About the Airtac MICJ Adjustable Mini Cylinder MICJ40X80-100S
Dial in forward stops on-site without swapping hardware: this stainless round-body mini cylinder extends up to 80 mm, while an external stop screw shortens the extend end by up to 100 mm to hit an exact target. A needle-set variable air cushion at both ends soaks up high-speed shock, letting you set the position and control the impact simultaneously.
The stainless barrel and rod resist mild corrosion and washdown. Because this SKU includes the -S magnet, it is ready for CMSG, DMSG, or EMSG position switches. Note that Ø40 is a non-ISO-6432 size.

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 MICJ40X80-100S Is Used
Case Flap Folding
Folds heavy cardboard flaps at speed; the dual variable air cushions absorb the impact, while the external screw fine-tunes the fold depth.
Pallet Stopper Arm
Halts advancing pallets on a chain line, relying on the 32 kg vertical lift margin and the on-site extend adjustment to match pallet geometry.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ40X80-100S the Right Cylinder?
The adjustable stop plus dual air cushions shine in fast set-position moves where you need to trim the forward end without risking end-of-stroke shock. The stop screw sets the end position but is not a mid-stroke lock. If you need to hold a load on air loss, add an external rod lock or pilot check valve. Mount using LB, FA, or TC brackets (SDB is not available), and use the built-in magnet for sensors.
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 MICJ40X80-100S FAQ
The theoretical maximum force is 128.1 kgf at 1.0 MPa.
An external screw shortens the extend end by up to 100 mm (retract stays full), while a needle-set variable air cushion at both ends decelerates the piston near stroke end. This Ø40 is a non-ISO-6432 round-body mini cylinder. The -S suffix means it has a built-in magnet for CMSG, DMSG, or EMSG sensors.
