Abstract

The bearing assembly incorporates rollers (7) located by a cage (9) in relationship to e.g. a rotatable shaft (11) and a sleeve (1). The cage is contoured ribbed or grooved to promote circulation of lubricant through the bearing. The ribs etc. are provided on cage edges or on the intervals between roller windows. The ribs may be integral with the cage, or may be separate pieces welded to the cage. The rollers may be located circumferentially by a thin-walled sleeve cage (9) with roller windows and cut and folded flap oil impellers (17).
