About the Airtac MICJ Adjustable Mini Cylinder MICJ16X40-20S
Dial in the forward stop on-site without swapping hardware: the MICJ16X40-20S uses an external screw to shorten the extend stroke by up to 20 mm, giving a usable forward range of 20-40 mm while retract stays full. The adjustable air cushion at both ends soaks up high-speed shock so you set the position and control the impact.
This double-acting, ISO 6432 round-body mini cylinder features a stainless-steel barrel and Ø6 mm rod for mild washdown resistance, operating at 30-800 mm/s on an M5×0.8 port. The -S suffix means a built-in magnet is present for CMSG, DMSG or EMSG sensors.

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 MICJ16X40-20S Is Used
Film Feed Tensioning
Set a 30 mm extend stop to guide packaging film, using the adjustable cushion to prevent shock spikes at 800 mm/s before the valve centers.
Light Parts Ejection
Eject small molded widgets from a tool, trimming the forward end by 20 mm so the 60 N working load taps the part free without bouncing.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ16X40-20S the Right Cylinder?
Choose this Ø16 bore when you need precise set-position moves at speed and the dual needle cushions to tame end-of-stroke impact. The external stop screw sets the extend endpoint but is not a mid-stroke lock; the piston will drift on air loss, so fit an external rod lock or pilot check valve to hold a suspended load.
Mounting follows the standard ISO 6432 mini interface (LB foot, FA flange, TC trunnion; no SDB block on this adjustable variant). Because this SKU carries the -S magnet, you can directly mount CMSG, DMSG or EMSG switches for 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 MICJ16X40-20S FAQ
The theoretical maximum force is 20.5 kgf at 1.0 MPa.
An external screw shortens the extend stroke by up to 20 mm (retract remains full), while needle valves adjust the air cushion at both ends to decelerate the piston near stroke end. The -S denotes a built-in piston magnet for CMSG, DMSG or EMSG sensors; the cushion only decelerates and does not lock the load.
