About the Airtac MICJ Adjustable Mini Cylinder MICJ40X40-10S
Dial in a precise forward stop on-site with the AirTAC MICJ40X40-10S, a round-body stainless steel mini cylinder featuring a 10mm adjustable extend stroke. An external screw trims the extend end position down from the 40mm nominal maximum, while the retract stroke remains full length. The built-in piston magnet (-S) supports CMSG, DMSG, and EMSG sensors for exact position detection.
Needle-set adjustable air cushions at both ends soak up high-speed shock, while the stainless barrel and rod resist mild corrosion and washdown environments. It operates at speeds from 30 to 800 mm/s and uses a 1/4" port.

| Series | MICJ mini cylinder |
| Bore size | Ø40 mm |
| Stroke | 40 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 |
| Max standard stroke | Up to 500 mm |
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 MICJ40X40-10S Is Used
Heavy Diverter Gate
Shifts heavy packages on a conveyor by up to 40mm.
Carton Sealing Press
Drives a sealing head down at high speed. The dual adjustable air cushions absorb the end-of-stroke impact, protecting the package and the 16mm piston rod from shock.
Parts Ejector
Ejects dense machined parts from a fixture. The -S magnet triggers an EMSG sensor to confirm ejection, and the stainless build resists cutting fluid washdown.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ40X40-10S the Right Cylinder?
The adjustable extend stop and dual air cushions excel in fast set-position moves where you must tune the forward impact without swapping cylinders.
The stop screw sets the end position but is not a mid-stroke lock, and the cylinder will drift on air loss—use an external rod lock or pilot check valve for held loads. Mount via LB foot, FA flange, or TC trunnion (SDB pivot-block is not available). Position sensing requires the -S magnet fitted here to work with 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 MICJ40X40-10S FAQ
This 40mm bore double-acting cylinder uses a 1/4" port. At 0.5 MPa it pushes with 628.3 N and pulls with 527.8 N. At 0.7 MPa it pushes with 879.6 N and pulls with 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 10mm on-site, while the retract stroke remains full. Needle-set adjustable air cushions at both ends decelerate the piston near stroke ends to absorb high-speed shock. The cushion only decelerates and does not lock or hold position; the piston will drift on air loss, so use an external rod lock for held loads.
