ABSTRACT:
A bearing assembly having dynamic drainage for lubrication oil which incls rings which are provided with races with a conical-shaped cross-section which the balls contact at pairs of side contact points. The central circumference of each ring is free; cooling oil drillings are drilled in it. This arrangement gives better oil circulation characteristics, thus improving the bearing efficiency and less heat is dissipated. Thus higher speed can be expected. The drillings responsible for drainage are inclined in the direction of rotation in order to facilitate drainage outside the roller bearing.
