About the Airtac MICJ Adjustable Mini Cylinder MICJ40X200-50
Dial in the forward stop on-site without swapping cylinders: the MICJ40X200-50 uses an external screw to shorten the extend stroke by up to 50 mm, giving a usable forward range of 150-200 mm. Retract remains full length. A needle-set adjustable air cushion at both ends soaks up high-speed shock, letting you set the position and control the impact.
It features a 1/4" port, an M12x1.25 male rod thread, and a double-acting design. Note that this SKU lacks a magnet and cannot take sensors; the -S variant is required for CMSG/DMSG/EMSG switches.

| 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 MICJ40X200-50 Is Used
Heavy Carton Diverter
Pushes heavy cartons at high speed on a packaging line, using the 50 mm extend adjustment to fine-tune the diverting stop point while the dual air cushions absorb the 628 N impact.
Pallet Stop Gate
Acts as an adjustable end-stop for accumulating pallets, where the on-site stroke tuning sets the exact gate drop distance and the cushion prevents slamming under heavy inertia.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ40X200-50 the Right Cylinder?
Choose this model when you need fast, settable-position moves and high-impact deceleration. The adjustable stop screw and air cushion only decelerate near the stroke end; they do not hold position. For a held load on air loss, install an external rod lock or pilot check valve.
Mounting options include LB foot, FA flange, and TC trunnion; the SDB pivot-block is not available on this adjustable variant. Because this specific SKU has no magnet, it cannot support magnetic sensing.
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 MICJ40X200-50 FAQ
This Ø40 mm cylinder has a 1/4" port and an M12x1.25 male rod thread. At 0.5 MPa it pushes with 628.3 N and pulls with 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 stroke by up to 50 mm on-site, while a needle valve adjusts the air cushion at both ends to absorb high-speed shock. The cushion only decelerates near the end and is not a brake; the cylinder will drift on air loss, so use an external rod lock for holding. This non-S SKU has no magnet for sensors.
