About the Airtac MIJ Adjustable Cylinder MIJ40X60-40S
Dial in your forward end position on-site with the AirTAC MIJ40X60-40S, a round-body stainless mini cylinder featuring a 40 mm extend-stroke adjustment window. An external stop screw lets you trim the forward stroke from its 60 mm nominal length down to 20 mm, allowing one unit to cover multiple stop distances without swapping hardware. The retract stroke remains full length. Built with a stainless-steel barrel and Ø16 mm piston rod, this double-acting actuator resists mild corrosion and washdown environments.
It uses a 1/4" port and an M12x1.25 male rod thread. Because this SKU includes the -S magnet, it supports CMSG, DMSG, and EMSG position sensing. Fixed TPU bumper pads decelerate the piston at the stroke ends, operating at speeds of 30-800 mm/s across a -20 to +70 C temperature range.

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 MIJ40X60-40S Is Used
Variable Length Diverter
Route varying package sizes on a line by using the external screw to set the extend position between 20 and 60 mm, shifting product flow without changing the actuator.
Tiered Lift Gates
Lift loads up to 32 kg in distribution hubs, adjusting the forward stop on-site to create tiered lifting heights for sorting different container profiles.
Is the Airtac MIJ Adjustable Cylinder MIJ40X60-40S the Right Cylinder?
If your application exceeds this capacity, no larger standard MIJ bore exists, so you would need to explore twin-cylinder setups. The 40 mm external stop screw is ideal for taking up mechanical tolerances during setup or staging feeds across multiple points, but remember it only trims the extend end; it is not a mid-stroke lock.
This cylinder does not hold position upon air loss—the piston will drift, so add an external rod lock or pilot check valve for suspended loads. 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. Position sensing is ready out of the box via the built-in magnet for electronic or reed switches.
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 MIJ40X60-40S FAQ
The theoretical maximum force is 128.1 kgf at 1.0 MPa.
The external stop screw shortens the extend stroke by up to 40 mm on-site (usable range 20-60 mm), while retract remains full. The -S suffix denotes a built-in piston magnet for CMSG, DMSG, or EMSG sensors. Fixed TPU bumpers absorb end impacts.
