Hezukyp CNC Set 15-1000mm 2X Linear Guideway Rail 4X Square Type Carriage Bearing Block

This product is great and quality beyond expectations. I lost my mind for a bit, the one end of the bag was opened and I lifted the rail upside down and off came the bearings and bearing balls everywhere. I put them in a ziplock and forgot about it.

great tracks if you know what to do
