About the Airtac MICJ Adjustable Mini Cylinder MICJ40X75-30
Dial in a precise forward stop on-site with the AirTAC MICJ40X75-30, a round-body stainless steel mini cylinder featuring a 30mm extend-stroke adjuster. The external screw trims the forward end position down from the 75mm nominal maximum, letting you set exact reach without swapping hardware. A needle-adjustable air cushion at both ends absorbs high-speed shock to protect your tooling.
Note this SKU lacks a magnet, so it cannot host CMSG/DMSG/EMSG sensors.

| Stroke | 75 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 MICJ40X75-30 Is Used
Heavy Clamping Station
Securely clamps thick metal billets. The 30mm extend adjuster dials in the exact grip depth, while the air cushion prevents shock when moving heavy parts at high speed.
Package Divert Arm
Pushes heavy cartons off a main line.
Pallet Positioning Stop
Halts loaded pallets at a wrapping station. The adjustable forward stop sets the precise halt point, and the dual cushions absorb the impact of 32kg loads arriving fast.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ40X75-30 the Right Cylinder?
Choose this 40mm bore when your fast, settable-position moves need substantial push power. The adjustable stop screw sets the extend endpoint only—it 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 using LB foot, FA flange, or TC trunnion brackets (SDB pivot-block is not offered on adjustable-stroke types). Because this specific code has no -S suffix, it cannot accept position sensors; order the -S variant if you require 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 MICJ40X75-30 FAQ
This double-acting bore 40 cylinder uses a 1/4" port and M12x1.25 male rod thread. The theoretical maximum force is 128.1 kgf at 1.0 MPa.
An external screw shortens the extend stroke by up to 30mm on-site, giving a usable forward range of 45-75mm; retract remains full stroke. Needle valves adjust the air cushion at both ends to decelerate the piston near the ends, but this is not a mid-stroke lock. The piston drifts on air loss, so use an external rod lock for holding. This non-S SKU has no magnet and cannot take sensors.
