摘要： A rolling bearing is used for supporting a rocking mechanism or a rotating mechanism, and a film comprising a fluorine-containing polymer having a functional group(s) under a fluidizied state or a film comprising a fluorine-containing polyurethane compound under a solid state is formed on at least the track surface of the rolling bearing. Since this film does not contain ions for uniformly dispersing a thickner having non uniform particle sizes such as fluorine based grease of the prior art, breakage of the film between a rolling element and a race is not likely to occur, and wear of a rolling element race resulting from the direct contact between them due to breakage of the film can be reduced. When this film is tha same kind of a film as a protective film of the surface of an information recording disk, dust generating components of the film are the same kind of components as those of the protective film, and information recording/reproduction of the information recording disk is not impeded.
摘要翻译：滚动轴承用于支撑摆动机构或旋转机构，并且包含在流化状态下具有官能团的含氟聚合物或含有固体状态的含氟聚氨酯化合物的膜的膜是形成在至少滚动轴承的轨道表面上。由于该膜不含有用于均匀分散具有现有技术的氟系润滑脂等不均匀粒径的增稠剂的离子，因此不容易发生滚动元件与座圈之间的膜的破损，滚动体的磨损可以减少由于它们之间由于膜的断裂而直接接触而产生的种类。当该膜与信息记录盘的表面的保护膜相同的膜时，膜的尘埃产生成分与保护膜的成分相同，信息记录/再现录音盘不受阻碍。
