Brand new ball bearings in original packaging. Priced per bearing.

Ball bearings provide the lowest friction for rotating shafts. Tight-tolerance hardened steel balls within the bearing roll between the inner and outer "race", inside a half-round groove. This mechanism provides low friction, and long lifetime.

Thease bearings are filled with lubricant, and permanently sealed with a steel disk to keep out dust and debris. This is referred to as "shielded".
