Hybrid ceramic deep groove ball bearings – Silicon Nitride (SI3N4)

Hybrid ceramic bearings are a specialized type of bearing that combines ceramic rolling elements (usually silicon nitride balls) with metal inner and outer raceways (typically made of steel). This hybrid construction aims to take advantage of the unique properties of both ceramic and metal materials.

• Reduced Friction: The ceramic balls have a smoother surface and lower friction coefficient, leading to reduced heat generation and increased efficiency.
• Longer Life Span: The hard ceramic balls are less susceptible to wear and deformation, often resulting in a longer service life compared to all-metal bearings.
• Electrically Insulating: The ceramic rolling elements provide electrical insulation, making these bearings useful in applications where electrical currents could otherwise damage metal bearings.
• High-Speed Capability: Lower friction and reduced heat generation make hybrid ceramic bearings suitable for high-speed applications.
• Lower Weight: Ceramic materials are lighter than steel, resulting in a lighter bearing and reduced rotational inertia.
• Corrosion Resistance: While not as corrosion-resistant as full ceramic bearings, the ceramic elements in hybrid bearings do offer some level of resistance against corrosive environments.
• Cost-Effective: Generally more affordable than full ceramic bearings but offer many of the same advantages.
