About the Airtac MICJ Adjustable Mini Cylinder MICJ40X400-10
Tune the forward stop by up to 10 mm on-site with the AirTAC MICJ40X400-10, a double-acting round-body mini cylinder built from stainless steel for mild washdown resistance. A needle-set variable air cushion at both ends soaks up high-speed shock, while the 1/4" port and Ø16 rod handle serious work.
Because this is a non-ISO-6432 size, it functions purely as a robust round-body actuator rather than a standard mini interface. Note that this specific SKU lacks a magnet, so it cannot accept CMSG, DMSG, or EMSG sensors unless you upgrade to the -S variant. The external screw trims the extend stroke only (usable range 390-400 mm); it sets the end position and is not a mid-stroke lock.

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 MICJ40X400-10 Is Used
Heavy Pallet Diverter
Divert heavy pallets on a packaging line; the dual adjustable air cushions absorb the shock of the 400 mm stroke at high speed without slamming.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ40X400-10 the Right Cylinder?
The adjustable 10 mm extend stop plus dual air cushions shine in fast set-position moves where you must dial in a precise forward endpoint without swapping cylinders and control the impact at stroke end.
Remember that a plain cylinder drifts on air loss—the cushion only decelerates near the end and acts as neither a brake nor a mid-stroke lock. For suspended loads, specify an external rod lock or pilot-operated check valve. Mount using LB foot, FA flange, or TC trunnion brackets (SDB pivot-block is unavailable here), and select the -S magnet version if you require position 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 MICJ40X400-10 FAQ
This Ø40 bore cylinder features a 1/4" port and a Ø16 mm rod with an M12x1.25 male thread.
An external screw shortens the extend stroke by up to 10 mm (retract remains full), letting you set the exact forward end position. Needle valves adjust the variable air cushion at both ends to decelerate high-speed impacts. This SKU has no magnet (no sensors), and it will not hold a load on air loss—use an external rod lock for suspended loads.
