Do you know the advantages of ceramic bearing hybrid?

Ceramic bearing hybrid, especially the silicon nitride ball hybrid ceramic bearing has the characteristics of low density, high hardness, low friction coefficient, anti-magnetic and electrical insulation, wear resistance, self-lubricating and good rigidity.
Ceramic bearing hybrid has good acid and alkali resistance, self-lubricating function, high temperature resistance above 300°C, high wear resistance, high speed, greatly reducing rolling, friction and heat generation, and long service life is 3~5 of all steel bearings Times, lighter weight Ceramic material is 60% lighter than steel, and the elastic mold of the same rigid ceramic material is 50% higher than that of bearing steel.

Ceramic bearing hybrid is particularly suitable for rolling elements of high-speed, high-precision and long-life steel-ceramic hybrid bearings (metal inner and outer rings). Generally, the inner and outer rings are made of bearing steel or stainless steel, and the ceramic balls can be made of ZrO2, Si3N4, or SiC.
Among them, Si3N4 has excellent comprehensive performance and has become the preferred material for steel-ceramic hybrid bearings.
Advantage
(1) The ceramic bearing hybrid has high temperature resistance, and the ceramic ball has a small thermal expansion coefficient. It will not cause the bearing ball to expand due to temperature in a high temperature environment, which greatly increases the use temperature of the entire bearing. The temperature of the ordinary bearing is about 160 degrees. The ceramic ball can reach 220 degrees or more.

(2) The ceramic bearing hybrid has a high speed, ceramic balls have oil-free self-lubricating properties, and the friction coefficient of ceramic balls is small, so ceramic ball bearings have a high speed. Bearings using ceramic balls are more than 1.5 times the speed of general bearings. Rotating speed.
(3) The ceramic bearing hybrid has a long life, and the ceramic ball can be added without any grease, that is to say, even if the grease dries out, the bearing can still operate, so as to avoid the occurrence of premature bearing damage caused by the drying of grease in ordinary bearings. According to our tests and feedback from some customers, the service life of the bearing after using ceramic balls is 2-3 times that of ordinary bearings.
(4) The last and most important point is ceramic bearing hybrid insulation. Bearings with ceramic balls can insulate the inner and outer rings of the bearing, because ceramic balls are insulators, and ceramic balls are used between the inner and outer rings of the bearing. Can achieve the effect of insulation. In this way, the bearing can be used in a conductive environment.
