Mixed ceramic ball bearings may not be as common, but their main configuration consists of inner and outer rings made of bearing steel/stainless steel + ceramic balls + PA66/stainless steel retainers + 2RS/ZZ combinations. Mixed ceramic ball bearings offer the following four major advantages during use.

(1) High-temperature resistance, with a low thermal expansion coefficient, ceramic balls do not expand due to temperature in high-temperature environments, significantly enhancing the operating temperature of the entire bearing. While ordinary bearings typically reach around 160 degrees, ceramic balls can withstand temperatures above 220 degrees.

(2) High rotation speed, with oil-free self-lubricating properties, ceramic balls have a low friction coefficient, thus making ceramic ball bearings capable of high rotation speeds. Statistically, bearings using ceramic balls can operate at speeds up to 1.5 times faster than conventional bearings.

(3) Longevity: Ceramic balls can operate without any lubrication, meaning that even when the lubricant dries out, the bearing still functions, thus preventing premature wear in conventional bearings caused by dried lubricant. Our tests and feedback from some customers indicate that the lifespan of bearings with ceramic balls is 2-3 times longer than that of conventional bearings.

(4) Insulation: The use of ceramic ball bearings allows for electrical insulation between the inner and outer rings of the bearing. Since ceramic balls are insulators, employing them between the inner and outer rings achieves insulation. This enables the bearing to be used in conductive environments.
