About the Airtac MICJ Adjustable Mini Cylinder MICJ40X225-30
Dial in the forward stop on site without swapping cylinders: the AirTAC MICJ40X225-30 uses an external screw to shorten the extend stroke by up to 30 mm, giving a usable forward range of 195-225 mm. This round-body stainless steel mini cylinder pairs that settable end position with a needle-adjustable air cushion at both ends, soaking up high-speed shock so you control both the landing spot and the impact force.
The stainless barrel and rod resist mild corrosion and washdown. Note this SKU lacks a magnet, so it cannot host CMSG/DMSG/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. Note: the Ø40 bore is a larger, non-ISO-6432 size.
Theoretical Output Force (Ø40mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 528 N |
| 0.7 MPa | 739 N |
| Max (@1.0 MPa) | 108 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 MICJ40X225-30 Is Used
High-Speed Divertor
Divert heavy cartons on a conveyor at up to 800 mm/s; the dual adjustable air cushions absorb the end-of-stroke shock to prevent mechanical damage.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ40X225-30 the Right Cylinder?
The adjustable stop plus dual air cushions shine in fast set-position moves where you need to trim the extend end without mechanical rework. For holding a load on air loss, remember this cylinder drifts—the stop screw sets the end position but is not a mid-stroke lock, so add an external rod lock or pilot check valve. Mount via LB foot, FA flange, or TC trunnion (SDB is not offered), and select the -S variant if you need 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 MICJ40X225-30 FAQ
The theoretical maximum force is 128.1 kgf at 1.0 MPa.
An external screw shortens the extend stroke by up to 30 mm (retract remains full), while needle valves adjust the air cushions at both ends to decelerate the piston near stroke ends. The cushion only decelerates and is not a lock; the cylinder drifts on air loss, so use an external rod lock to hold a load. This non-S SKU cannot take a sensor.
