About the Airtac MIJ Adjustable Cylinder MIJ40X160-30S
Dial in your forward end position on-site with the MIJ40X160-30S, a round-body stainless mini cylinder featuring a 30 mm external stop-screw adjustment window. This double-acting actuator lets you trim the extend stroke from 160 mm down to 130 mm without swapping parts, while retract remains full length. The stainless-steel barrel and Ø16 mm piston rod supply mild corrosion and washdown resistance.
It uses a 1/4" port and an M12x1.25 male rod thread. Equipped with fixed TPU bumper pads to decelerate the stroke end, the -S suffix indicates a built-in piston magnet for CMSG, DMSG, or EMSG sensors.

Specifications follow the official AirTAC MI/MIC (ISO 6432) datasheet. Barrel & rod: stainless steel (round-body, riveted construction). Thread options: PT (blank) / G. Note: the Ø40 bore is a larger, non-ISO-6432 size.
Theoretical Output Force (Ø40mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 528 N |
| 0.7 MPa | 739 N |
| Max (@1.0 MPa) | 108 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 MIJ40X160-30S Is Used
Variable Stroke Press
Apply precise clamping pressure on cartons of different heights, adjusting the forward stop from 130 to 160 mm while relying on the 32 kg vertical lift margin.
Is the Airtac MIJ Adjustable Cylinder MIJ40X160-30S the Right Cylinder?
The 30 mm external adjuster is ideal for taking up mechanical tolerances during setup or covering multiple stop positions with a single part number. Note that the stop screw only sets the extend end position; it is not a mid-stroke lock. The piston will drift on air loss, so install an external rod lock or pilot check valve for held loads. Mount using LB foot, FA flange, or TC trunnion brackets (SDB pivot blocks are not available on this adjustable variant).
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 MIJ40X160-30S FAQ
This Ø40 mm cylinder uses a 1/4" air port. The theoretical maximum force is 128.1 kgf at 1.0 MPa.
An external stop screw shortens the extend stroke by up to 30 mm on-site, yielding a usable forward range of 130-160 mm; retract remains full stroke. The -S suffix means a magnet is built-in for CMSG, DMSG, or EMSG sensors. Fixed TPU bumpers decelerate the ends.
