About the Airtac MICJ Adjustable Mini Cylinder MICJ40X175-20
Dial in the forward stop on site without swapping cylinders: the AirTAC MICJ40X175-20 uses an external screw to shorten the extend end position by up to 20 mm, giving a usable forward range of 155-175 mm. Retract remains full stroke. Built as a round-body stainless-steel mini cylinder with a 1/4" port and M12x1.25 male rod thread, it pairs this settable position with an adjustable air cushion at both ends to soak up high-speed shock.
The 40 mm bore delivers serious mini-cylinder thrust, pushing 628.3 N and pulling 527.8 N at 0.5 MPa. The stainless barrel and rod resist mild corrosion and washdown. Note this SKU lacks the -S magnet, so it cannot accept CMSG/DMSG/EMSG sensors.

| 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 MICJ40X175-20 Is Used
Heavy Package Diversion
Pushes 32 kg cartons at high speed onto a secondary line, using the 20 mm extend adjustment to dial in the exact push distance without crashing into the guard.
Pallet Stopper Gate
Halts incoming pallets at a wrapping station; the adjustable air cushion decelerates the 628.3 N impact load smoothly to prevent load tipping.
Clamp Press Positioning
Secures metal workpieces for a machining op, trimming the extend stroke 15 mm to accommodate varying part thicknesses while maintaining full clamping force.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ40X175-20 the Right Cylinder?
Choose this 40 mm size when you need heavier push power combined with on-the-fly extend trimming and high-speed cushioning. The external stop screw sets the end position but is not a mid-stroke lock, and the cylinder will drift on air loss, so add an external rod lock or pilot check valve for held loads. Mount via LB foot, FA flange, or TC trunnion (SDB pivot-block is not available), and select the -S variant if you need position 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 MICJ40X175-20 FAQ
The theoretical maximum force is 128.1 kgf at 1.0 MPa.
An external screw shortens the extend stroke by up to 20 mm (retract is unaffected), while needle valves adjust the air cushion at both ends to decelerate high-speed moves. The cushion only softens the end-of-stroke impact and does not lock the piston; the cylinder drifts on air loss, so use a pilot check valve for load holding. This non-S SKU cannot take sensors.
