About the Airtac MICJ Adjustable Mini Cylinder MICJ40X100-40S
Dial in exact forward stops on-site with this 40 mm round-body stainless mini cylinder, which uses an external screw to shorten the extend stroke by up to 40 mm. The usable extend range becomes 60-100 mm, while retract remains full. A variable air cushion at both ends soaks up high-speed shock, letting you set the position and control the impact simultaneously.
It carries a built-in magnet (-S) for CMSG, DMSG, or EMSG sensors, and uses a 1/4" port.

| Model | Airtac MICJ Adjustable Mini Cylinder MICJ40X100-40S |
|---|---|
| Series | MICJ mini cylinder |
| Bore size | Ø40 mm |
| Stroke | 100 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 |
| Cushion | Variable air cushion, both ends |

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 MICJ40X100-40S Is Used
Heavy Diverter Gate
Shifts a loaded diverting arm precisely, using the 40 mm extend stop to tune the gate angle without moving brackets, while the dual cushions absorb the 32 kg load impact.
Carton Flap Folder
Folds heavy corrugated flaps at speed; the adjustable forward stop dials the fold depth perfectly, and the needle-set air cushions prevent end-of-stroke slamming.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ40X100-40S the Right Cylinder?
The 40 mm extend stop plus dual cushions shine in fast set-position moves where you must tune the forward end without swapping cylinders. Mount using LB foot, FA flange, or TC trunnion (SDB pivot-block is not available on this adjustable variant).
The stop screw sets the end position but is not a mid-stroke lock. A plain cylinder does not hold its load on air loss—the piston drifts and the cushion only decelerates near the stroke end. For a held load, specify 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 MICJ40X100-40S FAQ
The theoretical maximum force is 128.1 kgf at 1.0 MPa.
An external screw shortens the extend end by up to 40 mm (usable extend 60-100 mm), while a needle valve adjusts the dual air cushions to decelerate high-speed shock. The -S suffix means it has a built-in magnet for CMSG, DMSG, or EMSG sensors.
