50 1/4" Inch G5 Precision Si3N4 Silicon Nitride Ceramic Bearing Balls

These superior precision ceramic Si3N4 bearing balls are great for applications were there will be extreme rotation and a premium performance bearing ball is required to meet the demands. Lighter and stronger than tungsten carbide, these silicon nitride balls are diamond polished and guaranteed not to shatter or melt in the most extreme conditions.

• The finest quality silicon nitride produced in accordance with the highest industry standards
• High precision G5 ball bearings
• Modern furnaces with precisely controlled atmospheres and temperatures are used for heat treating to assure uniform hardness and proper microstructure for each silicon nitride ball
• Throughout the manufacturing process, statistical process control assures tolerance accuracy, fine surface finish and consistent high quality
