Exactly what I need for my extruder. That .

Exactly what I need for my extruder. These aren't high speed bearings, but the extruder doesn't need them. I made washers for them on the tweet so they don't stick when screwed in.

Pros
  • Inner diameter: 4mm
Cons
  • Long shipping

Look out for deep groove ball bearings

Bearings were simply never designed for use in high speed drone motors and would quickly fail. However, if the bearings had been used as intended by the manufacturer I am sure they would have been satisfactory. I believe drone motors may require tighter tolerances as well as stronger housings. It was fun trying though. Cheers and good luck, comrades

Pros
  • Thickness: 4mm
Cons
  • Only available in black
