About the Airtac MIJ Adjustable Cylinder MIJ40X450-30S
Dial in a precise forward end position on-site with the AirTAC MIJ40X450-30S, a round-body stainless mini cylinder featuring a 30 mm extend-stroke adjustment window. An external stop screw lets you trim the forward stroke down from the 450 mm nominal maximum, allowing one part number to cover several stop distances without swapping hardware. Retract remains full stroke. The stainless-steel barrel and piston rod resist mild corrosion and washdown environments.
The built-in piston magnet (-S) supports CMSG, DMSG, and EMSG position switches. Fixed TPU bumper pads decelerate 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 MIJ40X450-30S Is Used
Pallet Diversion Gate
Trim the 450 mm extend stroke by up to 30 mm to perfectly align a diversion gate with varying pallet widths without re-engineering the mount.
Staged Tray Pusher
Use the adjustable forward end position to push varying tray sizes onto a packing line, dialing in the exact 420-450 mm feed distance on-site.
Is the Airtac MIJ Adjustable Cylinder MIJ40X450-30S the Right Cylinder?
The external adjuster is ideal for taking up mechanical tolerances during setup or staging feeds across a 420-450 mm extend range. Remember the stop screw only sets the end position; it is not a mid-stroke lock. The piston will drift on air loss, so specify an external rod lock or pilot check valve for held loads.
Mounting options include LB foot, FA flange, and TC trunnion brackets, plus CA, U, R, and CM back covers. The SDB pivot block is not available on this adjustable variant. Because this SKU includes the -S magnet, you can directly mount CMSG, DMSG, or EMSG sensors for end-position confirmation.
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 MIJ40X450-30S FAQ
This 40 mm bore cylinder uses a 1/4" port. The theoretical maximum force is 128.1 kgf at 1.0 MPa.
An external stop screw shortens the extend stroke by up to 30 mm, giving a usable forward range of 420-450 mm. Retract is always full stroke. The -S suffix means a piston magnet is built in for CMSG, DMSG, or EMSG sensors. Fixed TPU bumpers decelerate the ends.
