About the Airtac MICJ Adjustable Mini Cylinder MICJ40X400-100
Dial in a precise forward stop on-site with this 40 mm bore round-body mini cylinder. An external screw shortens the extend stroke by up to 100 mm, letting you set the 400 mm travel down to 300 mm without swapping hardware. The stainless-steel barrel and rod shrug off mild washdown environments.
Note this non-magnetic SKU cannot host position sensors.

| 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 MICJ40X400-100 Is Used
Heavy Carton Diverter
Pushes heavy palletized cartons off a high-speed line. The 100 mm extend trim sets the exact push distance, while the needle cushion absorbs the impact of rapid 628 N strokes.
Large Case Flap Folding
Folds thick cardboard flaps on oversized packaging. The stainless build handles dusty environments, and the adjustable forward stop adapts to various case widths on the fly.
Pallet Stop Gate
Acts as a positive stop for incoming pallets. The 1/4" port drives enough force to halt momentum, and the air cushion prevents end-of-stroke slamming over the 400 mm travel.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ40X400-100 the Right Cylinder?
This Ø40 hits 628.3 N, making it ideal for heavy set-position moves. The adjustable stop and twin cushions excel in fast cycling, but remember the cylinder drifts on air loss—the screw sets the end position, not a mid-stroke lock. Use an external pilot check valve for holding. Mount via LB, FA, or TC (SDB is excluded), and select a -S variant if you need CMSG/DMSG/EMSG sensors.
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 MICJ40X400-100 FAQ
This 40 mm bore cylinder uses a 1/4" port. At 0.5 MPa it pushes 628.3 N and pulls 527.8 N. At 0.7 MPa it pushes 879.6 N and pulls 738.9 N. The theoretical maximum force is 128.1 kgf at 1.0 MPa.
An external screw shortens the extend stroke by up to 100 mm (usable 300-400 mm); retract remains full. Needle valves adjust the air cushion at both ends to decelerate high-speed moves. This SKU lacks a magnet for sensors, and the cushion only decelerates—it will not hold a load on air loss.
