About the Airtac MICJ Adjustable Mini Cylinder MICJ40X160-20
Trim the forward stop by up to 20 mm on site without swapping hardware using the AirTAC MICJ40X160-20. This double-acting, round-body stainless-steel mini cylinder pairs that adjustable extend stroke with a needle-set variable air cushion at both ends, letting you dial in the exact forward position while soaking up high-speed shock.
Because the stainless barrel and piston rod resist mild corrosion and washdown, this non-ISO-6432 unit thrives in harsher settings. Note this SKU lacks a magnet, so it cannot host CMSG/DMSG/EMSG sensors; the -S variant is required for position detection.

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 MICJ40X160-20 Is Used
High-Speed Divertor
Absorb the impact of fast 32 kg product routing using the dual adjustable air cushions, preventing end-of-stroke banging on the 1/4" port cylinder.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ40X160-20 the Right Cylinder?
The external stop screw and dual air cushions shine in fast set-position moves where you must precisely tune the 140-160 mm extend travel and decelerate smoothly. The screw sets the end position only—it is not a mid-stroke lock. If the load must be held on air loss, add an external rod lock or pilot check valve, since the piston will drift. Mount via LB, FA, or TC (SDB is unavailable), and remember this non-magnetic version cannot take a sensor.
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 MICJ40X160-20 FAQ
The theoretical maximum force is 128.1 kgf at 1.0 MPa.
An external screw shortens the extend end position by up to 20 mm, while needle valves adjust the variable air cushion at both ends to decelerate high-speed moves. This cylinder does not hold position on air loss and drifts; use an external rod lock for holding. Also, this SKU lacks a magnet, so it cannot take sensors.
