Single Row Angular Contact Bearings
A single-row angular-contact ball bearing wherein an annulus of balls engages the concave external race surface of the inner race and the concave internal race surface of the outer race. The outer race has a circumferentially complete ball confining portion which is outwardly adjacent to but spaced from the race surface of the inner race and is normally out of contact with the balls. The inner race has a circumferential complete ball confining portion which is inwardly adjacent to but spaced from the race surface of the outer race and is normally out of contact with the balls. The material of those portions of the races which define the respective race surfaces is a hardened metal, and the material of the confining portions is unhardened metal. The confining portions may be integral with or are produced separately and thereupon assembled with the respective races.
