About the Airtac MIJ Adjustable Cylinder MIJ25X20-10S
Trimming the forward end position by up to 10 mm on-site, this stainless steel round-body mini cylinder lets you fine-tune a 20 mm extend stroke without swapping parts.
Built to ISO 6432 mounting dimensions, the Ø25 body drops into standard mini brackets and clevises while the stainless barrel and rod resist mild washdown corrosion. The -S suffix equips the piston with a magnet for CMSG, DMSG or EMSG sensors, and fixed TPU bumpers decelerate the stroke end across the 30-800 mm/s speed range.

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)

| 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 MIJ25X20-10S Is Used
Staged Diverter Stops
Set precise product halt positions on a conveyor line, tweaking the extend end by up to 10 mm during format changeovers without changing the cylinder.
Carton Flap Folding
Tune the folding arm stroke on packaging equipment to match varying box heights, relying on the stainless build for mildly humid environments.
Is the Airtac MIJ Adjustable Cylinder MIJ25X20-10S the Right Cylinder?
The external stop screw is ideal for taking up mechanical tolerances during changeover, letting one part number cover several intermediate stops within the 10 mm window.
The adjuster trims the extend end only and does not lock the piston mid-stroke; because the cylinder drifts on air loss, use an external rod lock or pilot check valve for held loads. Mount via LB foot, FA flange or TC trunnion, noting the SDB pivot block is unavailable for this adjustable variant.
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 MIJ25X20-10S FAQ
It uses a 1/8" air port. At 0.5 MPa it pushes with 245.3 N and pulls with 206.1 N. At 0.7 MPa the push is 343.4 N and pull is 288.5 N. The theoretical maximum force is 50 kgf at 1.0 MPa.
An external stop screw shortens the extend stroke by up to 10 mm on-site, giving a usable forward range of 10 to 20 mm, while retract remains full. The -S suffix means a piston magnet is built-in for CMSG, DMSG or EMSG sensors. The screw sets the end position only and does not lock the load.
