About the Airtac MICJ Adjustable Mini Cylinder MICJ40X225-75
Dial in a precise forward stop on-site with the AirTAC MICJ40X225-75, a double-acting round-body stainless steel mini cylinder featuring a 75 mm adjustable extend stroke. An external stop screw lets you trim the forward end position down from the 225 mm nominal maximum, while a needle-set variable air cushion at both ends soaks up high-speed shock. The stainless barrel and rod resist mild corrosion and washdown environments.
This non-ISO-6432 unit uses a 1/4" port and an M12x1.25 male rod thread. Because it lacks the -S magnet option, this SKU cannot accept CMSG, DMSG, or EMSG sensors. The adjustable air cushion only decelerates the piston near the stroke end; it is not a mid-stroke lock or brake.

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 MICJ40X225-75 Is Used
Washdown Sealing Press
Performs repeatable press-downs in a damp environment thanks to the stainless construction, trimming the extend stroke on-site to accommodate varying package heights.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ40X225-75 the Right Cylinder?
When sizing this 40 mm bore, stepping down to the MICJ32 drops the 0.5 MPa push force to 402.2 N, while no larger MICJ bore exists. Choose this 225 mm stroke model when you need a long reach but must fine-tune the extend end within a 150-225 mm window without swapping cylinders. The combination of the external stop screw and dual adjustable cushions is perfect for fast, settable-position moves. Remember that the stop screw sets the end position but does not lock the piston mid-stroke. If your application must hold a load on air loss, install an external rod lock or pilot-operated check valve, as the piston will drift. Mount using LB foot, FA flange, or TC trunnion brackets; the SDB pivot-block is not available on this adjustable-stroke 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 MICJ40X225-75 FAQ
This 40 mm bore cylinder uses a 1/4" port. The theoretical maximum force is 128.1 kgf at 1.0 MPa.
An external screw shortens the extend stroke by up to 75 mm on-site, while the needle-set air cushions at both ends decelerate the piston at high speed. This specific SKU lacks a magnet, so it cannot take CMSG/DMSG/EMSG sensors. The cushion only decelerates near the end; it is not a mid-stroke lock.
