Abstract

See full text

A sealing member, for sealing urea compound-containing grease enclosed in a rolling bearing, in which an elastic body deteriorates to a low extent when the rolling bearing is subjected to a high temperature and which is capable of maintaining a preferable sealing performance for a long time and excellent in reliability and durability. The sealing member used for the rolling bearing to seal grease to be enclosed in the rolling bearing includes a rubber molding which contacts the grease. The rubber molding is formed by molding a curable fluororubber composition consisting of a copolymer containing tetrafluoroethylene, propylene, and a crosslinkable monomer consisting of unsaturated fluoro-hydrocarbon, having two to four carbon atoms, in which a part of hydrogen atoms is substituted with fluorine atoms.
