About the Airtac MICJ Adjustable Mini Cylinder MICJ16X120-20S
Dial in a precise forward stop on-site with the AirTAC MICJ16X120-20S, a stainless-steel round-body mini cylinder featuring a 20 mm adjustable extend stroke. An external stop screw lets you trim the forward end position down to 100 mm without swapping hardware, while a needle-set adjustable air cushion at both ends soaks up high-speed shock. The built-in piston magnet (-S) directly supports CMSG, DMSG, and EMSG position switches.
The stainless barrel and rod resist mild corrosion and washdown environments. It uses an M5×0.8 port and an M6x1.0 male rod thread, operating smoothly at speeds from 30 to 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 MICJ16X120-20S Is Used
Light Carton Flap Folding
Folds light packaging flaps at speed, relying on the adjustable stop to tune the flap angle perfectly without retooling the entire fixture.
Lab Sample Ejection
Ejects delicate lab samples from a test bay, using the needle-set cushion to decelerate the 120 mm stroke gently and prevent part damage.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ16X120-20S the Right Cylinder?
For lighter duty, AirTAC does not offer a smaller cushioned MICJ bore, so you would drop down to the MIJ bumper-only series. If you need more push, stepping up to the Ø20 bore raises the 0.5 MPa push force to 157 N. This MICJ16 is ideal when you need to set exact extend positions on the fly and manage impact at high speed.
The external screw sets the extend end position but acts purely as a stop, 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. You can mount via LB foot, FA flange, or TC trunnion (SDB pivot-block is unavailable here), and the -S magnet enables solid-state or reed 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 MICJ16X120-20S FAQ
The theoretical maximum force is 20.5 kgf at 1.0 MPa.
An external stop screw shortens the extend stroke by up to 20 mm (usable range 100-120 mm), while the needle-set air cushion at both ends decelerates the piston near the ends to absorb high-speed shock. The -S suffix means it includes a magnet for CMSG/DMSG/EMSG sensors.
