A tapered roller bearing assembly, particularly for the pilot position in automotive gearboxes, in which the cage 17 is provided, adjacent the large end faces of the rollers 16 with a ring portion 27 which defines an outwardly-facing surface 21 which is urged against the tapered outer raceway 14 of the bearing to thereby form an oil seal which acts to allow oil to collect in an annular space 18. The large end faces of the rollers pass through this space and are thereby lubricated. The surface 21 may be plain or may be embossed with an oil-retaining pattern, two examples of which are described. <IMAGE>
