Compared with steel bearings, ceramic bearings have several main advantages: higher hardness, no rust and corrosion, lighter weight, faster speed, and lower friction coefficient, so only some lubricating oil-bearing can be quickly rotated.
However, the toughness of ceramic bearings is lower than that of steel bearings, so it is easy to break and produce abnormal noise when encountering an impact. In addition, the replacement cost of ceramic bearings is higher. Therefore, this is the reason why more people on the market choose hybrid ceramic bearings.
