Abstract
A rolling bearing apparatus is disclosed, which have a cage disposed between an inner ring raceway track and an outer ring raceway track in a freely rotatable manner so as to guide and hold a plurality of rolling elements, wherein said cage is made of a resin composition which comprises a melt-moldable fluororesin as the main component and further contains at least one solid lubricant having an average particle diameter of from 0.1 to 60 .mu.m and a fibrous filler having an aspect ratio of from 3 to 200. The rolling bearing apparatus is inexpensive and, in particular, is capable of retaining lubricity over long even in a high-temperature environment and is reduced in the outward flying of particles therefrom.
