About the Airtac MICJ Adjustable Mini Cylinder MICJ16X45-20
Dial in the forward stop on site without swapping cylinders: the AirTAC MICJ16X45-20 uses an external screw to shorten the extend end by up to 20 mm, giving a usable forward range of 25-45 mm. The retract stroke remains full length. An adjustable air cushion at both ends soaks up high-speed shock so you set the position and control the impact.
Built as a stainless-steel, riveted round-body mini cylinder, it resists mild corrosion and washdown. Note this SKU lacks a magnet, so it cannot take CMSG/DMSG/EMSG sensors; the M5×0.8 port matches the Ø16 bore.

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) |
|---|---|

| 0.7 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 MICJ16X45-20 Is Used
Precision Parts Clamping
Clamps small machined parts securely, using the 20 mm extend adjustment to dial in the exact forward stop without shimming.
Light Diverter Gate
Diverts lightweight packages on a conveyor, relying on the dual air cushions to absorb shock during fast 800 mm/s cycling.
Lab Sample Indexing
Indexes sample trays in washdown lab equipment, where the stainless barrel resists mild corrosion and the stop sets the pitch.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ16X45-20 the Right Cylinder?
Size both ways: the larger Ø20 bore raises push to 157.0 N at 0.5 MPa, while the smaller Ø12 falls outside this cushioned MICJ family and requires the bumper-only MIJ. The Ø16 fits tight spaces when you need settable position moves at speed. The external stop screw sets the extend end position but is not a mid-stroke lock; the cylinder drifts on air loss, so add an external rod lock or pilot check valve to hold a load. Mount via LB foot, FA flange, or TC trunnion (SDB pivot-block is not available), and select the -S variant if you need sensing.
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 MICJ16X45-20 FAQ
This double-acting cylinder pushes 100.5 N and pulls 86.4 N at 0.5 MPa. At 0.7 MPa it pushes 140.7 N and pulls 120.9 N. The theoretical max force is 20.5 kgf at 1.0 MPa, and the air port is M5×0.8.
An external screw shortens the extend stroke by up to 20 mm on site, while a needle-set adjustable air cushion at both ends decelerates the piston near stroke end to reduce shock. The cushion only decelerates and the screw sets the end position; neither acts as a mid-stroke lock, so the piston drifts on air loss. This non-S SKU lacks a magnet for sensors.
