The invention discloses a hydrostatic pressure lubrication bearing and belongs to the technical field of numerical control machine tool parts. The hydrostatic pressure lubrication bearing comprises an oil tank used for containing pressure oil, an oil pump and a sliding bearing; one end of the oil pump is connected with the oil tank, and the other end of the oil pump is connected with the sliding bearing; the sliding bearing is provided with a bearing bush, a plurality of oil cavities and a bearing hole used for containing a journal; the journal is arranged in the bearing hole; the two ends of each of the oil cavities communicate with the oil pump and the bearing hole; and in use, through the oil pump, the oil tank injects the pressure oil into the bearing hole by means of the oil cavities so that the journal can be suspended in the bearing hole and form a lubrication oil film together with the bearing bush. The lubricating oil film of the hydrostatic pressure lubrication bearing is formed by the outside pressure oil and can achieve liquid friction between the journal and the bearing bush under the conditions of starting, shutdown, high speed, low speed or reversing, the bearing bush is not abraded, the service life of the bearing is prolonged, and the application range is wide.
