About the Airtac MIJ Adjustable Cylinder MIJ40X30-10
Dial in your forward travel precisely with the AirTAC MIJ40X30-10, a round-body stainless mini cylinder featuring a 10mm extend adjustment window. An external stop screw lets you trim the forward end position on-site, giving you a usable extend range of 20-30mm without changing the part number. Retract remains at the full 30mm.
It uses a 1/4" port and fixed TPU bumper pads to decelerate the stroke end. Note that this Ø40 bore is a non-ISO-6432 size, and this specific SKU lacks a magnet, so it cannot host CMSG/DMSG/EMSG sensors.

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 MIJ40X30-10 Is Used
Staged Diverting Gates
Adjust the forward stop on-site to accommodate different package sizes on a washdown line, relying on the stainless construction for mild corrosion resistance.
Pallet Positioning Stops
Set exact end positions for pallets of varying widths, using the fixed TPU bumpers to soften the impact of the 32kg vertical load capacity at the stroke end.
Is the Airtac MIJ Adjustable Cylinder MIJ40X30-10 the Right Cylinder?
The 10mm external stop screw is ideal for taking up mechanical tolerances during setup or covering multiple intermediate stop points in a single fixture. Keep in mind the stop screw only sets the end position; it is not a mid-stroke lock. If the load must be held during air loss, install an external rod lock or pilot check valve, as the piston will drift. Mounting options include LB foot, FA flange, and TC trunnion (the SDB pivot block is not available on 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 MIJ40X30-10 FAQ
The theoretical maximum force is 128.1kgf at 1.0MPa.
An external stop screw shortens the extend stroke by up to 10mm, allowing you to set the forward end position without swapping cylinders; retract remains full. This SKU does not have a magnet, so it cannot accept CMSG/DMSG/EMSG sensors—you would need the -S variant for position sensing.
