About the Airtac MICJ Adjustable Mini Cylinder MICJ16X40-40S
Dial in the exact forward stop on-site with the AirTAC MICJ16X40-40S, a 16 mm bore stainless-steel mini cylinder. An external stop screw shortens the extend end by up to 40 mm, while a needle-set adjustable air cushion at both ends soaks up high-speed shock. The built-in piston magnet (-S) supports CMSG, DMSG, and EMSG switches for precise position sensing.
It uses the standard ISO 6432 mounting interface and an M5×0.8 port. The stainless barrel and rod resist mild corrosion and washdown environments, and the extend adjuster sets the end position but does not lock the piston mid-stroke.

|---|---|
| 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.
Theoretical Output Force (Ø16mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 86 N |
| 0.7 MPa | 121 N |
| Max (@1.0 MPa) | 18 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 MICJ16X40-40S Is Used
Light Parts Ejection
Ejects small plastic parts at speed. The 40 mm extend trim sets the exact ejection point, while the dual air cushions absorb shock to protect the 5 kg load limit.
Carton Flap Folding
Folds light cardboard flaps on a packaging line. The stainless build handles mild washdown, and the needle cushion prevents denting the material at high cycle rates.
Sensor Positioning
Moves a small test probe into place. The -S magnet works with DMSG switches to confirm the adjusted extend position before the test sequence begins.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ16X40-40S the Right Cylinder?
If you need less force, note that smaller bores in this family use a bumper instead of an air cushion. This model shines in fast set-position moves where the 40 mm extend trim and dual air cushions prevent hard impacts. Remember that the stop screw is not a mid-stroke lock; the piston drifts on air loss, so add an external rod lock or pilot check valve to hold a suspended load. Mount via LB, FA, or TC brackets (SDB is unavailable here) and use the -S magnet for CMSG/DMSG/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 MICJ Adjustable Mini Cylinder MICJ16X40-40S FAQ
The theoretical max force is 20.5 kgf at 1.0 MPa, and the air port size is M5×0.8.
An external screw shortens the extend stroke by up to 40 mm on-site without swapping cylinders, while a needle-set adjustable air cushion at both ends decelerates the piston near the ends. The -S suffix means it has a built-in magnet for CMSG, DMSG, or EMSG sensors. The cushion only decelerates; it does not lock or hold the load.
