The AirTAC MICJ Adjustable Mini Cylinder MICJ40X60-30 is a genuine double acting, double rod, adjustable stroke + cushion round-body mini air cylinder with a Ø40mm bore and 60mm stroke, 1/4" air ports and a stainless-steel barrel and rod for mildly corrosive environments.
Dial in the forward stop on site without swapping cylinders: the MICJ40X60-30 uses an external screw to shorten the extend stroke by up to 30 mm, giving a usable 30-60 mm forward range while retract remains full. As a round-body stainless-steel mini cylinder, it pairs this settable position with a needle-adjustable air cushion at both ends to soak up high-speed shock.
Note this SKU lacks a magnet, so it cannot take CMSG/DMSG/EMSG sensors.

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.
| 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).
| MICJ | round-body mini cylinder (adjustable-stroke, variable cushion). |
|---|---|
| 40 | Bore size in mm. |
| ×60 | Stroke length in mm. |
| -30 | Adjustable stroke window (mm the extend stroke can be shortened on site). |
| -S | Optional built-in magnet for CMSG / DMSG / EMSG sensors. |
MI-family variants: MI / MIC (double acting ±cushion), MSI / MTI (single acting push / pull), MID / MICD (double rod ±cushion), MIJ / MICJ (double rod, adjustable stroke ±cushion). Back covers CA / U / R / CM. Mounting LB / FA / SDB / TC.
Halts pallets on a roller conveyor; the twin needle cushions decelerate the impact, while the stainless build resists mild washdown corrosion.
The adjustable stop plus twin air cushions shine in fast set-position moves, letting you trim the extend end and control impact without external shock absorbers.
The stop screw sets the end position but is not a mid-stroke lock, and the piston will drift on air loss. For a held load, use an external rod lock or pilot check valve. Mount via LB foot, FA flange or TC trunnion (SDB is unavailable here), and choose the -S variant if you need magnetic sensing.
Quick checklist
The theoretical maximum force is 128.1 kgf at 1.0 MPa.
An external screw shortens the extend stroke by up to 30 mm (retract stays full). Needle valves adjust the air cushion at both ends to decelerate the piston near stroke end. This SKU has no magnet (-S required for sensors) and the cushion only decelerates, it does not lock the load.
