Airtac MIJ Adjustable Cylinder MIJ8X20-10
The AirTAC Airtac MIJ Adjustable Cylinder MIJ8X20-10 is a genuine double acting, adjustable stroke round-body mini air cylinder with a Ø8mm bore and 20mm 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 MIJ8X20-10
Trimming the forward end by up to 10 mm on site, the AirTAC MIJ8X20-10 lets you dial in a 10 to 20 mm extend position without changing the cylinder. This double-acting, round-body stainless steel mini delivers 25.1 N of push force 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.
Built with a stainless barrel and Ø4 mm rod for mild washdown resistance, it conforms to the ISO 6432 mounting interface. The M5x0.8 port and fixed TPU bumper pads keep the package compact, while the external stop screw sets the forward end position but does not lock the piston mid-stroke.

Where the Airtac MIJ Adjustable Cylinder MIJ8X20-10 Is Used
Micro-actuation
Drives tiny push pins and light detents with a 15 N safe working load, using the stop screw to hit the exact insert depth.
Small part ejection
Flicks lightweight plastic components out of a mold cavity, fine-tuning the 10 to 20 mm extend reach to clear obstructions.
Sensor flag tripping
Extends a mechanical arm to trip an external limit switch, adjusting the forward stop to set the trigger point accurately.
Is the Airtac MIJ Adjustable Cylinder MIJ8X20-10 the Right Cylinder?
When sizing this 8 mm bore, step up to the MIJ12 if you need more force (56.5 N push at 0.5 MPa), as no smaller MIJ bore exists. The 10 mm adjustment window is perfect for taking up mechanical tolerances during setup. Remember that the piston drifts on air loss, so fit an external pilot check valve if the load must hold position. Foot, flange, and trunnion mounts apply, but the SDB pivot block is not offered. This SKU lacks a magnet, so it cannot accept CMSG, DMSG, or EMSG sensors.
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 MIJ8X20-10 FAQ
It provides 25.1 N push and 18.8 N pull at 0.5 MPa, or 35.2 N push and 26.4 N pull at 0.7 MPa. The theoretical maximum force is 5.1 kgf at 1.0 MPa. The air port is M5x0.8.
An external stop screw shortens the extend stroke by up to 10 mm, giving a usable forward range of 10 to 20 mm while retract remains full. Because this SKU lacks the -S magnet, it cannot host position sensors.
