About the Airtac MIJ Adjustable Cylinder MIJ25X80-20S
Dial in a precise forward end position on-site with the AirTAC MIJ25X80-20S, a stainless-steel round-body mini cylinder that drops directly into standard ISO 6432 mounting interfaces. An external stop screw lets you shorten the extend stroke by up to 20 mm, yielding a usable forward range of 60 to 80 mm without swapping parts. The retract stroke remains full length.
The 1/8" port and M10x1.25 male rod thread handle robust airflow and mounting, while the integrated piston magnet (-S) supports CMSG, DMSG, and EMSG sensors for position feedback.

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 MIJ25X80-20S Is Used
Adjustable Sealing Jaw
Set the exact 60-80 mm extend depth for sealing different pouch depths, relying on the stainless build for washdown resistance in packaging environments.
Is the Airtac MIJ Adjustable Cylinder MIJ25X80-20S the Right Cylinder?
The Ø25 hits a balanced middle ground for medium-duty tasks. The 20 mm external adjuster is ideal for absorbing mechanical tolerances or staging feeds during changeovers, letting one part number cover several stop positions.
Remember that the stop screw sets the end position but acts purely as a mechanical stop, not a mid-stroke lock. The piston will drift if air pressure drops, so fit an external rod lock or pilot check valve for held loads. For mounting, utilize LB foot, FA flange, or TC trunnion brackets (the SDB pivot block is excluded here), and rely on the fixed TPU bumper pads to decelerate the stroke end 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 MIJ25X80-20S FAQ
The theoretical maximum force is 50 kgf at 1.0 MPa. It uses a 1/8" air port.
An external stop screw shortens the extend stroke by up to 20 mm on-site (retract remains full). The -S suffix indicates a built-in piston magnet, allowing you to mount CMSG, DMSG, or EMSG sensors for position detection.
