Abstract
A tandem roller bearing assembly is provided that combines a tapered roller bearing with an angular contact ball bearing, yielding high load capacity with improved efficiency. A one-piece outer ring contains an outer tapered roller raceway and an outer angular contact ball raceway and can support an axial load in a single direction. A one-piece inner ring contains an inner tapered roller raceway and an inner angular contact ball raceway and can support an axial load in a single direction. Various rib configurations are implemented on the inner tapered roller raceway to achieve multiple friction and axial load support options.
