About the Airtac MICJ Adjustable Mini Cylinder MICJ40X175-40
Dial in a precise forward stop on-site with the AirTAC MICJ40X175-40, a round-body stainless steel mini cylinder featuring a 40 mm adjustable extend stroke. An external stop screw lets you trim the extend end position down from the 175 mm maximum, while a needle-set adjustable air cushion at both ends soaks up high-speed shock.
Built with a mildly corrosion-resistant stainless barrel and rod, this 1/4" ported unit handles operating pressures up to 1.0 MPa. Note this SKU lacks a magnet, so it cannot host CMSG, DMSG, or EMSG sensors.

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 MICJ40X175-40 Is Used
Heavy Carton Diversion
Pushes heavy cartons at high speed onto a secondary line, using the 40 mm extend trim to match varying lane widths without crashing.
Vertical Flap Folding
Drives thick packaging flaps downward, relying on the adjustable air cushion to prevent impact damage at the bottom of the stroke.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ40X175-40 the Right Cylinder?
The combination of the 40 mm extend trim and dual air cushions shines in fast set-position moves where you must repeatedly hit a precise forward spot without swapping hardware. Mount via LB foot, FA flange, or TC trunnion (SDB pivot-block is not offered).
Remember the stop screw sets the end position but is not a mid-stroke lock. The cylinder will drift on air loss, and the cushions only decelerate near the stroke ends. To hold a suspended load safely, add an external rod lock or pilot check valve. Because this specific SKU has no -S magnet, position sensing is unavailable.
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 MICJ40X175-40 FAQ
This Ø40 mm bore cylinder features a 1/4" port and M12x1.25 male rod thread.
An external screw shortens the extend stroke by up to 40 mm, letting you set the forward end position. Needle valves adjust the air cushions at both ends to decelerate the piston at high speed. This base SKU lacks a magnet for sensors; you need the -S variant for CMSG, DMSG, or EMSG switches.
