About the Airtac MICJ Adjustable Mini Cylinder MICJ40X40-10
Dial in a precise forward stop on-site with the AirTAC MICJ40X40-10, a stainless-steel round-body mini cylinder featuring a 10mm adjustable extend stroke. An external screw trims the extend end position down to 30mm without swapping cylinders, while a needle-set variable air cushion at both ends absorbs high-speed shock.
Built with a 40mm bore, 16mm rod, and a 1/4" port, it runs at 30-800 mm/s. The stainless barrel and rod resist mild corrosion and washdown environments. Note this non-magnetic SKU cannot take sensors; the -S variant is required for CMSG/DMSG/EMSG switches. The cushion only decelerates near stroke end and the stop screw sets the end position—neither acts as a mid-stroke lock against air loss.

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 MICJ40X40-10 Is Used
Product Divertor
Push heavy 32kg cartons off a belt at speed; the adjustable forward stop ensures precise routing without slamming, thanks to the dual-end cushions.
Pallet Stopper Gate
Halt inbound pallets with a robust 40mm barrier. The stainless build handles dusty logistics zones, while the cushion absorbs the kinetic hit.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ40X40-10 the Right Cylinder?
The 10mm extend adjuster plus dual air cushions shine in fast set-position moves where you must tune the forward stop and kill impact energy without re-engineering the assembly. For holding a load on air loss, add an external rod lock or pilot check valve, as the piston drifts and the cushion only decelerates. Mount via LB foot, FA flange, or TC trunnion (SDB pivot-block is unavailable here).
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 MICJ40X40-10 FAQ
This 40mm bore cylinder uses a 1/4" port. At 0.5 MPa it pushes 628.3N and pulls 527.8N. At 0.7 MPa it pushes 879.6N and pulls 738.9N. The theoretical maximum force is 128.1 kgf at 1.0 MPa.
An external screw shortens the extend stroke by up to 10mm (usable extend 30-40mm), and a needle valve adjusts the air cushion at both ends to decelerate high-speed moves. This SKU lacks a magnet for sensors (needs -S). The cushion is not a brake; for load holding on air loss, use an external rod lock.
