Ceramic bearings, as the fundamental components for carrying mechanical rotation, are widely used in various special and harsh environments. They can be classified in many ways, mainly including the following types:
1. By the shape of the rolling element: they can be divided into two series: ceramic ball bearings and ceramic roller bearings.
2. By the application of ceramic materials:
First type: rolling elements made of ceramic materials, inner and outer rings made of bearing steel.
Second type: rolling elements and inner rings made of ceramic materials, outer rings made of bearing steel.
Third type: rolling elements and both inner and outer rings made of ceramic materials. The first and second types are called hybrid ceramic bearings, while the third type is called full ceramic bearings.
3. By material: they can be divided into zirconia ceramic bearings, silicon nitride ceramic bearings, and composite ceramic material bearings.
4. By structure: they can be divided into zirconia with retainer ceramic bearings, silicon nitride with retainer ceramic bearings, and composite with retainer ceramic bearings.
In addition, ceramic bearings can also be classified by their applications, such as high-speed bearings, corrosion-resistant bearings, anti-magnetic bearings, electrical insulation bearings, vacuum bearings, etc. Different types of ceramic bearings have different characteristics and applicable scenarios, so selection should be based on specific needs.
