Bearing assemblies for use in low-temperature conditions are provided. The bearing assemblies include polycrystalline diamond bearing elements having diamond bearing surfaces and opposing bearing elements having metal bearing surfaces. The metal bearing surfaces include a metal that contains at least 2 weight percent of a diamond solvent-catalyst based on a total weight of the metal. The metal is ductile at temperatures ranging from −150° C. to −253° C. The metal bearing surface is in sliding contact with the diamond bearing surface.
