CoorsTek ultra-precise Cerbec® Bearing Balls are ideal for use in wind turbines, available in up to 50 mm diameters. The inherent dielectric properties of silicon nitride (Si3N4) provide electrical insulation in generator bearings — eliminating stray current damage and premature failure. Their unique design, composition, and finish allow each wind turbine to be more energy and cost efficient. These benefits include:
Electrical insulation - eliminate stray current damage & premature failure
Reduced friction- less lubrication, wear, and increased efficiency
Lighter weight- reduced starting and operating torque
Tight tolerance- increased life and decreased maintenance
