About the Airtac MIJ Adjustable Cylinder MIJ40X350-100
Dial in a precise forward end position on-site with the AirTAC MIJ40X350-100, a round-body stainless-steel mini cylinder featuring a 100mm adjustable extend window. An external stop screw lets you trim the forward stroke from 250mm up to the 350mm maximum without swapping parts, while retract remains full length.
The stainless barrel and rod resist mild corrosion and washdown environments. This non-ISO-6432 Ø40 bore uses a 1/4" port and an M12x1.25 male rod thread. Note this SKU lacks a magnet, so it cannot accept CMSG/DMSG/EMSG sensors.

| Port size | 1/4" |
| 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 MIJ40X350-100 Is Used
Staged Diverter Pusher
Pushes heavy cartons at a transfer junction using the 628.3N extend force, with the 100mm stop screw tweaked to alter the push distance for different box sizes on the fly.
Adjustable Pressing Head
Applies a controlled downward clamping force on assemblies, dialing in the exact 250-350mm extend depth to prevent crushing components without changing the cylinder.
Pallet Changeover Stop
Halts pallets on a heavy-duty roller line, using the external nut to quickly shorten the extend position and accommodate varying pallet widths during production runs.
Is the Airtac MIJ Adjustable Cylinder MIJ40X350-100 the Right Cylinder?
The 100mm adjustment window is ideal for taking up mechanical tolerances during setup or covering multiple stop positions with a single part number. For mounting, choose LB foot, FA flange, or TC trunnion brackets, as the SDB pivot block is not available on this adjustable variant.
Keep in mind the stop screw sets the end position but acts purely as a mechanical stop, not a mid-stroke lock. The piston will drift if air pressure is lost or the valve is centered. To maintain a vertical load under those conditions, integrate an external rod lock or a pilot-operated check valve into your circuit.
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 MIJ40X350-100 FAQ
This double-acting Ø40 bore cylinder uses a 1/4" port and an M12x1.25 male rod thread. The theoretical maximum force is 128.1kgf at 1.0MPa.
An external stop screw shortens the extend stroke by up to 100mm on-site, giving a usable forward range of 250-350mm; the retract stroke remains fixed at full length. This specific SKU does not have a magnet, meaning it cannot accept CMSG, DMSG, or EMSG sensors. You would need the -S variant for position sensing.
