Airtac MIJ Adjustable Cylinder MIJ10X40-30
The AirTAC Airtac MIJ Adjustable Cylinder MIJ10X40-30 is a genuine double acting, adjustable stroke round-body mini air cylinder with a Ø10mm bore and 40mm stroke, M5×0.8 air ports and a stainless-steel barrel and rod for mildly corrosive environments. Its ISO 6432 mounting interface makes it a compact drop-in for standard mini-cylinder fixtures.

About the Airtac MIJ Adjustable Cylinder MIJ10X40-30
Dial in a precise forward end position on the fly with this stainless steel round-body mini cylinder. A built-in external stop screw lets you shorten the extend stroke by up to 30 mm on site, turning a 40 mm nominal stroke into a highly adaptable 10 to 40 mm forward movement without swapping parts. The retract stroke remains full length, and the screw simply sets the end stop rather than acting as a mid-stroke lock.
Built to the ISO 6432 mounting interface, the Ø10 mm bore drops directly into standard mini brackets and clevises. It delivers 39.3 N of push force at 0.5 MPa, translating to a safe working load of roughly 24 N or a 2 kg vertical lift with a 2:1 safety margin. The stainless barrel and rod shrug off mild washdown environments. Note this specific SKU lacks a magnet, so it cannot host CMSG, DMSG or EMSG sensors without upgrading to the -S variant.

Where the Airtac MIJ Adjustable Cylinder MIJ10X40-30 Is Used
Light-Part Ejection
Push small plastic or aluminium components out of a machining fixture, tweaking the extend stop in 1 mm increments to clear varying part geometries without reprogramming the machine.
Staged Sorting Diverter
Divert lightweight packages on a conveyor by adjusting the forward stroke on the fly, accommodating different box widths on the same line using the 30 mm trim window.
Carton Flap Tucking
Tuck packing flaps prior to sealing, using the adjustable end position to gently push cardboard without crushing the carton, relying on the 2 kg safe lift capacity.
Is the Airtac MIJ Adjustable Cylinder MIJ10X40-30 the Right Cylinder?
When sizing this actuator, compare its 39.3 N push force at 0.5 MPa against adjacent bores: step down to an Ø8 mm MIJ for lighter 25.1 N tasks, or move up to a Ø12 mm unit if you need 56.5 N to overcome higher friction. The 30 mm adjustment window is invaluable for absorbing mechanical tolerances during setup or staging multiple feed distances from a single part number. Just remember the piston will drift and drop its load if air pressure is lost, as the stop screw and fixed TPU bumper pads decelerate the stroke end but do not function as a brake. For suspended loads, specify an external pilot check valve or rod lock. Mount via LB foot, FA flange or TC trunnion, noting the SDB pivot block is not offered for this adjustable series.
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 MIJ10X40-30 FAQ
This Ø10 mm bore cylinder features an M5x0.8 air port and a male M4x0.7 rod thread. It generates 39.3 N push and 33 N pull at 0.5 MPa, increasing to 55 N push and 46.1 N pull at 0.7 MPa. The theoretical maximum force is 8 kgf at 1.0 MPa.
An external stop screw shortens the extend stroke by up to 30 mm, allowing you to set a precise forward end position between 10 and 40 mm while the retract stroke remains full. Because this SKU lacks a magnet, it cannot support position sensors; you would need the -S variant for CMSG, DMSG or EMSG switches.
