This utility model relates to the field of bearing technology, specifically to a high-temperature resistant bearing for harsh working conditions. To address the high cost associated with existing technologies that innovate bearing materials to adapt to high-temperature conditions, two threaded holes are provided on the outer ring of the bearing. The axes of these two threaded holes are coplanar with the axis of the outer ring, and the two threaded holes are located on opposite sides of the outer ring groove. Corresponding grease tubes are threaded into each of the two threaded holes, and these grease tubes are connected to a grease injection pump and a grease extraction pump, respectively. The cage has through-holes for grease flow. As the cage rotates, the clearance between the rollers and raceways at different positions moves to the threaded holes. The two pumps simultaneously inject and extract grease from the internal grease through the two grease tubes, replacing the high-temperature grease with a low-temperature grease, reducing the internal temperature of the bearing, eliminating the need for the bearing material to withstand high temperatures, and extending the overall lifespan of the bearing.
