About the Airtac MIJ Adjustable Cylinder MIJ40X225-20
Dial in a precise forward end position on-site with the AirTAC MIJ40X225-20, a round-body stainless steel mini cylinder built for double-acting operation. An external stop screw lets you shorten the extend stroke by up to 20 mm, providing a usable forward range of 205 to 225 mm without changing the physical cylinder. This on-site adjustability is ideal for taking up mechanical tolerances or handling changeovers, while the retract stroke remains full length.
The stainless-steel barrel and piston rod supply mild corrosion resistance for washdown environments, and the unit runs at 30-800 mm/s on a 1/4" port with an M12x1.25 male rod thread. Fixed TPU bumper pads decelerate the stroke ends, and because this SKU lacks a magnet, it cannot host CMSG, DMSG, or EMSG sensors without switching to the -S variant.

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 MIJ40X225-20 Is Used
Product Diversion
Act as a heavy-duty diverter on a packaging line, where the adjustable forward stop allows operators to change the extend reach for various box widths without swapping hardware.
Pallet Changeover
Push or index heavy loads during pallet changeover routines, relying on the stainless construction to endure mildly corrosive industrial environments while dialing in the stroke tolerance.
Is the Airtac MIJ Adjustable Cylinder MIJ40X225-20 the Right Cylinder?
The 20 mm external adjuster is perfect for setting exact forward stops during setup, but remember the screw only trims the extend end and does not function as a mid-stroke lock.
Because a standard double-acting cylinder drifts on air loss, you must add an external rod lock or pilot-operated check valve to hold a suspended load safely. For mounting, you can utilize 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-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 MIJ40X225-20 FAQ
This 40 mm bore cylinder uses a 1/4" port and an M12x1.25 male rod thread.
An external stop screw shortens the extend stroke by up to 20 mm on-site, yielding a 205-225 mm forward range, while retract remains full. This SKU has no magnet and cannot take CMSG, DMSG, or EMSG sensors; you must specify the -S variant for position sensing.
