About the Airtac MICJ Adjustable Mini Cylinder MICJ40X25-10S
Shave the forward stop by up to 10 mm on site with the AirTAC MICJ40X25-10S, a round-body stainless mini cylinder built for double-acting service. The external screw trims the extend end position only, letting you dial in a 15 to 25 mm forward travel without swapping hardware, while the retract stroke remains full. A needle-set variable air cushion at both ends soaks up high-speed shock to protect your tooling.
The stainless steel barrel and rod resist mild corrosion and washdown environments. Because this SKU carries the -S suffix, it includes a built-in piston magnet for direct mounting of CMSG, DMSG, or EMSG sensors. Note that Ø40 is a non-ISO-6432 size, so it functions strictly as a heavy-duty round-body mini cylinder rather than a standard interface unit.

| Stroke | 25 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 |

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 MICJ40X25-10S Is Used
Press Fit Tooling
Dial in a precise 22 mm extend stroke to seat small bearings, using the dual air cushions to absorb the 628.3 N impact at high cycle speeds.
Heavy Diverter Gate
Lift or push a 30 kg package routing gate safely, relying on the 1/4" port and robust 16 mm rod to handle the dynamic load.
Washdown Carton Stop
Deploy the stainless steel body in damp packaging lines, adjusting the forward stop by 10 mm to catch varying carton depths without retooling.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ40X25-10S the Right Cylinder?
If you need less force, dropping down to the Ø32 bore drops the 0.5 MPa push to 402.2 N, while no larger standard round-body mini exists above Ø40 in this series. The adjustable stop and dual cushions shine in fast set-position moves where you must repeatedly hit a precise forward spot and decelerate smoothly.
Mounting options include LB foot, FA flange, and TC trunnion brackets, but the SDB pivot-block is not available on this adjustable-stroke variant. Remember that the stop screw sets the end position and the cushion only decelerates the piston near stroke end; neither acts as a mid-stroke lock. If your application must hold a load vertically during air loss, add an external rod lock or pilot-operated check valve.
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 MICJ40X25-10S FAQ
This Ø40 bore cylinder features a 1/4" air port and a 16 mm rod.
An external stop screw shortens the extend stroke by up to 10 mm on site, giving a usable 15 to 25 mm forward travel, while the retract remains full. Needle-set variable air cushions at both ends decelerate the piston near the stroke ends to absorb shock. The -S suffix means it has a built-in magnet for CMSG, DMSG, or EMSG sensors.
