About the Airtac MICJ Adjustable Mini Cylinder MICJ40X225-100
Trim the forward stop by up to 100 mm on site without swapping hardware using this AirTAC adjustable-extend mini cylinder. The MICJ40X225-100 is a double-acting, round-body stainless-steel actuator featuring a 225 mm nominal stroke that can be dialed down to 125 mm via an external screw. A needle-set adjustable air cushion at both ends soaks up high-speed shock, letting you set the exact extend position and control the impact simultaneously.
The stainless barrel and rod resist mild corrosion and washdown environments. Note that this SKU lacks a magnet and cannot accept CMSG, DMSG, or EMSG sensors; you would need the -S variant for position detection. As a larger bore, it is a round-body mini cylinder rather than an ISO 6432 interface unit.

| 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 MICJ40X225-100 Is Used
Pallet Diverter Arm
Set a custom extend position between 125 and 225 mm to deflect large pallets on a conveyor, using the stainless construction to endure mildly corrosive industrial environments.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ40X225-100 the Right Cylinder?
The 100 mm extend adjuster is perfect for fast set-position moves where you need to dial in a precise forward stop without machining spacers. The air cushion handles deceleration near the stroke end, but remember it is not a mid-stroke lock or brake.
This cylinder does not hold its load on air loss—the piston will drift if pressure drops, so add an external rod lock or pilot-operated check valve for suspended loads. Mounting options include LB foot, FA flange, and TC trunnion (the SDB pivot-block is not available on this adjustable-stroke build). Because this specific SKU has no -S magnet, it cannot host magnetic 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 MICJ40X225-100 FAQ
This Ø40 mm cylinder features a 1/4" air port and an M12x1.25 male rod thread.
An external stop screw shortens the extend stroke by up to 100 mm (usable extend 125-225 mm); 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, and the stop screw is an end-position setter, not a mid-stroke lock.
