Abstract

A roller bearing assembly is disclosed which has a single-piece outer race ring having a central, circumferential depression and a pair of raceway surfaces on opposite sides thereof. An inner race ring, sized and shaped to fit within the outer race ring, comprises a pair of inner race members. Each of the inner race members has two ends and a raceway surface formed at least in part by a shoulder. The inner race members are positioned so as to abut each other at their respective abutting ends and are axially aligned such that the raceway surfaces of the inner race members are aligned with one of the raceway surfaces of the outer race ring to form two raceways. A substantially tubularly-shaped inner sleeve having two ends is disposed in the internal bore of the inner race ring for maintaining the axial alignment of the inner race members. The inner sleeve has stop members, in the form of flared ends, which cooperate with the shoulders of each of the inner race members to desirably position the inner sleeve inside the inner race ring. Additionally, each inner race member has an axially and circumferentially extending lip which extends beyond the ends of the inner sleeve for connecting the roller bearing assembly to a desirable device. Advantageously, the roller bearing device comprises only four pieces: the inner race ring, the two inner race members and the inner sleeve. Thus, the device is simple to manufacture and assemble.
