Classification of ceramic ball bearings

According to the material:The ceramic bearings can be divided into zirconia ceramic bearings, silicon nitride ceramic bearings, composite ceramic bearings.
According to the structure: ceramic bearings can be divided into: zirconia ceramic bearing with retainer, silicon nitride ceramic bearing with retainer, and composite ceramic bearing with retainer. Generally, the holding equipment of ceramic bearings is made of teflon (PTFE) as the standard configuration, and glass fiber reinforced nylon 66(grpa66-25), special engineering plastics (PEEK, PI), stainless steel (SUS316, SUS304), brass (Cu), etc. The ceramic material retainer is seldom used because of the difficulties in hole processing and forming technology. The zirconia full ball ceramic bearings, silicon nitride full ball ceramic bearings and composite full ball ceramic bearings are developed for special use.
According to the integrity of materials: the main parts of ceramic bearing mentioned above, inner and outer rings and rolling bodies are mostly made of ceramic materials, which is defined as ceramic bearing; A mixed ceramic bearing is defined when a portion of the bearing's inner and outer ring and rolling body is not made of ceramic material. Ceramic ball bearings are widely used in the mixed ceramic bearings, known as ceramic ball bearings, which can be divided into zirconia ceramic ball bearings, silicon nitride ceramic ball bearings.
