It needs to have ultra-high purity, strictly controlled metallurgical qualities such as inclusion type, size, quantity and distribution, high hardness, appropriate toughness, high wear resistance and contact fatigue resistance to meet the life and reliability requirements of rolling bearings. The bearing rings are divided into inner rings and outer rings, which are connected by assembly during the bearing preparation process. During the use of the bearing, the rings and internal rollers are the main wear structures. In order to increase its service life, the rings need to be durable.
