TRB RC 8x22x7mm S-608 Open Ball Bearing Hybrid Ceramic

As the other reviewer said. There is too much play in the bearing that causes it to bind.I would look elsewhere.

$8 for 1 bearing I expected radial play to be more tight. At high speeds, shudder and skipping becomes a problem since there's too much space between the balls and races, something you'd expect to be minimal for the price.For general application where you just need something to roll, it seems fine, but for $8 you can buy 2 ceramic bearings of better quality or 4 steel bearings
