Abstract
Bearing grease includes an ether base oil and a urea thickener, and is used in an atmosphere of a fluorine compound-based refrigerant. No grease is eluted for a long period in a bearing with use of the bearing grease. Moreover, since a collection system is unnecessary unlike a lubricating oil, the surroundings of the bearing can be made compact. Accordingly, the bearing with use of the bearing grease is easily applicable to automobiles and a variety of industrial machinery as an energy collection apparatus using the Rankine cycle.
