Cooling-enhanced bearing assemblies, apparatuses, and motor assemblies using the same

A bearing apparatus, comprising:

• a first bearing assembly including:
• a first plurality of superhard bearing elements distributed circumferentially about an axis, each of the first plurality of superhard bearing elements having a first bearing surface;
• a first support ring extending about the axis, the first support ring carrying the first plurality of superhard bearing elements, the first support ring including at least one outer surface;
• a plurality of cooling features projecting outwardly from the at least one outer surface of the first support ring;
• and
• a second bearing assembly including:
• a second at least one superhard bearing element generally opposed to the first plurality of superhard bearing elements of the first bearing assembly;
• and
• a second support ring that carries the second at least one superhard bearing element.
