8. The bearing support of claim 7, wherein said first surface is oriented to direct a bearing toward said bearing receiving area.

9. The bearing support of claim 1, wherein said first open end is spaced from said bearing receiving area and comprises a first surface that is sloped.

10. The bearing support of claim 9, wherein a slope of said first surface is oriented to direct a bearing toward said bearing receiving area.

11. The bearing support of claim 9, wherein said first surface is inwardly sloped in progressing toward said bearing receiving area from said first open end.

12. The bearing support of claim 1, wherein said bearing slot is located between said pair of projections.

13. The bearing support of claim 1, wherein said bearing support further comprises a perimeter surface that defines a boundary of said bearing receiving area, wherein said perimeter surface comprises an interior surface of each said projection of said pair of projections, and wherein said bearing slot is located on a portion of said perimeter surface that extends between said pair of projections.

14. A bearing assembly comprising a bearing and the bearing support of claim 1, wherein only a lower portion of said bearing is disposed in said bearing slot such an upper portion of said bearing is disposed outside of said bearing slot.

15. The bearing assembly of claim 14, wherein said bearing support further comprises a ledge, wherein a back side of said upper portion of said bearing is disposed against said ledge, and wherein said ledge precludes said bearing from being directed into said bearing receiving area through said second open end.

16. The bearing assembly of claim 1, wherein said bearing support further comprises a mounting post, wherein said pair of projections extend from one side of said base and said mounting post extends from an opposite side of said base.

17. A centrifuge system, comprising:

a frame;

a centrifuge bowl interconnected and rotatable in conjunction with said frame;

a tube extending from said centrifuge bowl; and

a first bearing, wherein said tube extends through said first bearing, and wherein said first bearing is disposed within said bearing receiving area of the bearing support of claim 1, and wherein the bearing support is mounted to said frame.
