[0002] Bearings are components that fix and reduce the load friction coefficient during mechanical transmission. They are mainly used to support rotating shafts or other moving parts and guide their precise rotation or linear movement. Ball bearings are one of the most common types of bearings and are usually composed of five main parts. The inner ring and outer ring are two annular components of the ball bearing, providing a rolling track for the balls. The balls are rolling elements in the bearings, rolling between the raceways of the inner and outer rings to reduce friction and wear. The function of the cage is to evenly separate the balls so that they maintain the correct position and spacing during operation and prevent the balls from colliding with each other and getting stuck. The sealing ring is used to prevent dust, impurities and lubricant leakage, protect the cleanliness and lubrication of the inside of the bearing, and improve the service life and performance of the bearing.

These materials will cause the corrosion resistance and wear resistance of the bearing to be average, and the sealing ring is stuck in the grooves in the inner ring and the outer ring, which will cause certain friction and reduce the rotation performance of the bearing. Therefore, the technology in the field proposes a corrosion-resistant and wear-resistant bearing to solve the above problems. Utility Model Content
