About the Airtac MICJ Adjustable Mini Cylinder MICJ40X200-40S
Dial in the forward stop on-site without swapping cylinders: the AirTAC MICJ40X200-40S uses an external screw to shorten the extend end position by up to 40 mm, giving a usable forward range of 160 to 200 mm. The stainless barrel and rod resist mild corrosion and washdown environments.
This -S variant includes a piston magnet for CMSG, DMSG, or EMSG sensors. It operates at 30-800 mm/s, uses a 1/4" port, and relies on an M12x1.25 male rod thread. Note that this 40 mm bore is a non-ISO-6432 size, and the stop screw sets the end position but does not lock the load mid-stroke.

| 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 |

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 MICJ40X200-40S Is Used
High-Speed Divertor
Absorbs the impact of fast 30-800 mm/s sorting strokes using its dual adjustable air cushions, while the stop screw sets the precise extend limit.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ40X200-40S the Right Cylinder?
When sizing this 40 mm bore, stepping down to the MICJ32 drops the 0.5 MPa push force to 402.2 N, while no larger MICJ bore exists above it. Choose this model when you need both a precise extend stop and shock control for fast moves. The adjustable air cushion only decelerates the piston near the stroke end; it is not a mid-stroke lock. If the application must hold a load on air loss, add an external rod lock or pilot check valve, as the piston will drift. Mount via LB foot, FA flange, or TC trunnion (SDB is not offered on this adjustable variant), and use the built-in magnet for position sensing.
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 MICJ40X200-40S FAQ
It uses a 1/4" air port and a 16 mm rod.
An external screw shortens the extend stroke by up to 40 mm on-site, while a needle valve adjusts the air cushion at both ends to decelerate high-speed impacts. The -S denotes a built-in magnet for CMSG, DMSG, or EMSG sensors. The cylinder does not hold position on air loss.
