The AirTAC MICJ Adjustable Mini Cylinder MICJ40X100-50 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 50 mm on site without swapping cylinders using the AirTAC MICJ40X100-50. This double-acting round-body mini cylinder pairs that external extend adjuster with a needle-set variable air cushion at both ends, letting you set the exact end position and soak up high-speed shock simultaneously.
Built with a stainless-steel barrel and Ø16 piston rod (M12x1.25 male thread), it resists mild corrosion and handles washdowns. It uses a 1/4" port and operates at 30-800 mm/s. Note this non-magnet SKU cannot take a sensor; the -S variant is required for CMSG/DMSG/EMSG switches.

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. |
| -50 | 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.
Uses the adjustable air cushion to absorb shock during fast 30-800 mm/s diverting motions, preventing end-cap impact on heavy product lanes.
When sizing, the smaller Ø32 bore pushes 402.2 N at 0.5 MPa, while there is no larger MICJ option above Ø40. This 628.3 N model fits applications needing substantial force where you also need to dial in a precise extend position on the fly. The external screw shortens the extend end only; retract remains the full 100 mm.
The adjustable air cushion decelerates the load near the stroke end but does not function as a mid-stroke lock or brake. If the machine loses air, the piston will drift; use an external rod lock or pilot-operated check valve for held loads. Mount via LB foot, FA flange, or TC trunnion (SDB pivot-block is not available on this adjustable variant).
Quick checklist
This Ø40 bore cylinder uses a 1/4" port.
An external screw shortens the extend stroke by up to 50 mm on site, while a needle valve adjusts the air cushion at both ends to decelerate high-speed moves. The cushion is not a brake, and the cylinder will drift on air loss; use a pilot check valve for load holding. This non-S SKU cannot take a sensor.
