Ball bearing

摘要

A ball bearing has inner and outer raceways, and a row of balls mounted to roll between said raceways. The outer raceway is defined by an outer ring axially held in position by flanges of an outer sleeve. An axially extending space is provided between the outer ring and one of the flanges of the outer sleeve, for receiving a bearing element determined by the use in which the bearing will be placed. Examples of the bearing function-defining element are an annular seal, a corrugated annular spring, and the combination of a corrugated annular spring and a rigid washer.
