About the Airtac MICJ Adjustable Mini Cylinder MICJ16X45-20S
Trim the forward stop by up to 20 mm on site without swapping cylinders using the AirTAC MICJ16X45-20S. This double-acting, round-body stainless-steel mini cylinder pairs that adjustable extend stroke with an adjustable air cushion at both ends, letting you dial in the exact forward position while soaking up high-speed shock. The built-in piston magnet (-S) directly supports CMSG, DMSG, and EMSG sensors for position confirmation.
The Ø16 mm bore uses an M5×0.8 port and conforms to the ISO 6432 mounting interface for standard mini brackets. The external screw sets the extend end position only; it is not a mid-stroke lock, and the cylinder will drift on air loss unless paired with an external rod lock or pilot check valve.

Specifications follow the official AirTAC MI/MIC (ISO 6432) datasheet. Barrel & rod: stainless steel (round-body, riveted construction). Thread options: PT (blank) / G.
Theoretical Output Force (Ø16mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 86 N |
| 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).

Where the Airtac MICJ Adjustable Mini Cylinder MICJ16X45-20S Is Used
Precision Feeder Stops
Dial the extend stroke in 1 mm increments to act as a hard stop for 5 kg sheet metal blanks, relying on the dual air cushions to absorb the impact of high-speed 30-800 mm/s operations.
Washdown Sorting
Leverage the stainless-steel barrel and rod for mild washdown resistance while using the integrated magnet to trigger DMSG sensors for confirming part ejection.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ16X45-20S the Right Cylinder?
For lighter duty, the MIJ bumper-only series is the next step down, as the cushioned MICJ line starts at this Ø16 bore. If your application requires more push force, stepping up to the Ø20 bore raises the 0.5 MPa push output from 100.5 N to 157.0 N. Choose this 45 mm stroke model when you need fast, settable-position moves within a 25 to 45 mm usable extend window.
The adjustable stop and needle-set cushions excel in high-speed scenarios where controlling the impact is critical. Mount via LB foot, FA flange, or TC trunnion (SDB pivot-block is unavailable on this adjustable variant). Because this SKU includes the -S magnet, it is fully ready for CMSG, DMSG, or EMSG switches; a non-S SKU cannot accept a sensor.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G)
- ✓ Magnet (-S) for sensors?
- ✓ Back cover (CA/U/R/CM) & mount (LB/FA/SDB/TC)
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Do not dismantle the riveted front/back covers.
- check Use correct back cover (CA/U/R/CM) & mount (LB/FA/SDB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac MICJ Adjustable Mini Cylinder MICJ16X45-20S FAQ
The theoretical maximum force is 20.5 kgf at 1.0 MPa.
An external screw shortens the extend stroke by up to 20 mm (usable extend 25-45 mm), while the needle-set adjustable air cushion at both ends decelerates the piston near stroke ends to absorb high-speed shock. The stop screw is not a mid-stroke lock, and the cylinder will drift on air loss—use an external rod lock or pilot check valve to hold a suspended load.
