Abstract
A unitized cage for cylindrical roller bearings wherein the inner raceway of the bearing configuration may be the rotating or stationary shaft component and the outer raceway of the bearing configuration may be the rotating or stationary housing component. Thus, a bearing configuration can be generated without the need for a separate inner or outer race having inner or outer raceways. The unitized cage comprises a cage nest having end face axial projections and a cage finger ring having fingers which engage the end face axial projections to lock the cage nest into position on the cage finger ring. A plurality of cylindrical rollers can be positioned within the cage pockets of the cage nest prior to the assembly of the cage nest with the cage finger ring to generate a cylindrical roller bearing.
