Abstract

A rolling contact bearing assembly comprises an inner race member adapted to be mounted on a rotatable element and including a spacer disposed axially adjacent the inner race. This inner race member is formed with a lubricant reservoir for accommodating a lubricant and a lubricant flow passage communicating the reservoir with a space defined between the inner and outer race, in which space rolling elements are accommodated. At least a portion of said lubricant flow passage is defined by minute interstices which are formed by surface roughness left by surface roughening at an interface between mutual contact faces of a plurality of component parts forming the inner race member.
