About the Airtac MIJ Adjustable Cylinder MIJ16X40-30S
Dial in your forward end position on-site with the AirTAC MIJ16X40-30S, a double-acting round-body mini cylinder featuring an external stop screw that shortens the extend stroke by up to 30 mm. Because this is an -S variant, the built-in piston magnet supports CMSG, DMSG, and EMSG position switches.
The Ø16 bore uses an M5×0.8 port and a Ø6 mm rod with an M6×1.0 male thread. It conforms to the ISO 6432 mounting interface for standard mini brackets. Fixed TPU bumper pads decelerate the stroke end, operating at speeds from 30 to 800 mm/s.

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 MIJ16X40-30S Is Used
Adjustable Stop Gauging
Set precise forward stops for a 5.1 kg vertical lift task, using the 30 mm extend adjustment to dial in the exact contact position without swapping hardware.
Tolerance Take-Up Jig
Absorb mechanical variations in a clamping jig by trimming the extend stroke on-site, ensuring consistent 100.5 N clamping force at 0.5 MPa.
Is the Airtac MIJ Adjustable Cylinder MIJ16X40-30S the Right Cylinder?
The 30 mm adjustment window is ideal for taking up mechanical tolerances during setup or covering multiple stop positions from a single part number. Remember that the stop screw only trims the extend end; retract remains full.
This model includes the -S magnet for CMSG, DMSG, or EMSG sensors. You can use LB foot, FA flange, or TC trunnion mounts, plus CA, U, R, or CM back covers, but the SDB pivot block is not available on this adjustable variant. Note that a standard cylinder does not hold position on air loss—the piston will drift. For load holding, install an external rod lock or pilot check valve, as the stop screw and bumpers only manage the end position.
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 MIJ16X40-30S FAQ
The theoretical maximum force is 20.5 kgf at 1.0 MPa.
An external stop screw shortens the extend stroke by up to 30 mm, letting you set the forward end position without changing the cylinder; retract remains full. The -S suffix means it has a built-in magnet for CMSG, DMSG, or EMSG sensors.
