ROLLER BEARING WITH MEANS FOR LUBRICATING THE INNER RACE

摘要

A bearing, of the type comrising an inner race and an outer race, and a plurality of rollers uniformly distributed and located between the inner and outer races, a lubricant forming a film on the outer raceway is forced to penetrate holes drilled axially into the outer race, which conduct the lubricant toward one or more passageways to apply it to the inner raceway of the bearing. The outer race of the bearing also has a plurality of holes extending obliquely to permit the recycling of the lubricant.
