About the Airtac MICJ Adjustable Mini Cylinder MICJ40X150-30S
Shave up to 30 mm off the forward stop on site with the AirTAC MICJ40X150-30S, a 40 mm bore round-body stainless mini cylinder that pairs a 120-150 mm adjustable extend stroke with needle-set air cushions at both ends. The external screw trims the extend end position only, letting you dial in the exact forward reach without swapping hardware, while the cushions soak up high-speed shock.
Built with a stainless-steel barrel and rod for mild washdown resistance, this double-acting actuator runs at 30-800 mm/s. Because this SKU includes the -S magnet, it is ready for CMSG, DMSG or EMSG position switches. Note that the stop screw sets the end position but is not a mid-stroke lock; the piston will drift on air loss.

| 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 MICJ40X150-30S Is Used
High-Speed Flap Folder
Tames end-of-stroke impact on rapid folding cycles using the dual adjustable air cushions, ensuring crisp folds without hammering the assembly.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ40X150-30S the Right Cylinder?
At 40 mm, this is the largest bore in the MICJ family, pushing 628.3 N at 0.5 MPa. If your load is lighter, the 32 mm bore drops the push force to 402.2 N; there is no larger MICJ option available. Choose this 40 mm model when you need the maximum thrust of the range alongside the ability to fine-tune the extend end by up to 30 mm and use the adjustable air cushions to control impact at high speeds.
Mounting options include LB foot, FA flange and TC trunnion, plus CA, U, R or CM back covers, but the SDB pivot block is not offered on this adjustable variant. Remember that the cushion only decelerates near the stroke end and the stop screw is not a brake. If you need to hold a load vertically during air loss, add an external rod lock or pilot 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 MICJ40X150-30S FAQ
This 40 mm bore cylinder uses a 1/4" port. At 0.5 MPa it pushes 628.3 N and pulls 527.8 N. At 0.7 MPa it pushes 879.6 N and pulls 738.9 N. The theoretical maximum force is 128.1 kgf at 1.0 MPa.
An external screw shortens the extend end position by up to 30 mm, giving a usable forward range of 120-150 mm; retract remains full. Needle valves adjust the air cushions at both ends to decelerate the piston at high speed. The -S suffix means a magnet is included for CMSG/DMSG/EMSG sensors. The stop screw is not a mid-stroke lock, and the cylinder will drift on air loss, so use an external rod lock to hold a load.
