Title:
BEARING GREASE
Document Type and Number:
WIPO Patent Application WO/2012/091019
Kind Code:
A1
Abstract:
Provided is bearing grease which comprises ether-containing base oil and urea thickener, and is used in an atmosphere of a fluorine compound-based refrigerant. A bearing in which the bearing grease is employed can be used for a long time without leakage of the bearing grease. In addition, in contrast with lubricant oil, since a collection system is not necessary for the bearing grease, the surrounding area of the bearing can be made compact. Therefore, the bearing grease can be easily used in vehicles and various industrial machines as energy recovery systems in which the Rankine-cycle is employed.
