About the Airtac MICJ Adjustable Mini Cylinder MICJ40X160-40S
Dial in the forward stop on-site without swapping cylinders: the MICJ40X160-40S uses an external screw to shorten the extend stroke by up to 40 mm, giving a usable forward range of 120-160 mm. This round-body stainless steel mini cylinder pairs that set-position flexibility with a needle-adjustable air cushion at both ends, soaking up high-speed shock at the end of travel.
The stainless barrel and rod resist mild corrosion and washdown, and the built-in magnet (-S) supports CMSG, DMSG and EMSG sensors.

| 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 MICJ40X160-40S Is Used
Heavy Carton Sealing
Drive a sealing head at high speed into large cartons; the dual adjustable air cushions absorb the impact, while the stainless body handles light washdown.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ40X160-40S the Right Cylinder?
The adjustable stop screw and dual air cushions shine in fast set-position moves, letting you trim the extend end and control impact without external shock absorbers.
Remember that the stop screw sets the end position but is not a mid-stroke lock. The piston will drift on air loss, and the cushion only decelerates near the stroke end. To hold a load securely, add an external rod lock or pilot check valve. Mount via LB foot, FA flange or TC trunnion (SDB pivot-block is not available), and use the -S 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 MICJ40X160-40S FAQ
This 40 mm bore cylinder uses a 1/4" port.
An external screw shortens the extend stroke by up to 40 mm (retract remains full). Needle valves adjust the air cushion at both ends to decelerate high-speed moves. The cushion is not a brake, and the cylinder will drift on air loss; use an external rod lock to hold a load. The -S magnet enables CMSG, DMSG and EMSG sensors.
