The utility model discloses a composite solid lubrication bearing of a bogie of a hot metal car. The composite solid lubrication bearing comprises a bearing outer ring, a bearing inner ring, and balls which are arranged between the bearing outer ring and the bearing inner ring; a bearing body of the hot metal car is fixed on a bearing pedestal through the bearing outer ring; the bearing pedestal is fixed on a bogie cross beam; a plurality of holes which are used for embedding a composite solid lubricant are formed in the bearing outer ring. According to the composite solid lubrication bearing, the a composite solid lubricant is put between the inner ring and the outer ring for lubrication through the movement of the balls. Through the special treatment, the service life of the bearing is prolonged by three times, a lubrication material is saved by more than 6 times, the mechanical maintenance frequency is decreased by three times, the oil leakage of a bearing box can be automatically treated, and the running temperature is reduced by 5-17 DEG. According to the composite solid lubrication bearing, the regular lubrication maintenance link of the bogie bearing can be saved, so that the use cost and the maintenance cost are reduced.
