About the Airtac MICJ Adjustable Mini Cylinder MICJ40X450-10
Dial in a precise forward stop without swapping cylinders: the MICJ40X450-10 uses an external screw to shorten the extend end position by up to 10 mm on site, giving a usable forward range of 440-450 mm. This Ø40 round-body stainless steel mini cylinder pairs that on-site adjustability with a variable air cushion at both ends to soak up high-speed shock. It is a double-acting, riveted construction unit designed for a 1/4" port and a M12x1.25 male rod thread.
The stainless barrel and rod resist mild corrosion and washdown environments. Note this Ø40 bore is a non-ISO-6432 size, and because this specific SKU lacks the -S magnet, 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 MICJ Adjustable Mini Cylinder MICJ40X450-10 Is Used
Pallet Stop Gate
Halts heavy product flow on a washdown line where the stainless construction prevents mild corrosion, tuning the end position without changing the cylinder.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ40X450-10 the Right Cylinder?
The 10 mm extend adjuster and dual needle cushions shine in fast set-position moves where you must tune the forward stop and decelerate the load precisely. Remember the stop screw sets the end position but is not a mid-stroke lock; the piston will drift on air loss, so add an external rod lock or pilot check valve for held loads. Mount via LB foot, FA flange, or TC trunnion (SDB pivot-block is not available), and select an -S variant if you need magnetic sensing.
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 MICJ Adjustable Mini Cylinder MICJ40X450-10 FAQ
The theoretical maximum force is 128.1 kgf at 1.0 MPa.
An external screw shortens the extend stroke by up to 10 mm, while needle valves adjust the air cushions at both ends to decelerate high-speed impacts. The stop screw is not a mid-stroke lock; the piston drifts on air loss, so use an external rod lock for holding. This SKU has no magnet and cannot take sensors; you need the -S variant for CMSG/DMSG/EMSG switches.
