About the Airtac MIJ Adjustable Cylinder MIJ40X160-40S
Dial in a precise forward end position on-site with the AirTAC MIJ40X160-40S, a round-body stainless mini cylinder featuring a 40mm adjustable extend window. An external stop screw lets you shorten the forward stroke from its 160mm nominal length down to 120mm, absorbing setup tolerances without swapping parts. As a double-acting actuator, it delivers robust thrust while the stainless barrel and rod resist mild corrosion and washdown environments.
The 1/4" port and M12x1.25 male rod thread ensure solid pneumatic and mechanical connections. Because this SKU includes the -S magnet, it is fully ready for CMSG, DMSG, or EMSG position sensing.

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 MIJ40X160-40S Is Used
Heavy-Duty Diverter
Position large product flows on a conveyor by tuning the extend stroke up to 40mm to match varying package widths without re-engineering the station.
Staged Pallet Stop
Use the robust 32kg vertical lift capacity to halt pallets at varying staging points, adjusting the stop screw on the fly for different load depths.
Is the Airtac MIJ Adjustable Cylinder MIJ40X160-40S the Right Cylinder?
When sizing this actuator, consider the next bore down to avoid oversizing. The 40mm external stop screw is invaluable for changeover jobs or taking up mechanical tolerance, letting one part number cover several intermediate stops. Retract remains at the full 160mm, as the adjuster trims the extend end only.
Remember that the stop screw sets the end position but acts purely as a bumper stop, not a mid-stroke lock or brake. The piston will drift if air pressure drops, so install an external rod lock or pilot-operated check valve for load-holding. Mounting options include LB foot, FA flange, and TC trunnion brackets, along with CA, U, R, or CM back covers, but the SDB pivot block is 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 MIJ40X160-40S FAQ
At 0.7MPa, push is 879.6N and pull is 738.9N. The theoretical maximum force is 128.1kgf at 1.0MPa.
An external screw shortens the extend stroke by up to 40mm on-site, giving a usable forward range of 120-160mm; retract remains full stroke. The -S suffix means a piston magnet is built-in for CMSG, DMSG, or EMSG sensors, and the stainless construction resists mild corrosion.
