add an external rod lock or pilot check valve, as the piston will drift without air pressure.
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 MIJ25X80-30S FAQ
The theoretical maximum force is 50 kgf at 1.0 MPa. The air port size is 1/8".
The external stop screw shortens the extend stroke by up to 30 mm, allowing you to set the exact forward position; the retract stroke remains full. The -S suffix indicates a built-in piston magnet for use with CMSG, DMSG, or EMSG sensors. The stainless steel build resists mild corrosion.
