Tough industrial applications require special bearings. NKE hybrid bearings are consist of steel rings and bearing silicon nitride Si3N4 rolling elements. Advantages for the user of NKE HYBRID Bearings -Insulation: highest protection against passage of electric -Higher speed suitability: centrifugal force reduction due to the light rolling elements -Lightweight: Silicon nitride is 60% lighter than conventional rolling element steel -Extended service life: longer bearing life and longer re-lubrication intervals -Reduced friction: less frictional heat, especially at high speeds -High wear resistance -Higher rigidity: less deformation in rolling contact areas -Reduced risk of poor lubrication at high speeds and fast accelerations, or in the case of insufficient lubricating film -Low running noise operational bearings -Significantly less susceptible to standstill marks known as “false brinelling” -Reduced thermal expansion -More precise control of preload and bearing clearance -Dimensionally interchangeable -No additional tools required Properties of ceramic rolling elements -Electrically isolating -Low friction coefficient -Corrosion resistant -Higher modulus of elasticity
