The AirTAC MICJ Adjustable Mini Cylinder MICJ40X100-75 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.
Dial in a precise forward stop on-site with the AirTAC MICJ40X100-75, a round-body stainless-steel mini cylinder built for double-acting service. An external screw trims the extend end position by up to 75 mm (giving a usable 25-100 mm forward travel), while a needle-set air cushion at both ends absorbs high-speed shock.
This riveted stainless construction shrugs off mild corrosion and washdown environments. Note this non-magnet SKU cannot host 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. |
| ×100 | Stroke length in mm. |
| -75 | 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.
Pushes heavy palletized cartons at 800 mm/s on a packaging line, using the 75 mm extend trim to dial the exact push distance while the dual air cushions prevent end-of-stroke slamming.
Seats solid metal pins with 628.3 N of 0.5 MPa push force, relying on the adjustable forward stop to set the precise 40 mm insertion depth without swapping physical spacers.
Raises a 30 kg material lift gate safely under the 32 kg vertical lift margin, using the needle cushion to soften the high-speed arrival at the top extend position.
When sizing this 40 mm bore, compare it directly against the adjacent options. Stepping down to the 32 mm bore drops your 0.5 MPa push force to 402.2 N, whereas this 40 mm unit delivers 628.3 N; there is no larger standard MICJ bore available. Choose this model when you need substantial push power combined with on-the-fly extend shortening and high-speed cushioning.
Remember that the stop screw sets the end position but acts purely as a forward stop, not a mid-stroke lock. The piston will drift on air loss, so add an external rod lock or pilot check valve for suspended loads. Mount using LB foot, FA flange or TC trunnion (SDB pivot-block is unavailable), and select the -S magnet variant if position sensing is required.
Quick checklist
This 40 mm bore cylinder features a 1/4" port and a 16 mm rod.
An external screw shortens the extend stroke by up to 75 mm, while the needle-set air cushion decelerates the piston near stroke ends at speeds up to 800 mm/s. The cushion only slows travel and does not lock the piston; on air loss the cylinder drifts, so use an external rod lock to hold a load. This SKU lacks a magnet, so it cannot take sensors.
