About the Airtac MICJ Adjustable Mini Cylinder MICJ16X125-30
Trim the forward stop by up to 30 mm on site without swapping hardware using this stainless-steel round-body mini cylinder. The external screw shortens the extend end position to dial in a usable 95-125 mm forward travel, while the retract stroke remains full. A needle-set adjustable air cushion at both ends soaks up high-speed shock so you control both the end position and the impact deceleration.
The riveted stainless construction resists mild corrosion and washdown. It uses the ISO 6432 mounting interface for standard mini brackets and features an M5×0.8 port. Note this SKU lacks a magnet and cannot take a sensor; order the -S variant for CMSG/DMSG/EMSG switches.

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 MICJ16X125-30 Is Used
Light Parts Ejector
Ejects small plastic parts at speed, using the 30 mm extend trim to hit the exact drop point while the air cushion absorbs the impact for quiet operation.
Sorter Diverter
Diverts lightweight items on a conveyor by dialing in a 100 mm extend stroke from the 125 mm nominal, preventing hard stops with the needle cushion.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ16X125-30 the Right Cylinder?
If you need less force, there is no smaller cushioned MICJ size, so step down to the MIJ bumper-only series. The adjustable stop plus dual air cushions excel in fast set-position moves where you must tune the forward impact.
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 to hold a suspended load. Mount via LB foot, FA flange, or TC trunnion (SDB pivot-block is unavailable). Speed ranges from 30-800 mm/s.
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 MICJ16X125-30 FAQ
The theoretical max force is 20.5 kgf at 1.0 MPa. The air port is M5×0.8.
An external screw shortens the extend stroke by up to 30 mm, while a needle valve adjusts the air cushion at both ends to decelerate high-speed moves. The cushion only absorbs shock near the end of travel; it is not a brake. This SKU has no magnet, so it cannot take a sensor.
