The AirTAC MICJ Adjustable Mini Cylinder MICJ40X100-100 is a genuine double acting, double rod, adjustable stroke + cushion round-body mini air cylinder with a Ø40mm bore and 100mm stroke, 1/4" air ports and a stainless-steel barrel and rod for mildly corrosive environments.
Trim the forward stop by up to 100 mm on site without swapping cylinders using the AirTAC MICJ40X100-100. This double-acting round-body mini cylinder pairs that adjustable extend stroke with a needle-set variable air cushion at both ends to soak up high-speed shock, letting you dial in the exact position and control the impact.
Built with a stainless-steel barrel and piston rod, the riveted construction resists mild corrosion and handles washdown environments. Note that this SKU lacks a magnet and cannot host CMSG, DMSG or 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).

|---|---|
| 40 | Bore size in mm. |
| ×100 | Stroke length in mm. |
| -100 | 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.
Dial in the 100 mm extend stop to clamp 32 kg workpieces securely, relying on the dual air cushions to absorb the high-speed impact at the end of travel.
When sizing this 40 mm bore, stepping down to the Ø32 model drops the 0.5 MPa push force to 402.2 N, while no larger MICJ bore exists above it. The external stop screw and dual air cushions shine in fast set-position moves where you must precisely trim the extend end and decelerate smoothly without slamming. Remember the stop screw only sets the forward end position—it is not a mid-stroke lock, and 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 pivot-block is unavailable here), and choose the -S variant if you need sensing.
Quick checklist
This 40 mm bore cylinder uses a 1/4" port.
An external screw shortens the extend stroke by up to 100 mm on site, while a needle valve adjusts the variable air cushion at both ends to decelerate high-speed moves. The cylinder does not hold position on air loss and the screw is not a mid-stroke lock; use an external rod lock for holding. This non-magnet SKU cannot take sensors.
