  • They spin freely and meet spec
Size: MR126-2RS 6x12x4mm Number of Items: 10
As far as my use cases go, these bearings are good. They spin easily and they are within the spec for the relatively large tolerances I can live with. I use them for various hobby projects, so nothing too critical.

  • False title
Size: MR115-2RS 5x11x4mm Number of Items: 10
Only comes with 10 bearings, not 20 like the title would have you believe.

  • Nice bearings in a useful size for RC cars.
I've got RC crawlers that use 5x10x4mm sized bearings. These are the right size and do what they need to on my RC trucks.
