About the Airtac MICJ Adjustable Mini Cylinder MICJ40X75-30S
Trimming the forward position by up to 30 mm on-site, the AirTAC MICJ40X75-30S eliminates the need to swap cylinders when dialing in a precise 45 to 75 mm extend stop. This double-acting round-body mini cylinder pairs that external screw adjustment with a needle-set variable air cushion at both ends, soaking up high-speed shock precisely at stroke end.
The 1/4" port feeds the air supply, and the integrated -S magnet enables CMSG, DMSG, or EMSG position sensing.

| Stroke | 75 mm |
| 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 |
| Cushion | Variable air cushion, both ends |

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 MICJ40X75-30S Is Used
Heavy Part Clamping
Securely clamps dense metal castings, using the 30 mm extend adjustment to dial in the exact forward stop without re-engineering the fixture.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ40X75-30S the Right Cylinder?
When sizing this unit against the range, dropping down to the Ø32 bore drops the 0.5 MPa push force to 402.2 N, while stepping up is not an option as Ø40 is the largest available MICJ. The external stop screw and dual cushions excel in fast set-position moves, but remember the cylinder does not hold position on air loss—the piston drifts, so add an external rod lock or pilot check valve for suspended loads. Mount via LB foot, FA flange, or TC trunnion (SDB is unavailable here), and leverage the -S magnet for electronic or reed switches.
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 MICJ40X75-30S FAQ
This double-acting cylinder features a 1/4" port and a male M12x1.25 rod thread. The theoretical maximum force is 128.1 kgf at 1.0 MPa.
An external screw shortens the extend stroke by up to 30 mm on-site, while needle-set air cushions at both ends absorb high-speed shock near the ends. The -S designation means a piston magnet is built-in, allowing CMSG, DMSG, or EMSG sensors to track position.
