About the Airtac MIJ Adjustable Cylinder MIJ40X450-100
Dial in a precise forward end position on the factory floor with the AirTAC MIJ40X450-100, a round-body stainless-steel mini cylinder featuring a double-acting adjustable extend stroke. An external stop screw lets you shorten the forward travel by up to 100 mm on site, providing a usable extend range of 350 to 450 mm while retaining the full 450 mm retract. This allows one part number to cover several intermediate stops without changing the actuator.
Built with a stainless-steel barrel and a Ø16 mm piston rod (M12x1.25 male thread), this riveted construction resists mild corrosion and washdown environments. It delivers robust power, pushing with 628.3 N and pulling with 527.8 N at 0.5 MPa. The unit uses a 1/4" port, runs at 30-800 mm/s, and relies on fixed TPU bumper pads to decelerate the stroke end.

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 MIJ40X450-100 Is Used
Multi-Format Carton Staging
Handle varying box sizes on a single line by using the 100 mm extend adjustment to set the exact push-off distance for each format changeover without swapping actuators.
Adjustable Pallet Stops
Use the robust 527.8 N pull force and on-site stroke tuning to create a physical end-stop for pallets of differing depths, absorbing impact with the fixed TPU bumpers.
Is the Airtac MIJ Adjustable Cylinder MIJ40X450-100 the Right Cylinder?
The 100 mm adjustment window is ideal for taking up mechanical tolerances during setup or accommodating multiple part lengths on the same line. Remember that the stop screw only sets the extend end position; it is not a mid-stroke lock. The piston will drift on air loss, so install an external rod lock or pilot check valve if you need to hold a suspended load. Mount via LB foot, FA flange, or TC trunnion, noting the SDB pivot block is not offered on 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 MIJ40X450-100 FAQ
This 40 mm bore cylinder uses a 1/4" air port and a Ø16 mm rod with an M12x1.25 thread. At 0.5 MPa it pushes with 628.3 N and pulls with 527.8 N. At 0.7 MPa the push is 879.6 N and pull is 738.9 N. The theoretical maximum force is 128.1 kgf at 1.0 MPa.
An external stop screw shortens the extend stroke by up to 100 mm, giving a usable forward range of 350-450 mm, while retract remains the full 450 mm. This SKU does not have a magnet, so it cannot accept CMSG, DMSG, or EMSG sensors; you would need the -S variant for position detection.
