The AirTAC MICJ Adjustable Mini Cylinder MICJ40X200-20S is a genuine double acting, double rod, adjustable stroke + cushion round-body mini air cylinder with a Ø40mm bore and 200mm 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 hardware: the MICJ40X200-20S uses an external screw to shorten the extend stroke by up to 20 mm (yielding a 180-200 mm usable forward position), while the retract remains full. This double-acting round-body mini cylinder pairs that set-position flexibility with a variable air cushion at both ends to soak up high-speed shock.
The -S suffix equips the piston with a magnet for 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).

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.
Lowers a 32 kg assembly head safely; the external screw fine-tunes the down position to prevent crushing, while the needle cushion decelerates the load near the stroke end.
Feeds heavy packaging material forward and stops precisely at 190 mm; the stainless construction resists mild washdown, and the -S magnet tracks rod position via DMSG sensors.
The adjustable stop plus needle cushions shine in fast set-position moves where you must tune both the impact and the exact end point.
Remember the stop screw sets the end position but is not a mid-stroke lock; a plain cylinder drifts on air loss, so fit an external rod lock or pilot check valve for held loads. Mount via LB foot, FA flange or TC trunnion (SDB is unavailable on this variant), and use the 1/4" port for air supply.
Quick checklist
This double-acting cylinder uses a 1/4" air port. At 0.5 MPa it pushes 628.3 N and pulls 527.8 N; at 0.7 MPa it pushes 879.6 N and pulls 738.9 N. The theoretical maximum force is 128.1 kgf at 1.0 MPa.
An external screw shortens the extend end position by up to 20 mm on-site without affecting the full retract stroke. The variable air cushion at both ends only decelerates the piston near the ends to absorb shock; it is not a mid-stroke lock or brake. The built-in -S magnet enables CMSG, DMSG and EMSG sensors.
