About the Airtac MICJ Adjustable Mini Cylinder MICJ40X80-10S
Trim the forward stop by up to 10 mm on site without swapping cylinders using the AirTAC MICJ40X80-10S. This 40 mm bore round-body stainless-steel mini cylinder pairs an external extend adjuster with a needle-set variable air cushion at both ends, letting you dial in the exact 70-80 mm forward position while soaking up high-speed shock. The stainless barrel and rod resist mild corrosion and washdown environments.
The built-in magnet (-S) supports CMSG, DMSG and EMSG sensors for position tracking.

| Stroke | 80 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 |

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 MICJ40X80-10S Is Used
Heavy Clamping Press
Dial in the exact 70-80 mm clamp reach and use the dual air cushions to absorb impact when securing heavy 32 kg metal parts at high speed.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ40X80-10S the Right Cylinder?
The 10 mm extend trim and dual air cushions excel in fast set-position moves where you must precisely tune the forward stop and decelerate heavy loads smoothly. Choose LB foot, FA flange or TC trunnion mounts, as the SDB pivot-block is not offered on this adjustable variant.
Remember that the air cushion only decelerates near the stroke end and the stop screw sets the end position, neither acts as a mid-stroke lock. The piston will drift on air loss, so fit an external rod lock or pilot check valve if you need to hold a suspended load.
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 MICJ40X80-10S FAQ
The theoretical maximum force is 128.1 kgf at 1.0 MPa. This 40 mm bore round-body mini cylinder uses 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 on site, while a needle-set variable air cushion at both ends decelerates the piston near the ends to absorb high-speed shock. The -S magnet enables CMSG, DMSG and EMSG sensors. The cushion only decelerates and is not a mid-stroke lock, so the piston drifts on air loss; use an external rod lock for holding.
