About the Airtac MICJ Adjustable Mini Cylinder MICJ40X225-75S
Trimming the forward position by up to 75 mm on site, this double-acting round-body mini cylinder lets you set an exact 150-225 mm extend stop without swapping hardware. A needle-set variable air cushion at both ends soaks up high-speed shock, while the stainless-steel barrel and Ø16 rod resist mild corrosion and washdown.
Because the -S suffix includes a built-in piston magnet, you can mount CMSG, DMSG or EMSG sensors for position confirmation. The external screw sets the extend end position only and is not a mid-stroke lock; the air cushion merely decelerates near the stroke end.

| 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 MICJ40X225-75S Is Used
Heavy Carton Diversion
Pushes heavy cartons at high speed on a packaging line, using the 75 mm extend adjustment to dial in the exact push distance while the air cushion absorbs the impact at the end of the 225 mm stroke.
Washdown Part Ejection
Ejects machined stainless parts from a coolant bath, where the corrosion-resistant round-body construction survives splashing and the adjustable forward stop sets the precise drop position.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ40X225-75S the Right Cylinder?
When sizing this Ø40 bore, dropping down to the Ø32 MICJ drops the 0.5 MPa push force to 402.2 N, whereas this 628.3 N model is the largest available in the adjustable-stroke cushioned series. Choose this 225 mm unit when you need high impact energy absorbed at the end of a long, fast move, paired with on-site position tuning. The adjustable stop and cushion combination is ideal for fast set-position cycling, but remember the cylinder drifts on air loss—the stop screw is not a brake. For holding a suspended load, fit an external rod lock or pilot check valve.
Mount this stainless round-body unit using LB foot, FA flange or TC trunnion brackets; the SDB pivot block is not offered on this adjustable variant. The included magnet enables CMSG, DMSG and EMSG switches for precise end-of-stroke detection.
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 MICJ40X225-75S FAQ
This Ø40 bore double-acting cylinder uses a 1/4" air port and an M12x1.25 male rod thread.
An external screw shortens the extend stroke by up to 75 mm on site, giving a usable 150-225 mm forward position, while a needle valve adjusts the air cushion at both ends to absorb high-speed shock. The -S suffix means it has a built-in magnet for CMSG, DMSG or EMSG sensors. The stop screw sets the end position only and does not lock the load mid-stroke.
