About the Airtac MICJ Adjustable Mini Cylinder MICJ40X80-75S
Dial in the forward stop on site without swapping hardware: the MICJ40X80-75S uses an external screw to shorten the extend stroke by up to 75 mm, yielding a usable 5-80 mm forward travel while retract remains full. The adjustable air cushion at both ends soaks up high-speed shock, letting you set the position and control the impact simultaneously.
This double-acting round-body mini cylinder features a stainless-steel barrel and rod for mild washdown resistance. It includes a built-in magnet (-S) for CMSG, DMSG, or EMSG sensors, uses a 1/4" port, and operates at speeds of 30-800 mm/s.

| 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 |

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 MICJ40X80-75S Is Used
High-Speed Diverting
Divert heavier payloads on a line at up to 800 mm/s, relying on the dual adjustable air cushions to absorb shock and prevent end-cap banging.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ40X80-75S the Right Cylinder?
When sizing this 40 mm bore, stepping down to the MICJ32 drops the 0.5 MPa push force to 402.2 N, while no larger standard MICJ bore exists above it. Choose this model when you need fast set-position moves where the adjustable stop and dual cushions shine. The external screw sets the end position but is not a mid-stroke lock; the piston will drift on air loss, so add an external rod lock or pilot check valve for held loads. Mount via LB foot, FA flange, or TC trunnion (SDB is unavailable), and match the -S magnet with CMSG/DMSG/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 MICJ40X80-75S FAQ
The air port is 1/4".
An external screw shortens the extend stroke by up to 75 mm (usable 5-80 mm); retract stays full. Needle valves adjust the air cushion at both ends to decelerate the piston near stroke end, though it is not a brake. The -S magnet allows CMSG, DMSG, or EMSG switches.
