Abstract
A cage for a ball bearing is formed by a series of side rings connected in a circular arrangement by crosspieces. The crosspieces have surfaces formed thereon for defining cage pockets in which balls are inserted and held. Each side ring is thin-walled, whereas the crosspieces are relatively thick, so that the cage is elastic. The walls of each cage pocket comprise four circular cylindrical surfaces, an opposing pair of which are integrally connected to converging conical surfaces formed on the projections. The projections may extend either radially inwardly or radially outwardly from the crosspieces or both. The balls of the bearing are held in the pockets by the converging conical surfaces.
