About the Airtac MIJ Adjustable Cylinder MIJ8X80-20
Dial in a precise forward end position on-site with the AirTAC MIJ8X80-20, a round-body stainless steel mini cylinder that lets you shorten the extend stroke by up to 20 mm via an external stop screw. This double-acting actuator drops directly into standard mini brackets and clevises using the ISO 6432 mounting interface, giving you a usable extend range of 60-80 mm without changing the part number.
Built with a stainless barrel and Ø4 mm rod for mild corrosion resistance, it delivers a push force of 25.1 N at 0.5 MPa. This translates to a safe working load of about 15 N, or roughly 1.3 kg of vertical lift with a 2:1 safety margin. The M5x0.8 port and fixed TPU bumper pads keep operations smooth, though note this specific SKU lacks a magnet and cannot host CMSG/DMSG/EMSG sensors.

Where the Airtac MIJ Adjustable Cylinder MIJ8X80-20 Is Used
Micro-Clamp Tolerance Take-Up
Use the 20 mm extend adjustment to dial in the exact clamping reach on delicate electronic components, absorbing fixture tolerances without swapping cylinders.
Small Part Diverting
Fine-tune the pusher stroke to deflect lightweight plastic parts on a conveyor, ensuring they seat properly into a packaging chute without crushing.
Staged Pick-and-Place
Set a specific intermediate extend position for a 1.3 kg vertical lift task, allowing one actuator to handle changeover jobs for slightly different product heights.
Is the Airtac MIJ Adjustable Cylinder MIJ8X80-20 the Right Cylinder?
When sizing this 8 mm bore actuator, verify your payload against the 25.1 N push force at 0.5 MPa. If your application requires more thrust, stepping up to the MIJ16 bore provides 100.5 N, but if you need finer miniature handling, this is the smallest available option in the range. The 20 mm adjustment window is perfect for taking up mechanical tolerances during setup or staging feeds.
Keep in mind the external stop screw only trims the extend end position; it is not a mid-stroke lock, and the piston will drift if air pressure is lost. For load holding, you must add an external rod lock or pilot check valve. Mounting options include LB foot, FA flange, and TC trunnion (the SDB pivot block is not offered 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 MIJ8X80-20 FAQ
This 8 mm bore cylinder features an M5x0.8 port and delivers a push force of 25.1 N and a pull force of 18.8 N at 0.5 MPa. At 0.7 MPa, push is 35.2 N and pull is 26.4 N. The theoretical maximum force is 5.1 kgf at 1.0 MPa.
An external stop screw shortens the extend stroke by up to 20 mm on-site, giving a usable forward range of 60-80 mm; the retract stroke remains full. This SKU does not include a magnet, so it cannot support CMSG/DMSG/EMSG sensors. You would need the -S variant for position sensing.
