About the Airtac MICJ Adjustable Mini Cylinder MICJ40X450-100
Dial in a precise forward stop on-site with the AirTAC MICJ40X450-100, a round-body stainless-steel mini cylinder that shortens the extend stroke by up to 100 mm via an external screw. Built as a double-acting actuator with a 450 mm nominal stroke, it yields a usable extend range of 350-450 mm while retract remains full.
A needle-set variable air cushion at both ends soaks up high-speed shock, letting you set the position and control the impact without swapping hardware. The stainless barrel and rod resist mild corrosion and washdown environments. Because this SKU lacks the -S magnet, it cannot take CMSG, DMSG, or EMSG sensors.

| Stroke | 450 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 MICJ40X450-100 Is Used
Carton Sealing Press
Brings a sealing head down on oversized cartons, relying on the adjustable air cushion to absorb the 32 kg vertical load impact at high cycle speeds.
Heavy Gate Actuation
Drives a 450 mm stroke security gate, fine-tuning the forward end position on-site to avoid mechanical hard stops while operating at up to 800 mm/s.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ40X450-100 the Right Cylinder?
For lighter push requirements, the smaller Ø32 bore provides 402.2 N at 0.5 MPa, while this Ø40 is the largest available MICJ size offering 628.3 N at 0.5 MPa. The adjustable extend stop combined with the dual air cushions is ideal for fast set-position moves where you must tune the deceleration to prevent end-of-stroke banging. Mount using LB foot, FA flange, or TC trunnion brackets, as the SDB pivot-block is not available on this adjustable variant.
Remember that the stop screw and air cushion only decelerate the piston near the stroke end; they do not function as a mid-stroke lock. A plain cylinder will drift and drop its load on air loss or when a valve is centered. If your application requires holding a suspended load, install an external rod lock or a pilot-operated check valve.
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 MICJ40X450-100 FAQ
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 range 350-450 mm), while needle-set air cushions at both ends decelerate the piston at high speed. This SKU has no -S magnet and cannot take sensors. The cylinder does not hold position on air loss; use an external rod lock for suspended loads.
