About the Airtac MIJ Adjustable Cylinder MIJ25X225-50
Dial in a precise forward end position on the fly with the AirTAC MIJ25X225-50, a round-body stainless-steel mini cylinder that lets an external stop screw shorten the extend stroke by up to 50 mm. This double-acting actuator uses a standard 225 mm stroke but yields a usable forward travel of 175 to 225 mm, allowing one part number to cover multiple stop distances while retract remains full. The built-in fixed TPU bumper pads decelerate the piston near the stroke end.
It features a 1/8" port, an M10x1.25 male rod thread, and conforms to the ISO 6432 mounting interface for easy bracket interchangeability.

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 MIJ25X225-50 Is Used
Variable Length Diverter
Trim the 225 mm extend stroke by up to 50 mm to deflect packages of varying sizes on a conveyor without changing the cylinder mounting.
Tolerance Take-up Clamp
Absorb tooling tolerances during part clamping by fine-tuning the forward end position, ensuring consistent contact without re-engineering the fixture.
Is the Airtac MIJ Adjustable Cylinder MIJ25X225-50 the Right Cylinder?
The 50 mm external adjustment window is ideal for taking up mechanical tolerances during setup or managing part changeovers without physically swapping the cylinder. Because this SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG sensors; choose the -S variant if position detection is required.
Keep in mind the stop screw only trims the extend end position and does not function as a mid-stroke lock. A plain pneumatic cylinder will drift and drop its load on air loss, so install an external rod lock or pilot-operated check valve for suspended loads. Standard mounting options include LB foot, FA flange, and TC trunnion, but the SDB pivot block is not available on this adjustable-stroke model.
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 MIJ25X225-50 FAQ
This Ø25 mm bore cylinder features a 1/8" 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.
An external stop screw shortens the extend stroke by up to 50 mm on site, giving a usable forward travel of 175 to 225 mm from the 225 mm nominal stroke. The retract stroke remains full. This screw sets the end position only and is not a mid-stroke lock. Note that this specific SKU lacks a magnet, so it cannot accept position sensors.
