About the Airtac MICJ Adjustable Mini Cylinder MICJ40X75-40
Dial in the forward stop on-site without swapping components: the AirTAC MICJ40X75-40 shortens the extend end position by up to 40 mm via an external screw, while a needle-set air cushion at both ends soaks up high-speed shock.
The Ø40 bore features a 1/4" port, a Ø16 mm piston rod with an M12x1.25 male thread, and a stainless barrel and rod that resist mild corrosion and washdown environments. Because this specific SKU lacks the -S magnet option, it cannot accept CMSG, DMSG, or 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 MICJ40X75-40 Is Used
High-Speed Diverting
Divert dense packages on a high-speed line, relying on the dual adjustable air cushions to absorb shock and prevent end-cap damage during rapid 800 mm/s cycles.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ40X75-40 the Right Cylinder?
When sizing this 40 mm bore, stepping down to the Ø32 model drops the 0.5 MPa push force to 402.2 N, while no larger standard AirTAC round-body mini cylinder exists above Ø40. Choose this 75 mm stroke version when you need a fast, settable forward impact within a 35 to 75 mm usable extend window. The adjustable air cushion allows you to tune the deceleration curve for high-speed moves up to 800 mm/s.
Remember that the external stop screw sets only the end position; it is not a mid-stroke lock. The cylinder will drift and fail to hold a load on air loss, so add an external rod lock or pilot-operated check valve if you need true position holding. For mounting, utilize LB foot, FA flange, or TC trunnion brackets, noting that the SDB pivot-block is not available on this adjustable-stroke variant.
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 MICJ40X75-40 FAQ
At 0.7 MPa, push increases to 879.6 N and pull to 738.9 N, with a theoretical maximum of 128.1 kgf at 1.0 MPa. The air port size is 1/4".
An external screw shortens the extend stroke by up to 40 mm on-site, while the needle-set air cushion at both ends only decelerates the piston near stroke end to absorb high-speed shock—neither feature acts as a mid-stroke lock or brake. Because this SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG sensors; you would need the -S variant for position sensing.
