Good bearings
Reviewed in the United States on August 27, 2025 by Don Epand

  • They spin freely and meet spec
Item Package Quantity: 10 Size: MR126-2RS 6x12x4mm
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.

  • Nice bearings in a useful size for RC cars.
Item Package Quantity: 10 Size: MR105-2RS 5x10x4mm
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.

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

  • ID not 5mm
Item Package Quantity: 10 Size: MR74-2RS 4x7x2.5mm
ID not 5mm, will not fit on a 5mm stainless rod. Took a micrometer to both, rod is 5mm, bearing is 4.94mm.
