About the Airtac MIJ Adjustable Cylinder MIJ40X225-40
Dial in your forward end position on-site with the AirTAC MIJ40X225-40, a round-body stainless-steel mini cylinder featuring a double-acting adjustable extend stroke. An external stop screw lets you shorten the forward travel by up to 40 mm, providing a usable extend range of 185 to 225 mm without swapping parts. The retract stroke remains full length, and the fixed TPU bumper pads decelerate the piston at the ends.
This Ø40 bore unit pushes a theoretical maximum of 128.1 kgf at 1.0 MPa. Note that this SKU lacks a magnet, so it cannot accept CMSG, DMSG, or EMSG sensors; the -S variant is required for position detection. The stop screw sets the end position but is not a mid-stroke lock, meaning the piston will drift if air pressure is lost.

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 MIJ40X225-40 Is Used
Pallet Diverter Setup
Trim the 225 mm extend stroke by up to 40 mm to dial in the exact contact point for diverting heavy pallets without repositioning the entire cylinder assembly.
Staged Press Operations
Set a precise lower end stop for light pressing tasks, leveraging the 32 kg vertical lift capacity to seat components before the full stroke completes.
Is the Airtac MIJ Adjustable Cylinder MIJ40X225-40 the Right Cylinder?
Since there is no larger standard MIJ bore, if your application exceeds the 128.1 kgf theoretical maximum, you must switch to a different cylinder family. The 40 mm adjustment window is ideal for taking up mechanical tolerances or staging feeds across changeover jobs.
Remember that the external stop screw only trims the extend end position—it does not function as a brake. If your load must be held vertically during a loss of air pressure, add an external rod lock or a pilot-operated check valve. For mounting, you can use LB foot, FA flange, or TC trunnion brackets, along with CA, U, R, or CM back covers, but 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 MIJ40X225-40 FAQ
This double-acting cylinder uses a 1/4" port and a Ø16 mm rod with an M12x1.25 male thread. 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 40 mm on-site, giving a usable forward range of 185 to 225 mm, while retract remains full. This screw sets the end position but is not a mid-stroke lock; the piston will drift on air loss. Additionally, this non-S SKU lacks a magnet, so it cannot accept position sensors.
