Abstract

A sealed bearing assembly including an inner race, an outer race, and a plurality of balls forming therewith a bearing, a pair of closure members along the sides thereof, and a pair of identical annular seals positioned between the bearing and the closure members, is constructed such that an annular pocket is formed by the seals about the rolling elements. The seals act to confine lubricating material within the pocket to only the specific volume where it is needed. The seals not only preclude seepage of the lubricating material, but also facilitate the economical use of modern greases.
