About the Airtac MICJ Adjustable Mini Cylinder MICJ40X200-20
Dial in a precise forward stop without swapping cylinders using the AirTAC MICJ40X200-20. This round-body stainless-steel mini cylinder features an external stop screw that shortens the extend stroke by up to 20 mm on site, giving you a usable forward range of 180-200 mm. A needle-adjustable air cushion at both ends soaks up high-speed shock, letting you set the position and control the impact simultaneously.
The stainless barrel and rod resist mild corrosion and washdown. Note this non-ISO-6432 SKU lacks a magnet (-S), so it cannot host CMSG/DMSG/EMSG sensors.

| 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 MICJ40X200-20 Is Used
Heavy Part Ejection
Push 32 kg machined metal parts out of a CNC enclosure at speed, relying on the 20 mm extend trim to hit the exact drop position without crashing.
Pallet Stopping
Halt heavy pallets on a 1/4" port-driven line. The dual adjustable air cushions absorb the 628.3 N impact force, preventing bounce at the end of the 200 mm stroke.
Carton Flap Folding
Fold thick cardboard flaps in washdown packaging zones. The stainless construction handles damp environments while the needle cushion softens the fast fold.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ40X200-20 the Right Cylinder?
Since 40 mm is the largest in this series, moving higher requires a different cylinder family. The adjustable stop plus dual air cushions excel in fast set-position moves where you must tune out end-of-stroke banging.
Mount using LB foot, FA flange, or TC trunnion brackets, as the SDB pivot-block is not offered on adjustable-stroke variants. Remember that the stop screw sets the end position but is not a mid-stroke lock; the piston will drift on air loss. To hold a suspended load, install an external rod lock or pilot-operated check valve.
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 MICJ40X200-20 FAQ
This 40 mm bore double-acting cylinder uses a 1/4" port and a 16 mm rod. The theoretical maximum force is 128.1 kgf at 1.0 MPa.
An external screw shortens the extend stroke by up to 20 mm (retract remains full). Needle valves adjust the air cushion at both ends to decelerate the piston near stroke end. This cylinder does not hold position on air loss; use an external rod lock for that. Because this SKU lacks the -S magnet, it cannot take position sensors.
