About the Airtac MICJ Adjustable Mini Cylinder MICJ40X200-30S
Dial in the forward stop without swapping cylinders: the MICJ40X200-30S uses an external screw to shorten the extend end by up to 30 mm, giving a usable forward range of 170-200 mm, while a needle-set air cushion at both ends soaks up high-speed shock.
The Ø40 bore features a 1/4" port, a Ø16 piston rod with an M12x1.25 male thread, and a built-in magnet (-S) for CMSG, DMSG, or EMSG sensors. Because it is a larger round-body mini cylinder, it falls outside the ISO 6432 mounting interface. The stainless barrel and rod resist mild corrosion and washdown, and the system runs at 30-800 mm/s.

| Stroke | 200 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 |

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 MICJ40X200-30S Is Used
Heavy Press Dampening
Pushing 628.3 N at 0.5 MPa, this 40 mm cylinder drives heavy stamping actuators while the dual air cushions absorb the high-speed end-of-stroke shock.
Pallet Stopper Gate
Use the 30 mm extend adjustment to set the exact forward stop position for varying pallet sizes without re-mounting the cylinder.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ40X200-30S the Right Cylinder?
The adjustable 30 mm extend stop plus dual air cushions shine in fast set-position moves where you must tune the forward impact without changing the hardware.
This variant includes the -S magnet for position sensing but cannot accept an SDB pivot-block. Remember that the stop screw sets the end position and the cushions only decelerate near stroke end; the piston will drift on air loss. Use an external rod lock or pilot-operated check valve if you need to hold a suspended load.
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 MICJ40X200-30S FAQ
This double-acting cylinder pushes 628.3 N and pulls 527.8 N at 0.5 MPa. At 0.7 MPa, it pushes 879.6 N and pulls 738.9 N, with a theoretical maximum of 128.1 kgf at 1.0 MPa. It uses a 1/4" air port and a Ø16 rod with an M12x1.25 thread.
An external screw shortens the extend stroke by up to 30 mm, while the needle-set air cushions at both ends decelerate the piston near the stroke ends at speeds up to 800 mm/s. The -S magnet enables CMSG/DMSG/EMSG sensors. The cylinder does not hold position on air loss; use an external rod lock for suspended loads.
