About the Airtac MICJ Adjustable Mini Cylinder MICJ40X75-75S
Trim the forward stop by up to 75 mm on site without swapping hardware using the AirTAC MICJ40X75-75S. This double-acting round-body mini cylinder pairs that adjustable extend stroke with a needle-set air cushion at both ends, letting you dial in the exact forward position while soaking up high-speed shock. The stainless-steel barrel and Ø16 mm piston rod shrug off mild corrosion and washdown environments.
A 1/4" port feeds the 30-800 mm/s speed range, and the built-in magnet (-S) supports CMSG, DMSG and EMSG sensors. Note that Ø40 is a non-ISO-6432 size.

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 MICJ40X75-75S Is Used
Heavy Goods Diverter
Divert dense cartons on a packaging line at high speed; the needle-set air cushions absorb the shock of the 0.7 MPa stroke end without bouncing the load.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ40X75-75S the Right Cylinder?
When sizing this Ø40 model, compare it directly against the adjacent bores. If your payload is lighter, stepping down to the Ø32 bore drops the 0.5 MPa push force to 402.2 N; if you need more power, there is no larger MICJ bore available. The 75 mm extend adjuster is ideal for fast set-position moves where you need precise forward placement without machining spacers, while the dual air cushions tame the impact at high speeds. Mount via LB foot, FA flange or TC trunnion (the SDB pivot-block is not offered on this adjustable variant). Because the -S magnet is present, you can fit CMSG, DMSG or EMSG switches for end-of-stroke confirmation.
Keep in mind the external stop screw sets the end position but does not function as a mid-stroke lock. The air cushion only decelerates the piston near the stroke end; it will not hold the load. If your application must prevent drift on air loss or when a valve is centered, add an external rod lock or a pilot-operated check valve.
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 MICJ40X75-75S FAQ
At 0.7 MPa, push increases to 879.6 N and pull to 738.9 N. The theoretical maximum force is 128.1 kgf at 1.0 MPa. It uses a 1/4" air port and features a Ø16 mm piston rod with an M12x1.25 male thread.
An external stop screw shortens the extend stroke by up to 75 mm on-site, letting you set the exact forward end position without swapping cylinders; the retract stroke remains full. Needle-set air cushions at both ends decelerate the piston at high speeds (30-800 mm/s) but do not lock the load. The -S suffix means a piston magnet is built-in, allowing you to mount CMSG, DMSG or EMSG sensors for position detection.
