About the Airtac MIJ Adjustable Cylinder MIJ8X80-75
Trimming the forward end by up to 75 mm via an external stop screw, this double-acting mini cylinder lets you dial in the exact extend position from 5 to 80 mm without swapping parts. It delivers a push force of 25.1 N and a pull force of 18.8 N at 0.5 MPa, yielding a safe working load of roughly 15 N or a 1.3 kg vertical lift with a 2:1 margin. The retract stroke remains full length.
Built with a stainless-steel round barrel and piston rod, the riveted construction resists mild corrosion and washdown environments. It conforms to the ISO 6432 mounting interface for standard mini brackets, uses an M5x0.8 air port, and relies on fixed TPU bumper pads for end-of-stroke deceleration. Note this SKU lacks a magnet, so it cannot accept CMSG, DMSG, or EMSG sensors.

Where the Airtac MIJ Adjustable Cylinder MIJ8X80-75 Is Used
Micro-actuation stops
Ideal for dialing in the exact forward position of small grippers or probes, using the 75 mm adjustment window to compensate for tooling tolerances within a 15 N load limit.
Lightdiverter setup
Fine-tune the extend distance of a lightweight sorting flap on a conveyor, adjusting the stop on-site without needing multiple cylinder part numbers.
Lab test positioning
Set precise end stops for repetitive testing strokes in laboratory equipment where a 1.3 kg vertical lift capacity and stainless washdown resistance are required.
Is the Airtac MIJ Adjustable Cylinder MIJ8X80-75 the Right Cylinder?
When sizing this 8 mm bore, moving down is not an option as it is the smallest available. Stepping up to a 16 mm bore increases the 0.5 MPa push force to 100.5 N if your application outgrows the 15 N safe working load of this unit. The 75 mm adjustment window is ideal for taking up mechanical tolerances or staging feeds during setup. For load holding, remember the piston will drift on air loss; the stop screw sets the end position but is not a mid-stroke lock, so add an external pilot check valve if you need to hold a load. Mounting options include LB foot, FA flange, and TC trunnion, but SDB pivot blocks are not available for this adjustable type.
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 MIJ8X80-75 FAQ
This cylinder uses an M5x0.8 air port. At 0.5 MPa it provides 25.1 N push and 18.8 N pull; at 0.7 MPa it provides 35.2 N push and 26.4 N pull. The theoretical maximum force is 5.1 kgf at 1.0 MPa.
An external stop screw shortens the extend stroke by up to 75 mm on-site, giving a usable extend range of 5-80 mm, while the retract stroke remains full. This specific SKU does not have a magnet and cannot take CMSG, DMSG, or EMSG sensors; you would need the -S variant for sensing.
