About the Airtac MIJ Adjustable Cylinder MIJ40X225-75
Dial in a precise forward end position on-site with the AirTAC MIJ40X225-75, a round-body stainless mini cylinder featuring a 75mm adjustable extend window. An external stop screw lets you shorten the forward stroke from its 225mm nominal maximum down to 150mm without changing the unit, while retract remains full. The stainless-steel barrel and piston rod supply mild corrosion and washdown resistance for demanding industrial environments.
Fixed TPU bumper pads decelerate the stroke ends, and because this specific SKU lacks the -S magnet option, it cannot accept position sensors.

| Rod thread | M12×1.25 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 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. Note: the Ø40 bore is a larger, non-ISO-6432 size.
Theoretical Output Force (Ø40mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 528 N |
| 0.7 MPa | 739 N |
| Max (@1.0 MPa) | 108 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 MIJ40X225-75 Is Used
Staged Material Diversion
Set the exact push-off distance for varying box widths on a packaging line.
Tolerance Take-Up in Clamping
Dial in the forward clamp position to compensate for part variability. The external screw lets you fine-tune the 225mm extend stroke without shimming, delivering consistent clamping at 0.5 MPa.
Adjustable Lift Stops
Control vertical lifting strokes for palletized goods.
Is the Airtac MIJ Adjustable Cylinder MIJ40X225-75 the Right Cylinder?
The 75mm external stop screw is ideal for taking up mechanical tolerances during setup or covering multiple intermediate stop points with a single part number. You can mount this cylinder using LB foot, FA flange, or TC trunnion brackets, but the SDB pivot-block is not available on this adjustable-stroke variant.
Keep in mind that the stop screw only trims the extend end position; it is not a mid-stroke lock or brake. The piston will drift if air pressure is lost or the valve is centered, so you must use an external rod lock or pilot-operated check valve to hold a suspended load safely. To add position sensing, you would need to select the -S magnet version to enable CMSG, DMSG, or EMSG switches.
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 MIJ40X225-75 FAQ
The theoretical maximum force is 128.1 kgf at 1.0 MPa.
An external stop screw shortens the extend stroke by up to 75mm on-site, allowing you to set the forward end position anywhere between 150mm and 225mm. The retract stroke remains full. Note that this SKU lacks a magnet, so it cannot use CMSG/DMSG/EMSG sensors, and the stop screw is not a mid-stroke lock.
