Hybrid Bearings
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.
