Most bearings are currently made primarily from steel, but they fail relatively quickly under high loads, temperatures, as well as abrasive, corrosive, chemical and other types of wear. Replacing steel balls with ceramic balls, i.e. creating hybrid bearings, in many cases allows achieving significantly higher performance and expanding the range of functionality of the devices in which they are used. For example, hybrid ball bearings take advantage of ceramic rolling elements with high quality surface treatment of steel rings, which allows for longer service life and better performance at high
