About the Airtac MICJ Adjustable Mini Cylinder MICJ40X225-20S
Dial in a precise forward stop without swapping hardware: the MICJ40X225-20S uses an external screw to shorten the extend end position by up to 20 mm on site, giving a usable forward range of 205-225 mm. This double-acting round-body mini cylinder pairs that settable reach with a needle-adjustable air cushion at both ends to soak up high-speed shock.
The stainless-steel barrel and rod shrug off mild corrosion and washdown environments. The -S suffix equips the piston with a magnet for CMSG, DMSG, or EMSG sensors.
Airtac MICJ Adjustable Mini Cylinder MICJ40X225-20S Technical Specifications
| Model | Airtac MICJ Adjustable Mini Cylinder MICJ40X225-20S |
|---|---|
| Series | MICJ mini cylinder |
| Bore size | Ø40 mm |
| Stroke | 225 mm |
| Acting type | Double acting, double rod, adjustable stroke + cushion |
| Port size | 1/4" |
| Rod thread | M12×1.25 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 800 mm/s |
| Cushion | Variable air cushion, both ends |
| Max standard stroke | Up to 500 mm |
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 MICJ40X225-20S Is Used
Vertical Lift Stop
Raises a 32 kg tote in a compact storage system, relying on the adjustable forward stop to hit the exact shelf height without hard mechanical crashes.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ40X225-20S the Right Cylinder?
There is no larger standard MICJ bore, so for loads beyond 377 N safe working, consider a twin-cylinder setup. The adjustable stop plus dual air cushions shine in fast set-position moves where you must tune the impact deceleration on site.
The stop screw sets the extend end position only; it is not a mid-stroke lock, and the cushion only decelerates near the stroke end. The piston will drift 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 here), and use the -S magnet for CMSG/DMSG/EMSG switches.
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 MICJ40X225-20S FAQ
This 40 mm bore cylinder features a 1/4" port and an M12x1.25 male rod thread. The theoretical maximum force is 128.1 kgf at 1.0 MPa.
An external screw shortens the extend stroke by up to 20 mm (usable forward range 205-225 mm); retract remains full. Needle valves adjust the air cushion at both ends to decelerate high-speed moves. The cushion is not a brake, and the piston drifts on air loss—use an external rod lock to hold a load. The -S magnet supports CMSG/DMSG/EMSG sensors.
