摘要

A rolling element bearing system comprises at least one rolling element bearing (1;34;65 and 66) with an outer race (2;21;51;57) and an inner race (5;20;50;58;69) which enclose a space containing rolling elements (7;23;52;59 and 60), which space is confined to the outside by means of sealing rings (9;24 and 25;28 and 29;35;54 and 55). At least one of the sealing rings and/or one of the races (57) is provided with flow generating means (12;27;31;54-56;61) for feeding a lubricant into said space, as well as filtering means (19;26;30;36;53;64;71) for preventing the ingress of contaminations into said space with said 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 said space towards the outside of said sealing ring during relative movement of said sealing ring and race.
