Silicon nitride bearings and bearing balls are precision ceramics sintered at high temperature in a non-oxidizing atmosphere. They feature low density, high strength, superior wear and corrosion resistance, high-temperature stability, electrical insulation, and non-magnetic properties, operating reliably under extreme conditions including high and low temperatures, vacuum, and corrosive environments. With service life and reliability far exceeding those of all-steel bearings, they are ideal for electric vehicles, high-speed spindles, wind turbines, aerospace systems, and precision machine tools.
