About the Airtac MIJ Adjustable Cylinder MIJ16X45-20S
Trimming the forward end by up to 20 mm on site, the AirTAC MIJ16X45-20S lets you dial in a precise 25 to 45 mm extend position without changing the cylinder. This double-acting, round-body stainless steel mini cylinder conforms to the ISO 6432 mounting interface, dropping directly into standard mini brackets and clevises.
The riveted stainless barrel and rod resist mild corrosion and washdown. Fitted with a piston magnet, this -S SKU supports CMSG, DMSG and EMSG sensors, while fixed TPU bumper pads decelerate the stroke ends.

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 MIJ Adjustable Cylinder MIJ16X45-20S Is Used
Adjustable Stop Gauging
Dial in the exact 25-45 mm extend position to push a part against a gauge, absorbing mechanical setup tolerances without re machining fixtures.
Tool Changeover Stop
Set intermediate forward stops for machine tool changeovers, using the external nut to fine-tune the endpoint rather than swapping entire actuators.
Is the Airtac MIJ Adjustable Cylinder MIJ16X45-20S the Right Cylinder?
The external stop screw is ideal for taking up setup tolerances or staging feeds, allowing one part number to cover several intermediate stops. Note that the screw only sets the extend endpoint; it is not a mid-stroke lock.
This cylinder drifts on air loss, so add an external rod lock or pilot check valve to hold a suspended load. Mount using LB foot, FA flange or TC trunnion brackets, or CA, U, R and CM back covers, as the SDB pivot block is unavailable for this adjustable variant. The M5×0.8 port and M6x1.0 male rod thread match standard mini fittings.
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 MIJ Adjustable Cylinder MIJ16X45-20S FAQ
The air port is M5×0.8.
An external screw shortens the extend stroke by up to 20 mm on site, while retract remains full. The -S suffix indicates a built-in piston magnet for CMSG, DMSG or EMSG sensors. Fixed TPU bumpers decelerate the ends, but the screw is not a mid-stroke lock.
