About the Airtac MICJ Adjustable Mini Cylinder MICJ40X225-10S
Dial in a precise forward stop without swapping hardware using the AirTAC MICJ40X225-10S, a round-body stainless-steel mini cylinder that shortens the extend end position by up to 10 mm on-site. Built as a double-acting actuator with a 225 mm nominal stroke, it yields a usable extend range of 215-225 mm while retract remains full. A needle-set variable air cushion at both ends soaks up high-speed shock, letting you set the position and control the impact simultaneously.
Equipped with a 1/4" port, an M12x1.25 male rod thread, and a built-in magnet (-S), it supports CMSG, DMSG, and EMSG sensors for precise position feedback.
Airtac MICJ Adjustable Mini Cylinder MICJ40X225-10S Technical Specifications
| Model | Airtac MICJ Adjustable Mini Cylinder MICJ40X225-10S |
|---|---|
| Series | MICJ mini cylinder |
| Bore size | Ø40 mm |
| Stroke | 225 mm |
| Acting type | Double acting, double rod, adjustable stroke + cushion |
| 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 |
| Cushion | Variable air cushion, both ends |
| Max standard stroke | Up to 500 mm |
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 MICJ40X225-10S Is Used
Large Case Sealing
Handles heavy packaging flaps during automated sealing, using the needle-set cushion to prevent crushing the cardboard at high cycling speeds.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ40X225-10S the Right Cylinder?
There is no larger standard MICJ bore available, making this the top force option in the series for heavy set-position moves. The adjustable extend stop and dual air cushions are ideal for fast, high-mass cycles where you must trim the forward endpoint by up to 10 mm without mechanical rebound.
For mounting, choose LB foot, FA flange, or TC trunnion brackets, plus CA, U, R, or CM back covers (note that the SDB pivot-block is not available on this adjustable variant). The included -S magnet enables reed or electronic sensing. Remember that the stop screw sets the end position but is not a mid-stroke lock; the air cushion only decelerates near the stroke end. Because a plain cylinder does not hold its load on air loss, install an external rod lock or pilot-operated check valve if you need to prevent drift.
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 MICJ40X225-10S FAQ
This 40 mm bore cylinder features a 1/4" air port and an M12x1.25 male rod thread.
An external screw shortens the extend stroke by up to 10 mm (usable range 215-225 mm) without affecting the full retract, while the needle-set air cushion decelerates the piston near both ends to absorb shock. The -S suffix indicates a built-in piston magnet for CMSG, DMSG, or EMSG sensors. The cushion only decelerates and is not a mid-stroke lock.
