About the Airtac MIJ Adjustable Cylinder MIJ40X225-30
Dial in a precise forward end position on-site with the AirTAC MIJ40X225-30, a round-body stainless steel mini cylinder featuring a 30 mm extend-stroke adjustment window. An external stop screw lets you trim the forward travel down from the 225 mm nominal maximum without swapping hardware, while the retract stroke remains full length.
The riveted stainless barrel and rod resist mild corrosion and washdown environments. Because this is a non-magnet SKU, it cannot host CMSG, DMSG, or EMSG sensors; you would need the -S variant for position detection.

| 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 MIJ40X225-30 Is Used
Heavy Diverter Gate
Position heavy package routing gates on a conveyor line, using the 30 mm stroke adjuster to fine-tune the diversion angle for varying carton sizes without changing actuators.
Large Carton Flap Folder
Drive large packaging flaps into position prior to taping, dialing in the exact 195 to 225 mm forward reach to prevent crushing cartons of varying depths.
Is the Airtac MIJ Adjustable Cylinder MIJ40X225-30 the Right Cylinder?
When sizing this 40 mm bore, compare it against the adjacent MIJ32 and your load requirements. Since the MIJ40 is the largest available bore, there is no larger standard option to step up to. The 30 mm external adjuster is ideal for taking up mechanical tolerances during setup or covering multiple stop positions with a single part number.
Remember that the stop screw sets the end position but acts as no mid-stroke lock; the piston will drift if air pressure is lost, so fit an external rod lock or pilot check valve for holding loads. Mounting options include LB foot, FA flange, and TC trunnion brackets, plus CA, U, R, and CM back covers, but the SDB pivot block is not available on this adjustable-stroke 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 MIJ40X225-30 FAQ
This 40 mm bore cylinder uses a 1/4" air port and a 16 mm rod. At 0.7 MPa, push increases to 879.6 N and pull to 738.9 N. The theoretical maximum force is 128.1 kgf at 1.0 MPa.
An external stop screw shortens the extend stroke by up to 30 mm on-site, allowing you to set the forward end position anywhere from 195 to 225 mm; the retract stroke remains full length. This screw is not a mid-stroke lock or brake, and the double-acting piston will drift on air loss. Also, this non-S SKU lacks a magnet and cannot host position sensors.
