About the Airtac MICJ Adjustable Mini Cylinder MICJ40X225-40
Trim the forward stop by up to 40 mm on site without swapping hardware using this stainless round-body mini cylinder. The MICJ40X225-40 is a double-acting actuator featuring a 225 mm stroke that can be shortened to 185 mm via an external screw, paired with an adjustable air cushion at both ends to soak up high-speed shock.
The stainless steel barrel and rod resist mild corrosion and washdown environments. Note that this SKU lacks a magnet and cannot accept CMSG, DMSG, or EMSG sensors.

| 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 |

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 MICJ40X225-40 Is Used
Heavy Package Diversion
Pushes 32 kg cartons off a main belt at high speed, using the 40 mm extend trim to dial in the exact pusher distance and the air cushion to prevent end-of-stroke slamming.
Pallet Stopper Gate
Acts as a robust physical stop for 40 mm bore loads, retracting fully to let pallets pass and extending 185 mm to halt the next item gently without bounce.
Vertical Material Lowering
Lowers a 30 kg fixture smoothly, relying on the adjustable cushion to decelerate the mass safely before it reaches the bottom of the 225 mm stroke.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ40X225-40 the Right Cylinder?
The external stop screw and dual needle cushions excel in fast set-position moves where you must dial in the exact 185-225 mm extend endpoint and control impact.
Mount using LB foot, FA flange, or TC trunnion brackets, noting that the SDB pivot-block is not available on this adjustable variant. The stop screw and cushions only decelerate near stroke end; they do not function as a mid-stroke lock. Because the piston drifts on air loss, install an external rod lock or pilot check valve to hold a suspended load.
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 MICJ40X225-40 FAQ
The theoretical maximum force is 128.1 kgf at 1.0 MPa.
An external screw shortens the extend stroke by up to 40 mm (usable range 185-225 mm) while the retract remains full. Needle valves adjust the air cushion at both ends to decelerate the piston at high speed. This SKU has no magnet, so it cannot take sensors; the -S variant is required for CMSG, DMSG, or EMSG switches.
