Abstract

A spherical roller bearing having a specific pitch circle diameter (PCD) that includes an outer ring, an inner ring, a plurality of roller elements arranged in first and second roller rows, each roller element providing an axially inner end, and a cage for guiding the roller elements in the first and second roller row, the cage having a plurality of cage pockets. One of the roller elements disposed within each cage pocket. Each respective cage pocket has a bottom that faces the axially inner end of the roller element in each cage pocket. A radially inner end of the cage pocket bottom contacts the axially inner end of the roller element only at a location radially equal to the specific PCD, the cage pocket bottom angled such that the cage pocket bottom abuts the axially inner end of the roller element at an angle such the contact is not flush.
