About the Airtac MICJ Adjustable Mini Cylinder MICJ40X160-30S
Dial in a precise forward stop on-site with the AirTAC MICJ40X160-30S, a round-body stainless steel mini cylinder featuring a 30 mm adjustable extend stroke. An external stop screw lets you trim the forward end position from 130 to 160 mm without swapping cylinders, while the needle-set variable air cushion at both ends soaks up high-speed shock.
The robust stainless barrel and rod resist mild corrosion and washdown environments. Because this is a -S model, a built-in piston magnet enables position sensing with CMSG, DMSG or EMSG switches.
Airtac MICJ Adjustable Mini Cylinder MICJ40X160-30S Technical Specifications

| Series | MICJ mini cylinder |
| Bore size | Ø40 mm |
| Stroke | 160 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 |
| Max standard stroke | Up to 500 mm |
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 MICJ40X160-30S Is Used
Vertical Lift Stop
Raises a 32 kg materials tote in a vertical lift station, relying on the needle-set cushion to prevent end-of-stroke slamming while the external screw sets the exact raise height.
Washdown Sorting Plow
Deploys a sorting plow in a washdown zone where the stainless barrel resists mild corrosion, using the -S magnet and DMSG sensor to confirm plow extension before items pass.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ40X160-30S the Right Cylinder?
As the largest available round-body mini cylinder in this series, there is no larger standard bore to step up to if your load exceeds the safe working capacity of roughly 377 N. The adjustable stop screw and dual air cushions are ideal for fast, settable-position moves that require precise end-stops without mechanical shock.
Remember that the stop screw sets the end position but does not function as a mid-stroke lock. A plain cylinder does not hold its load on air loss or when the valve is centered; the piston will drift, and the cushion only decelerates near the stroke end. For a held load, install an external rod lock or a pilot-operated check valve. Mount using LB foot, FA flange or TC trunnion brackets (the SDB pivot-block is not available on this adjustable 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 MICJ40X160-30S FAQ
The theoretical maximum force is 128.1 kgf at 1.0 MPa. It operates on a 1/4" port with a 16 mm rod.
The external stop screw shortens the extend stroke by up to 30 mm on-site, giving a usable forward range of 130-160 mm; the retract stroke remains full. The needle-set variable air cushion at both ends decelerates the piston near stroke ends to absorb high-speed shock. This is a -S model, meaning it includes a piston magnet for CMSG, DMSG or EMSG sensors.
