Hybrid ceramic bearings combine the excellent properties of metal and ceramic materials. Its main components are outer and inner rings made of bearing steel, stainless steel retainers, and silicon nitride ceramic balls. According to the data, the mechanical and physical comprehensive performance of silicon nitride ceramic balls is the best in the high-performance bearing technology field. Under normal conditions, bearing steel balls usually lose their strength and hardness at high temperatures, while silicon nitride ceramic balls can still maintain their original hardness at 400 degrees Celsius and fail at 800 degrees Celsius.

The ceramic balls in hybrid ceramic bearings have self-lubricating properties without oil, meaning they can still function properly even when the lubricating oil dries up. Their rotational speed can reach 1.5 times that of metal bearings, so they can enable engines to improve their combustion efficiency and increase their thrust.
