About the Airtac MICJ Adjustable Mini Cylinder MICJ40X225-100S
Dial in a precise forward stop on-site with the AirTAC MICJ40X225-100S, a round-body stainless-steel mini cylinder featuring a 100mm adjustable extend stroke. An external screw trims the forward end position down from the 225mm nominal maximum, letting you set the exact reach without swapping hardware. Retract remains full stroke. A needle-set variable air cushion at both ends soaks up high-speed shock to protect your tooling.
Built with a stainless-steel barrel and Ø16 piston rod, this double-acting unit resists mild corrosion and washdown environments. The integrated -S magnet enables position sensing with CMSG, DMSG, or EMSG switches.

| 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 MICJ40X225-100S Is Used
Pallet Diverter
Shifts loads weighing up to 32kg on a packaging line, relying on the tuned extend stop and needle-adjustable cushion to halt the 225mm stroke smoothly at high speed.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ40X225-100S the Right Cylinder?
When sizing this 40mm bore, step down to the Ø32 model if you need less push (402.2N at 0.5MPa), as there is no larger MICJ bore available. The adjustable stop screw paired with the dual air cushions is ideal for fast, repetitive set-position moves where you must tune both the end point and the deceleration rate. The -S magnet allows direct mounting of CMSG, DMSG, or EMSG sensors.
Mount using LB foot, FA flange, or TC trunnion brackets; note the SDB pivot-block is not offered on this adjustable variant. Remember that the stop screw sets the end position but is not a mid-stroke lock. Because a standard cylinder drifts on air loss, install an external rod lock or pilot-operated check valve if you need to hold a suspended load safely.
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 MICJ40X225-100S FAQ
This double-acting cylinder uses a 1/4" air port and an M12x1.25 male rod thread. The theoretical maximum force is 128.1kgf at 1.0MPa.
An external screw shortens the extend stroke by up to 100mm on-site, giving a usable forward range of 125-225mm; retract remains full. Needle valves adjust the air cushion at both ends to decelerate the piston near the ends. The cylinder does not hold position on air loss, so use an external rod lock for suspended loads. The -S magnet enables CMSG, DMSG, and EMSG sensors.
