Claims20
A bearing assembly, comprising:
- a support ring;
- a plurality of superhard bearing elements mounted on the support ring, each of the plurality of superhard bearing elements including a superhard bearing surface;
- and
- one or more lubricant bodies each of which includes graphite and are moveable relative to the superhard bearing surfaces of the plurality of superhard bearing elements, each of the one or more lubricant bodies including a lubrication surface.
