About the Airtac MIJ Adjustable Cylinder MIJ25X40-10
Dial in your forward end position on-site with the AirTAC MIJ25X40-10, a double-acting round-body mini cylinder featuring a 10mm external stop-screw adjustment window. This lets you trim the extend stroke from 40mm down to 30mm without swapping parts, taking up mechanical tolerances directly at the fixture. Retract remains a full 40mm stroke.
Built with a stainless-steel barrel and rod for mild corrosion resistance, it conforms to the ISO 6432 mounting interface for standard mini brackets. The 1/8" port and fixed TPU bumper pads ensure reliable operation up to 800 mm/s.

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 MIJ25X40-10 Is Used
Staged Transfer Stops
Fine-tune the forward stop position on the fly for mixed-product conveyor lines, dialing in the exact 30-40mm extend length needed for each part.
Adjustable Flap Folders
Set the precise extend endpoint to fold varying carton sizes, using the 206 N pull force to retract cleanly for the next cycle.
Is the Airtac MIJ Adjustable Cylinder MIJ25X40-10 the Right Cylinder?
When sizing this 25mm bore, stepping down to a 20mm MIJ drops the 0.5 MPa push force to 157 N, while moving up to a 32mm bore increases it to 402 N. The 10mm extend adjuster is invaluable for changeover jobs, letting one unit cover several forward stops. Note that the stop screw sets the end position but is not a mid-stroke lock; the piston will drift on air loss, so add an external rod lock or pilot check valve for held loads. Mount via LB, FA, or TC brackets (SDB is unavailable here), and since this SKU lacks the -S magnet, it cannot accept CMSG/DMSG/EMSG sensors.
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 MIJ25X40-10 FAQ
The theoretical maximum force is 50 kgf at 1.0 MPa. It uses a 1/8" air port and an M10x1.25 male rod thread.
An external stop screw shortens the extend stroke by up to 10mm on-site, allowing a usable forward range of 30-40mm; the retract stroke remains fixed at 40mm. This screw only sets the end position and is not a mid-stroke lock. The cylinder drifts on air loss, so use a pilot check valve for load holding. This non-S SKU also lacks a magnet for sensors.
