About the Airtac MIJ Adjustable Cylinder MIJ40X20-10
Dial in a precise forward end position on the fly with the AirTAC MIJ40X20-10, a double-acting round-body mini cylinder featuring a 10mm extend-stroke adjustment window. An external stop screw lets you trim the usable forward travel down to 10mm from the 20mm nominal stroke, absorbing setup tolerances without changing the mounting. Because retract travel remains full, you get predictable return behavior while customizing the work stroke.
It uses a 1/4" port and a male M12x1.25 rod thread, relying on fixed TPU bumper pads to decelerate the stroke end. Note this SKU lacks the -S magnet, so it cannot accept CMSG, DMSG, or EMSG sensors.

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 MIJ40X20-10 Is Used
Heavy Diverter Gate
Adjust the forward stroke on-site to route varying package sizes on a conveyor, using the 32 kg vertical lift capacity to move heavier goods.
Carton Flap Folding
Dial in the exact flap contact point during format changeovers, absorbing mechanical tolerances quickly without swapping out the cylinder body.
Is the Airtac MIJ Adjustable Cylinder MIJ40X20-10 the Right Cylinder?
The 10mm external stop screw is ideal for taking up mechanical slack during changeovers. Mount using LB foot, FA flange, or TC trunnion brackets, or CA, U, R, and CM back covers (SDB pivot-block is not available on this adjustable variant). Remember 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 MIJ40X20-10 FAQ
It uses a 1/4" air port and a male M12x1.25 rod thread.
An external stop screw shortens the extend stroke by up to 10mm on-site, allowing a usable forward travel of 10-20mm, while retract remains full stroke. This SKU does not include a magnet (-S), so it cannot accept CMSG, DMSG, or EMSG sensors; fixed TPU bumper pads decelerate the stroke end.
