Lubricating oil insertion system

PURPOSE: To accurately supply lubricating oil to a contact part of a bearing without causing loss by providing a means for supplying lubricating oil to a predetermined position of the bearing and a cage means for catching lubricating oil supplied to the predetermined position. CONSTITUTION: When a predetermined amount of lubricating oil is discharged from a supply pipe 4, oil droplets 11 are formed on a face of the supply pipe 4, and the grown oil droplets 11 come into contact with an inner race 5, are pushed away to a position of a cage 7, and collide against an elongation part D 1 of the cage 7. Then, since surfaces of an inside diameter and an outside diameter of the cage 7 have angles, the oil receiving a centrifugal force is led to the maximum outside diameter point B, and the point B coincides with a running track 10. The oil not caught by a ball 8 is thrown away to the outside so that it comes into contact with an outer race 6 in a normal part of the running track 10. Since an outer corner 12 of the cage 7 is round, the oil in contact with an outer face of the cage 7 creeps up to the point B along the cage 7 and is not thrown away to the outside of a bearing.
