About the Airtac MICJ Adjustable Mini Cylinder MICJ40X400-10S
Dial in a precise 390 to 400 mm forward stop on-site with the MICJ40X400-10S, a round-body stainless mini cylinder featuring a 10 mm extend adjuster and dual adjustable air cushions. The external screw trims the forward end position without swapping cylinders, while the needle valves soak up high-speed shock at both ends.
The built-in -S magnet supports CMSG, DMSG and EMSG sensors for exact position detection.

| Port size | 1/4" |
| Rod thread | M12×1.25 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 800 mm/s |

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 MICJ40X400-10S Is Used
Heavy Carton Diversion
Pushes heavy corrugated cartons at high speed onto a secondary line, using the 10 mm extend trim to dial in the exact push distance without crashing into the guard.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ40X400-10S the Right Cylinder?
The 10 mm extend adjustment is ideal for fast set-position moves, letting you fine-tune the forward stop without mechanical rework. Note that the stop screw sets the end position but does not act as a mid-stroke lock.
For load holding, be aware the piston will drift on air loss since the cushion only decelerates near the stroke end; use an external rod lock or pilot check valve for suspended loads. Mount using LB foot, FA flange or TC trunnion (SDB is unavailable), and leverage the -S magnet for electronic or reed switching.
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 MICJ40X400-10S FAQ
An external screw shortens the extend stroke by up to 10 mm, letting you set the forward end position precisely. Needle valves provide an adjustable air cushion at both ends to absorb high-speed shock. The -S suffix means it has a magnet for CMSG, DMSG or EMSG sensors.
