About the Airtac MICJ Adjustable Mini Cylinder MICJ40X200-40
Dial in a precise forward stop on-site with the AirTAC MICJ40X200-40, a round-body stainless steel mini cylinder featuring a 40 mm adjustable extend stroke. An external stop screw shortens the forward end position down to a 160 mm usable extend, while the retract stroke remains full. Tunable air cushions at both ends soak up high-speed impact, letting you set the exact position and control the deceleration without swapping hardware.
Note this non-ISO-6432 SKU lacks a magnet, so it cannot accept CMSG/DMSG/EMSG 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 MICJ40X200-40 Is Used
Heavy Carton Diverter
Pushes loaded packaging carts at high speed, using the 40 mm extend adjustment to fine-tune the diverting endpoint while the dual air cushions absorb the 628.3 N impact.
Pallet Stopper Gate
Halts 30 kg pallets on a gravity roller line; the adjustable forward stop sets the exact gate position, and the stainless build resists damp warehouse conditions.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ40X200-40 the Right Cylinder?
The adjustable 40 mm extend window and needle-set air cushions shine in fast set-position moves where you must tune the stop and absorb shock. For vertical loads, remember the piston drifts on air loss—the stop screw and cushion only decelerate near stroke end, so add an external rod lock or pilot check valve to hold position.
Mount using LB foot, FA flange, or TC trunnion brackets, plus CA, U, R, or CM back covers (SDB pivot-block is not available on this adjustable variant). Because this specific SKU has no -S magnet, it cannot support magnetic sensing; select the -S version if you require CMSG, DMSG, or 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 MICJ40X200-40 FAQ
This Ø40 double-acting cylinder uses a 1/4" port and 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 40 mm on-site, while needle valves tune the adjustable air cushions at both ends to decelerate high-speed moves. The cylinder does not hold position on air loss—the piston drifts, so use an external rod lock for vertical loads. Also, this SKU lacks a magnet and cannot take sensors.
