ABSTRACT:
A rolling element bearing system comprises at least one rolling element bearing with an outer race and an inner race which enclose a space containing rolling elements, which space is confined to the outside by sealing rings. At least one of the sealing rings and/or one of the races is provided with flow generating structure for feeding a lubricant into the space, as well as a filter for preventing the ingress of contaminations into the space with the lubricant. Preferably at least one of the sealing rings at its edge which slidably contacts one of the races has a shape which promotes the outflow out of the space towards the outside of the sealing ring during relative movement of the sealing ring and race.
