Claims18
An assembly comprising:
- a bearing assembly including a support structure and at least one superhard bearing element including polycrystalline diamond table having a bearing surface, the polycrystalline diamond table being at least partially leached to remove a catalyst material from interstitial regions of the polycrystalline table, the bearing surface having an at least partially polished surface finish that exhibits an Ra surface finish of about 0.0025 μm or less, the at least one superhard bearing element secured to the support structure;
- and
- at least one packaging material adjacent to the support structure and the at least one superhard bearing element, the at least one packaging material configured to protect the at least partially polished surface finish of the at least one superhard bearing element.
