This invention relates to the field of radial thrust bearing technology, specifically a radial thrust bearing comprising an inner ring, an outer ring, a cage, and balls, and a circulation mechanism. The inner ring is fitted inside the outer ring, and the balls are rolled and embedded between the inner and outer rings. The cage is installed between the inner and outer rings, with the balls located on the cage. The circulation mechanism is installed on both sides of the outer ring. This invention solves the problem that existing bearings still generate high internal temperatures at high speeds. High temperatures reduce the viscosity of the lubricating oil, leading to a thinner oil film, increased friction, and ultimately, accelerated bearing temperature rise. Excessive bearing operating temperature can cause the bearing to seize due to thermal stress. This invention achieves uniform heat transfer from the lubricating oil at high speeds, preventing the bearing from seizing due to excessive operating temperature.
