The AirTAC MICJ Adjustable Mini Cylinder MICJ16X40-20 is a genuine double acting, double rod, adjustable stroke + cushion round-body mini air cylinder with a Ø16mm bore and 40mm stroke, M5×0.8 air ports and a stainless-steel barrel and rod for mildly corrosive environments. Its ISO 6432 mounting interface fits standard ISO 6432 mini-cylinder mounting interfaces.
Trim the forward stop by up to 20 mm on site without swapping cylinders, and let the adjustable air cushions at both ends soak up high-speed shock. The AirTAC MICJ16X40-20 is a double-acting, round-body stainless-steel mini cylinder that merges on-the-fly extend positioning with impact control.
Built on the ISO 6432 mounting interface for Ø16 bores, this riveted stainless barrel and rod unit handles mild washdown. Note this SKU lacks a magnet, so it cannot host CMSG/DMSG/EMSG sensors. The M5×0.8 port and M6x1.0 rod thread keep the footprint standard.

Specifications follow the official AirTAC MI/MIC (ISO 6432) datasheet. Barrel & rod: stainless steel (round-body, riveted construction). Thread options: PT (blank) / G.
| Pressure | Force (both ways) |
|---|---|

| 0.7 MPa | 121 N |
| Max (@1.0 MPa) | 18 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).

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 the extend out by 15 mm to eject 5 kg plastic parts gently, relying on the air cushion to absorb the 800 mm/s impact without breaking the form.
Lower a dispense nozzle to an exact height via the stop screw; the stainless body resists chemical splashes during daily washdown routines.
For lighter duties, the MIJ bumper-only series is your sole smaller step; if you need more push, the Ø20 bore jumps to 157.0 N at 0.5 MPa. This Ø16 shines in fast, settable-position moves where the 20 mm extend trim prevents hard mechanical crashes while the needle cushions decelerate the 30-800 mm/s travel.
The stop screw sets the end position but is not a mid-stroke lock, and the piston will drift on air loss—use an external rod lock or pilot check valve for holding. Mount via LB foot, FA flange, or TC trunnion (SDB is unavailable here), and select the -S variant if you need position sensing.
Quick checklist
The theoretical max is 20.5 kgf at 1.0 MPa. This Ø16 bore uses an M5×0.8 port and a Ø6 mm rod with an M6x1.0 male thread.
An external screw shortens the extend stroke by up to 20 mm on-site, while a needle valve adjusts the air cushion at both ends to decelerate high-speed moves. The cushion only softens the end-of-stroke impact—it is not a brake. This SKU has no magnet, so it cannot take sensors; the -S version adds that capability.
