Abstract

A bearing assembly comprising a rotating outer race (1) supported on sets of rollers (3) relative to inner race (2) with one or more lubricant charge devices (7) adapted to facilitate the controlled purging of used grease from the bearing chambers (3A). Each lubricant charge device (7) is secured to a rotating component of the bearing assembly, in operative relationship to an adjacent stationary surface (2A), and includes an entrapment surface (14A) defining a grease entrapment region (14). As the lubricant charge device (7) is rotationally carried past one or more grease purge port orifices (9), used grease accumulated within the grease entrapment region (14) is forced into the orifice (9) by the entrapment surface (14A) for subsequent extraction through the purge port (8).
