About the Airtac MIJ Adjustable Cylinder MIJ40X50-30
Dial in a precise forward end position on-site with the AirTAC MIJ40X50-30, a round-body stainless-steel mini cylinder featuring a 30mm extend-stroke adjustment window. An external stop screw lets you shorten the forward travel from its 50mm nominal length down to 20mm without changing the unit, while retract remains full stroke.
The riveted stainless barrel and rod provide mild corrosion resistance for washdown environments, and the 1/4" port handles the air volume needed for this larger bore. Because this is a non-ISO-6432 size, it functions as a standalone round-body solution rather than a standard mini interface. Fixed TPU bumper pads decelerate the piston at the stroke ends.

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 MIJ40X50-30 Is Used
Heavy Diverter Gate
Shifts a robust routing gate on a packaging line, using the 30mm extend adjustment to fine-tune the deflection angle for varying carton widths.
Is the Airtac MIJ Adjustable Cylinder MIJ40X50-30 the Right Cylinder?
If your application requires more power than the 32mm variant offers, this model steps up to 628.3 N at the same pressure. The 30mm adjustment screw is highly useful for taking up mechanical tolerances during setup or covering several different stop positions with a single part number. Remember that the stop screw sets the end position but acts purely as a bumper; it is not a mid-stroke lock. The piston will drift on air loss, so fit an external rod lock or pilot check valve if you need to hold a suspended load. Mount using LB foot, FA flange, or TC trunnion brackets, noting that SDB pivot blocks are not available for this adjustable variant. Because this SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG sensors.
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 MIJ40X50-30 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 30mm on-site, allowing you to set a precise forward end position without swapping cylinders. The retract stroke remains full length. Because this specific SKU does not include a magnet (-S), it cannot support CMSG, DMSG, or EMSG position sensors.
