Value Pack
Great price for imported bearings. Comparable to expensive brands I have used in the past.

Smooth Motion
Used these for my CNC router build. The movement is incredibly smooth and there is no play in the bearing.

Good Quality
Solid bearings. One arrived with a tiny scratch but works fine. Overall good value for the price.
