About the Airtac MICJ Adjustable Mini Cylinder MICJ16X300-40S
Dial in a precise forward stop on-site with the AirTAC MICJ16X300-40S, a stainless-steel round-body mini cylinder that shortens the extend stroke by up to 40 mm via an external screw. The usable extend range becomes 260-300 mm, while retract remains full length. A needle-set adjustable air cushion at both ends soaks up high-speed shock, letting you set the position and control the impact simultaneously.
Built with a corrosion-resistant stainless barrel and rod, this double-acting unit conforms to the ISO 6432 mounting interface for straightforward bracket drops. The -S suffix means a piston magnet is installed for CMSG, DMSG, or EMSG sensors, and the air port is M5×0.8.

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 MICJ16X300-40S Is Used
Package Diverting
Sorts light cartons on a line by extending 260-300 mm, relying on the adjustable air cushion to decelerate the 5.1 kg load smoothly at high cycle speeds.
Bin Lid Actuation
Opens and closes access hatches in washdown zones, benefiting from the stainless build and the on-site stop screw to set the open angle precisely.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ16X300-40S the Right Cylinder?
The external stop screw and dual air cushions shine in fast set-position moves where you need to trim the extend end without swapping hardware. Note that the stop screw sets the end position but is not a mid-stroke lock; the piston drifts on air loss, so add an external rod lock or pilot check valve for held loads. Mount via LB, FA, or TC (SDB is unavailable here), and use CMSG/DMSG/EMSG switches thanks to the -S magnet.
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 MICJ16X300-40S FAQ
The theoretical max force is 20.5 kgf at 1.0 MPa, and the air port is M5×0.8.
An external screw shortens the extend end by up to 40 mm (usable extend 260-300 mm), while the needle-set air cushion decelerates the piston at both ends. The -S suffix enables CMSG/DMSG/EMSG sensors. The cushion only decelerates and is not a mid-stroke lock.
