Advantages of hybrid ceramic bearings
advantage
(1) High temperature resistance. The thermal expansion coefficient of ceramic ball is small, and the bearing ball will not expand due to temperature under high temperature environment, which greatly improves the service temperature of the whole bearing. The temperature of ordinary bearing is about 160 ℃, and the temperature of ceramic ball can reach more than 220 ℃.
(2) High speed. The ceramic ball has the oil-free self-lubricating property and the friction coefficient of the ceramic ball is small, so the ceramic ball bearing has a high speed. According to statistics, the rotating speed of bearings with ceramic balls is more than 1.5 times that of ordinary bearings.
(3) Long service life. The ceramic ball can be free of any grease, that is to say, even if the grease is dry, the bearing can still work. In this way, the premature failure of bearings caused by grease drying in ordinary bearings can be avoided. According to our test and feedback from some customers, the service life of the bearing after using ceramic ball is 2-3 times that of the ordinary bearing.
(4) Insulation. The bearing with ceramic ball can insulate the inner and outer rings of the bearing. Because ceramic ball is an insulator, the insulating effect can be achieved by using ceramic ball between the inner and outer rings of the bearing, so that the bearing can be used in a conductive environment.
