About the Airtac MICJ Adjustable Mini Cylinder MICJ40X25-10
Trim the forward stop by up to 10 mm on site with the AirTAC MICJ40X25-10, a stainless round-body mini cylinder built for fast, high-impact moves. The external screw sets the extend end position between 15 and 25 mm, while a needle-set variable air cushion at both ends soaks up high-speed shock.
The Ø40 bore uses a 1/4" port, a 16 mm piston rod, and an M12x1.25 male rod thread. Because this is a non-magnet SKU, it cannot host CMSG, DMSG, or EMSG sensors; you would need the -S variant for position detection. The stainless barrel and rod resist mild washdown corrosion.

| 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 MICJ40X25-10 Is Used
Heavy Clamping
Dial in the 25 mm extend stroke to clamp 30 kg metal parts securely, relying on the air cushion to absorb the impact of rapid closure.
Pallet Stopping
Halt heavy pallets on a line by adjusting the forward stop up to 10 mm, letting the dual cushions soak up the kinetic energy safely.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ40X25-10 the Right Cylinder?
The 10 mm extend adjuster plus dual air cushions are ideal when you need to dial in a precise forward stop and control impact at high speeds.
Keep in mind the stop screw only sets the end position; it is not a mid-stroke lock. The cylinder will drift and the cushion only decelerates near the stroke end, so for holding a load on air loss you must add an external rod lock or pilot check valve. Mount via LB foot, FA flange, or TC trunnion (SDB pivot-block is not available on this adjustable 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 MICJ40X25-10 FAQ
This double-acting cylinder pushes with 628.3 N and pulls with 527.8 N at 0.5 MPa. At 0.7 MPa, push is 879.6 N and pull is 738.9 N. The theoretical maximum force is 128.1 kgf at 1.0 MPa. It features a 1/4" air port and a 16 mm piston rod with an M12x1.25 male thread.
An external screw shortens the extend stroke by up to 10 mm (usable range 15-25 mm); retract remains full. Needle valves adjust the variable air cushion at both ends to decelerate high-speed impacts, but this is not a mid-stroke lock. This specific SKU lacks a magnet, so it cannot host CMSG/DMSG/EMSG sensors—you need the -S variant for sensing.
