With a higher performance than traditional steel bearings, hybrid bearings are a combination of steel or stainless steel rings, used in conjunction with silicon nitride ceramic balls.
As new technologies emerge, rolling elements (ceramic balls) of the highest quality, which on some occasions can take up to 60 days to manufacture, can be up to 58 percent lighter, four times smoother, and have a 70 percent reduced thermal expansivity. This can typically run at operating temperatures between 14 to 47 percent lower than standard steel bearings.
A combination of these pioneering properties can heighten efficiency, ensure that the bearings are less prone to the effects of contamination and corrosion, and allow a greater intolerance to heat.
