<p>[Summary] The invention provides a rolling bearing assembly adapted to prevent a cage from sustaining burn-out on a guided surface thereof even when a rolling bearing is rotated at high speed, and a method of forming a lubrication device for use in the same. An annular groove 8 for storing a grease G therein is provided in adjoining relation with a guiding surface 7 of an outer ring 2, the guiding surface 7 guiding the rotation of a cage 4. An annular grease reservoir member 30, 40 storing a grease G therein is provided in proximity to the annular groove 8. The grease G stored in the grease reservoir member 30, 40 and the grease G stored in the annular groove 8 are interconnected by means of the grease G present therebetween, so as to supply a base oil contained in the grease G to a space between the guiding surface 7 and a guided surface 6. The grease is packed in an oil groove 33a, 43a of the grease reservoir member 30, 40 and the annular groove 8 of a rolling bearing A. At least one of the greases so packed is formed with a grease protrusion projecting toward the other grease. The grease G stored in the grease reservoir member 30, 40 and the grease G stored in the annular groove 8 are interconnected by means of the grease protrusion.</p> |
