Ceramic Bearings: Bones of Tomorrow
Ceramic bearings are a new type of bearing that is made from ceramic materials, such as silicon nitride or zirconia. They are much harder and more durable than traditional steel bearings, and they can withstand higher temperatures and speeds. This makes them ideal for use in a variety of applications, including medical implants, aerospace components, and high-performance machinery.
