About the Airtac MIJ Adjustable Cylinder MIJ40X225-100
Dial in a precise forward end position on-site with the AirTAC MIJ40X225-100, a round-body stainless mini cylinder featuring a 100mm adjustable extend window. A stop screw lets you trim the usable forward stroke down from the 225mm nominal maximum, absorbing setup tolerances or accommodating multiple stop points from a single part number. Retract travel remains full length.
It uses a 1/4" port and a 16mm rod with an M12x1.25 male thread. Fixed TPU bumper pads decelerate the stroke ends. This SKU lacks a magnet, so it cannot accept CMSG, DMSG, or EMSG sensors; choose the -S variant for position sensing.

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 MIJ40X225-100 Is Used
Adjustable Carton Sealing
Fine-tune the forward end position to match different flap heights on a packaging line, using the 32 kg vertical lift capacity to hold flaps securely during taping.
Is the Airtac MIJ Adjustable Cylinder MIJ40X225-100 the Right Cylinder?
The external adjuster is ideal for changeover jobs where you need staged feeds without machining custom spacers. Mount using LB foot, FA flange, or TC trunnion brackets, plus CA, U, R, or CM back covers. The SDB pivot-block is not available on this adjustable-stroke variant. Remember that the stop screw sets the end position but is not a mid-stroke lock; the piston will drift on air loss, so fit an external rod lock or pilot check valve for held loads.
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 MIJ40X225-100 FAQ
This 40mm bore cylinder uses a 1/4" port and a 16mm rod. The theoretical maximum force is 128.1 kgf at 1.0 MPa.
An external stop screw shortens the extend stroke by up to 100mm on-site, giving a usable forward range of 125-225mm; retract remains full. The screw only sets the end position and does not lock the piston. On air loss the cylinder drifts, so use an external rod lock for holding. This non-S SKU has no magnet and cannot take sensors.
