Abstract
A ball bearing having external surfaces coated with ceramic materials is provided. The raceways of the ball bearing may advantageously be formed of metal such as stainless steel. The ceramic coating acts as an insulator increasing the resistance of the ball bearing to heat within the ball bearing environment. The balls within the raceway of the ball bearing may advantageously be coated with a lubricant to decrease friction in the ball bearing because the insulating ceramic coating prevents the environmental heat from causing the degradation of the lubricant.
