A bearing configured for a machine in which at least part of said bearing will be subjected to a temperature of at least 150° C. during use of said machine, said bearing comprising:

• a bearing outer ring and a bearing inner ring,
• rolling elements disposed between the bearing outer ring and the bearing inner ring,
• a high temperature-resistant lubricating grease comprising a thickener and synthetic base oil, said high temperature-resistant lubricating grease having a dropping point of at least 250° C. and an NLGI consistency grade of 1.0 to 1.5, and
• at least one high temperature-resistant seal,
• wherein:
• the high temperature-resistant lubricating grease fills 50-95% of a sealed space defined, at least in part, by the bearing outer ring, the bearing inner ring and the at least one high temperature-resistant seal, and
• the rolling elements are disposed within the sealed space.
