About the Airtac MICJ Adjustable Mini Cylinder MICJ40X450-30S
Dial in a precise 420 to 450 mm forward stop on-site with the AirTAC MICJ40X450-30S, a round-body stainless steel mini cylinder that eliminates the need to swap hardware for minor position changes. An external screw trims the extend stroke by up to 30 mm, while a needle-set variable air cushion at both ends soaks up high-speed shock. The built-in magnet enables CMSG, DMSG, or EMSG sensors for position tracking.
Delivering substantial thrust, this double-acting bore 40 unit pushes 628.3 N and pulls 527.8 N at 0.5 MPa. The stainless barrel and rod resist mild corrosion and washdown environments.

| 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 MICJ40X450-30S Is Used
Vertical Carton Stacker
Lifts cartons up to 32 kg safely, relying on the needle-set cushion to soften the 450 mm high-speed extend stop and the -S magnet to confirm stack height.
Heavy Film Roll Feed
Pushes large film rolls into a wrapping cradle, using the adjustable forward position to dial in tension without swapping cylinders, while the stainless rod resists washdown.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ40X450-30S the Right Cylinder?
When sizing this 40 mm bore, stepping down to a 32 mm bore drops the 0.5 MPa push force to 402.2 N, whereas this 40 mm bore provides 628.3 N; there is no larger standard bore in this series. The 30 mm extend adjuster and dual air cushions are ideal for fast, settable-position moves, letting you tune the forward stop and decelerate impact without changing the full 450 mm retract. The 1/4" port feeds the volume needed for that speed.
This cylinder does not hold position on air loss—the piston drifts, and the cushion only decelerates near the stroke end, so add an external rod lock or pilot check valve for suspended loads. Use the -S magnet with CMSG/DMSG/EMSG switches for sensing. Mount via LB foot, FA flange, or TC trunnion (SDB pivot-block is not available on this adjustable variant).
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 MICJ40X450-30S FAQ
This double-acting cylinder uses 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 30 mm (usable range 420-450 mm); retract remains full. Needle-set variable air cushions at both ends decelerate the piston near the ends to absorb high-speed shock, but this is not a mid-stroke lock. The cylinder does not hold position on air loss, so use an external rod lock for suspended loads. The -S magnet supports CMSG, DMSG, and EMSG sensors.
