Hybrid Bearings
Tough industrial applications require special bearings.
NKE hybrid bearings are consist of steel rings and bearing silicon nitride Si3N4 rolling elements.
Properties of ceramic rolling elements
- Electrically isolating
- Low friction coefficient
- Corrosion resistant
- Higher modulus of elasticity
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
