About the Airtac MICJ Adjustable Mini Cylinder MICJ40X60-20S
Dial in a precise 40 to 60 mm forward stop on site with the AirTAC MICJ40X60-20S, a stainless-steel round-body mini cylinder featuring a 20 mm extend-stroke adjuster. The external screw trims the extend end position without swapping hardware, while a needle-set variable air cushion at both ends soaks up high-speed shock to protect your tooling.
The built-in magnet (-S) supports CMSG, DMSG and EMSG sensors, and the stainless construction resists mild washdown corrosion.
Airtac MICJ Adjustable Mini Cylinder MICJ40X60-20S Technical Specifications
| Model | Airtac MICJ Adjustable Mini Cylinder MICJ40X60-20S |
|---|---|
| Series | MICJ mini cylinder |
| Bore size | Ø40 mm |
| Stroke | 60 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 MICJ40X60-20S Is Used
Adjustable Forming Press
Delivers 628.3 N to seat components, using the 20 mm extend stop to dial in the exact crush depth while the air cushion absorbs the high-speed impact.
Heavy Diverter Gate
Handles payloads up to 32 kg safely, trimming the extend position to align with passing cartons without over-travel shock.
Washdown Carton Sealer
Stainless barrel and rod resist mild corrosion while applying consistent sealing pressure, with the needle cushion decelerating the stroke end.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ40X60-20S the Right Cylinder?
For lighter pushes, the MICJ32 offers 402.2 N at 0.5 MPa, whereas this 40 mm bore provides 628.3 N; no larger standard MICJ bore exists. Choose this model when you need to set a fast, exact extend position and rely on the dual-end air cushion to decelerate the load smoothly. Remember the stop screw sets the end position but does not lock mid-stroke, so fit an external rod lock or pilot check valve if you must hold a load on air loss.
Mount using LB foot, FA flange or TC trunnion brackets, as the SDB pivot block is not offered on this adjustable variant. The included -S magnet enables position sensing with CMSG, DMSG or EMSG switches.
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 MICJ40X60-20S FAQ
The theoretical maximum force is 128.1 kgf at 1.0 MPa.
An external screw shortens the extend stroke by up to 20 mm on site, and a needle-set variable air cushion at both ends decelerates the piston near stroke end. The -S magnet allows CMSG, DMSG and EMSG sensors to track position.
