About the Airtac MIJ Adjustable Cylinder MIJ40X500-30
Dial in a precise forward end position on-site with the AirTAC MIJ40X500-30, a round-body stainless mini cylinder featuring a 30 mm extend-stroke adjustment window. An external stop screw lets you shorten the forward travel from its 500 mm nominal maximum down to 470 mm, absorbing setup tolerances without changing the cylinder body. Retract travel remains full length.
The stainless-steel barrel and Ø16 mm piston rod supply mild corrosion resistance for washdown environments. This Ø40 bore size is a non-ISO-6432 round-body format, operating at 30-800 mm/s with fixed TPU bumper pads. It uses a 1/4" port and an M12x1.25 male rod thread. This non-magnet SKU cannot host position 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 MIJ40X500-30 Is Used
Pallet Diverter
Pushes heavy pallets onto a secondary line, using the 30 mm stop screw to fine-tune the contact point for varying pallet widths.
Case Flap Folder
Holds large carton flaps during the taping sequence, adjusting the forward reach on-site to handle different box depths.
Heavy Tray Stopper
Halts incoming product trays on a gravity roller conveyor, trimming the extend stroke to take up mechanical play.
Is the Airtac MIJ Adjustable Cylinder MIJ40X500-30 the Right Cylinder?
The 30 mm external stop screw is ideal for changeover jobs, letting one part number cover several forward stops. Remember the stop screw only trims the extend end and is not a mid-stroke lock. The piston will drift on air loss, so fit an external pilot check valve for vertical load holding. Mounting options include LB, FA, and TC (SDB is unavailable), and 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 MIJ40X500-30 FAQ
The theoretical max force is 128.1 kgf at 1.0 MPa. The air port is 1/4".
An external stop screw shortens the extend stroke by up to 30 mm, allowing you to set the forward end position between 470 mm and 500 mm. The retract stroke remains full length. This SKU has no magnet, so it cannot take sensors.
