About the Airtac MIJ Adjustable Cylinder MIJ25X65-20S
Dial in your forward end position on the fly with the AirTAC MIJ25X65-20S, a round-body stainless steel mini cylinder built for double-acting service. An external stop screw lets you shorten the extend stroke by up to 20 mm on site, turning a 65 mm nominal stroke into a precisely tuned 45-65 mm forward movement without changing the part number. Retract remains at the full stroke length.
This riveted stainless barrel and piston rod construction handles mild corrosion and routine washdowns, dropping directly into standard ISO 6432 mini-cylinder brackets and clevises. It features a 1/8" air port, an M10x1.25 male rod thread, and fixed TPU bumper pads to decelerate the stroke ends. Because this SKU carries the -S suffix, a built-in piston magnet enables position sensing with CMSG, DMSG, or EMSG switches. Note that the stop screw sets the end position but is not a mid-stroke lock; the piston will drift on air loss unless you fit an external rod lock or pilot check valve.

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 MIJ25X65-20S Is Used
Adjustable Stop Gate
Acts as a changeable physical stop for cartons on a line, trimming the forward position by up to 20 mm on site to handle various box depths while retracting fully to clear the path.
Is the Airtac MIJ Adjustable Cylinder MIJ25X65-20S the Right Cylinder?
When sizing this 25 mm bore model, compare it against adjacent options to match your load. The MIJ25X65-20S is the right choice when your application requires about 147 N of safe working force but the exact forward stop point varies by 20 mm due to machine setup or part tolerances. You simply turn the external screw to trim the extend end, while the retract stays full.
For mounting, you can use LB foot brackets, FA flanges, or TC trunnions, but the SDB pivot block is not available on this adjustable-stroke variant. Back cover options include CA, U, R, and CM. Remember that fixed TPU bumpers absorb the end impact here, so if your application requires adjustable pneumatic cushioning, you should look at the MICJ variant instead.
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 MIJ25X65-20S FAQ
This double-acting cylinder uses a 1/8" air port and an M10x1.25 male rod thread. At 0.7 MPa, push increases to 343.4 N and pull to 288.5 N. The theoretical maximum force is 50 kgf at 1.0 MPa.
The external stop screw shortens the extend stroke by up to 20 mm, allowing you to set the forward end position between 45 mm and 65 mm; the retract stroke remains full. The -S suffix means a piston magnet is built in for use with CMSG, DMSG, or EMSG sensors. The stop screw is an end-position adjuster, not a mid-stroke lock.
