About the Airtac MICJ Adjustable Mini Cylinder MICJ40X225-20
Trim the forward stop by up to 20 mm on site without swapping cylinders using the AirTAC MICJ40X225-20. This 40 mm bore round-body mini cylinder pairs an adjustable extend stroke with a needle-set variable air cushion at both ends to soak up high-speed shock. The stainless-steel barrel and rod resist mild corrosion and washdown environments, operating at 30-800 mm/s.
This non-ISO-6432 unit features a 1/4" port, an M12x1.25 male rod thread, and a 225 mm stroke. Note this SKU lacks a magnet, so it cannot take CMSG/DMSG/EMSG sensors; choose the -S variant for position detection.

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 MICJ40X225-20 Is Used
Heavy Clamping
Dial in the 20 mm extend stop to clamp 32 kg assemblies precisely while the dual air cushions absorb the high-speed impact.
Vertical Lift Gates
Lift materials vertically and rely on the needle-set cushions to decelerate the load smoothly before the end of the stroke.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ40X225-20 the Right Cylinder?
The 20 mm extend adjuster and dual air cushions excel in fast set-position moves where you must dial in a precise forward stop and control end-of-stroke shock.
Remember the stop screw sets the end position but is not a mid-stroke lock; the piston drifts on air loss. For a held load, install an external rod lock or pilot check valve. Mount via LB foot, FA flange, or TC trunnion, as SDB pivot-blocks are unavailable here.
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 MICJ40X225-20 FAQ
The theoretical maximum is 128.1 kgf at 1.0 MPa. This 40 mm bore unit uses a 1/4" air port.
An external screw shortens the extend stroke by up to 20 mm, letting you set the forward stop between 205 and 225 mm. Needle valves adjust the air cushion at both ends to decelerate the piston. This SKU has no magnet, so it cannot take sensors; use the -S variant for CMSG/DMSG/EMSG switches.
