About the Airtac MICJ Adjustable Mini Cylinder MICJ40X160-50S
Dial in a precise forward stop on-site with the MICJ40X160-50S, a stainless-steel round-body mini cylinder that lets an external screw shorten the extend stroke by up to 50 mm (usable extend 110-160 mm) while the retract remains full. The -S suffix means a piston magnet is built in, ready for CMSG, DMSG, or EMSG position switches.
Beyond setting the end position, twin adjustable air cushions soak up high-speed shock at both ends of the 30-800 mm/s travel range. The stainless barrel and rod resist mild corrosion and washdown.

| 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 MICJ40X160-50S Is Used
Heavy Carton Diverting
Pushes heavy cartons at high speed on a packaging line, using the 50 mm extend adjustment to tune the push distance precisely while the air cushions absorb impact.
Parts Ejection Press
Ejects machined parts from a press bed, dialing the forward stop back from 160 mm to clear tooling changes, with the magnet enabling exact end-of-stroke confirmation.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ40X160-50S the Right Cylinder?
At Ø40 this is the largest bore in the series, offering a maximum theoretical force of 128.1 kgf. Choose this 160 mm stroke model when you need a long reach but want to trim the forward end on the fly without swapping cylinders.
The adjustable stop and needle-set cushions excel in fast set-position moves, but note the cylinder will drift on air loss—the stop screw and cushions only decelerate near the end of travel, they do not lock the load mid-stroke. For position holding, add an external rod lock or pilot check valve. Mount using LB foot, FA flange, or TC trunnion (SDB pivot-block is not offered on this variant), and rely on the internal magnet for sensor feedback.
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 MICJ40X160-50S FAQ
The theoretical maximum force is 128.1 kgf at 1.0 MPa.
An external screw shortens the extend stroke by up to 50 mm (retract is unaffected), letting you set the forward end position without moving the cylinder. Needle valves adjust the air cushion at both ends to decelerate the piston before impact. The -S indicates a built-in magnet for CMSG/DMSG/EMSG sensors; the cushions only decelerate, they do not lock the load.
