About the Airtac MIJ Adjustable Cylinder MIJ25X225-40
Dial in a precise forward end position on-site with the AirTAC MIJ25X225-40, a double-acting round-body mini cylinder featuring a 40 mm extend-stroke adjustment window. Rather than swapping components to hit a new stop, an external screw trims the forward travel from 225 mm down to 185 mm, while retract remains full length. Built with a stainless-steel barrel and Ø10 mm piston rod, it handles mild washdown environments and conforms to the ISO 6432 mounting interface for standard mini brackets.
It uses a 1/8" port and fixed TPU bumper pads to soften stroke ends. Note this SKU lacks a magnet, so it cannot host CMSG, DMSG or EMSG sensors without the -S variant. The stop screw sets the end position but will not lock the piston if air pressure drops.

Specifications follow the official AirTAC MI/MIC (ISO 6432) datasheet. Barrel & rod: stainless steel (round-body, riveted construction). Thread options: PT (blank) / G.
Theoretical Output Force (Ø25mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 206 N |
| 0.7 MPa | 289 N |
| Max (@1.0 MPa) | 42 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 MIJ25X225-40 Is Used
Variable Length Diverter
Trim the extend stroke by up to 40 mm to push varying carton sizes onto different conveyor lanes without physically repositioning the cylinder bracket.
Adjustable Forming Stop
Set precise packaging fold depths on the fly, utilizing the 12.5 kg lift capacity to stage materials while fine-tuning the 185 to 225 mm forward reach.
Is the Airtac MIJ Adjustable Cylinder MIJ25X225-40 the Right Cylinder?
The 40 mm adjuster is ideal for taking up mechanical tolerances during setup or covering multiple intermediate stops with one part number. Because the bumper only decelerates the stroke end, you must add an external rod lock or pilot check valve to hold a suspended load securely on air loss. Mounting options include LB foot, FA flange and TC trunnion (SDB is not available), and you must specify the -S magnet option if position sensing is required.
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 MIJ25X225-40 FAQ
The theoretical maximum force is 50 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 185-225 mm; retract remains full. This specific SKU has no magnet, so it cannot accept CMSG/DMSG/EMSG sensors unless you select the -S variant.
