About the Airtac MIJ Adjustable Cylinder MIJ25X100-20S
Trimming the forward end position by up to 20 mm on site, this stainless-steel round-body mini cylinder removes the need to swap hardware when dialing in a 80 to 100 mm extend stroke.
The Ø25 bore uses a 1/8" port and a Ø10 mm piston rod with an M10x1.25 male thread. Because this SKU includes the -S magnet, it directly accepts CMSG, DMSG, or EMSG sensors for end-of-stroke detection. The riveted stainless barrel and rod shrug off mild washdown environments, while fixed TPU bumper pads absorb the stroke-end impact.

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 MIJ25X100-20S Is Used
Carton Flap Folding
Fine-tune the forward stroke on the fly to accommodate varying box heights without changing cylinders, using the 12.5 kg vertical lift capacity to hold flaps in place.
Tooling Changeover Stops
Set intermediate mechanical end positions for multi-product machining fixtures, relying on the stainless build to resist cutting fluid splash during rapid changeovers.
Is the Airtac MIJ Adjustable Cylinder MIJ25X100-20S the Right Cylinder?
The integrated stop screw is ideal for taking up mechanical tolerances during setup or covering multiple intermediate stops with a single part number. Remember that the adjuster only shortens the extend stroke; the retract distance remains full.
This unit relies on fixed bumper pads, so it cannot hold a load if air pressure drops—the piston will drift. For suspended loads, install an external pilot check valve or rod lock. You can mount it using LB foot, FA flange, or TC trunnion brackets (the SDB pivot block is not offered on this variant), and the -S magnet enables solid state or reed sensing.
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 MIJ25X100-20S FAQ
The theoretical maximum force is 50 kgf at 1.0 MPa.
An external stop screw shortens the extend stroke by up to 20 mm on site (retract remains full). The -S suffix denotes a built-in piston magnet, allowing you to mount CMSG, DMSG, or EMSG sensors for position detection.
