About the Airtac MICJ Adjustable Mini Cylinder MICJ16X40-20TC
Trim the forward stop by up to 20 mm on site without swapping hardware using this stainless-steel, round-body mini cylinder. The MICJ16X40-20TC pairs that adjustable extend stroke with a needle-set air cushion at both ends, letting you dial in the exact 20 to 40 mm forward position while soaking up high-speed impact. It uses the ISO 6432 mounting interface for easy bracket drops.
The M5×0.8 port and M6x1.0 male rod thread keep the pneumatic footprint compact. Note this SKU lacks a magnet, so it cannot host CMSG, DMSG, or EMSG sensors without moving to the -S variant.

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 MICJ16X40-20TC Is Used
Micro-Clamp Actuation
Dial in a precise 25 mm clamp reach on small parts using the 20 mm extend trim, while the dual air cushions absorb the impact of fast 30-800 mm/s cycling.
Lab Dispenser Positioning
Set an exact fluid dispense height between 20 and 40 mm. The stainless barrel resists mild washdown, though you must add a pilot check valve to hold the load on air loss.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ16X40-20TC the Right Cylinder?
For lighter tasks, the MIJ bumper-only series is your only smaller step down, as the cushion build starts here at Ø16. This TC trunnion model suits pivoting loads, but remember the SDB pivot-block is not offered on adjustable-stroke builds.
The external screw sets the extend endpoint only and is not a mid-stroke lock. Because a standard cylinder drifts on air loss, add an external rod lock or pilot check valve if you must hold a suspended load. The adjustable air cushions strictly decelerate the piston near the end caps to absorb shock.
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 MICJ16X40-20TC FAQ
This 16 mm bore cylinder uses an M5×0.8 port and an M6x1.0 male rod thread. The theoretical maximum force is 20.5 kgf at 1.0 MPa.
An external screw shortens the extend stroke by up to 20 mm, setting the forward endpoint without affecting the full retract. Needle valves adjust the air cushions at both ends to decelerate the piston, but this is not a mid-stroke lock. This specific SKU has no magnet and cannot host CMSG/DMSG/EMSG sensors; choose the -S variant for sensing.
