What is the difference between full ceramic bearings and hybrid ceramic bearing?

When it comes to ceramic bearing, we must think of ceramic bearing the whole bearing made of ceramic materials are used, in fact, there are two types of ceramic bearing is points, including full ceramic bearings and hybrid ceramic bearing. Full ceramic bearing as the name implies, is known as the ring of the bearing and the ball is the use of ceramic materials. The hybrid ceramic bearing is ring is made of bearing steel with ceramic material of the ball. Ceramic bearing features: 1, the accuracy level: ABEC - 1，ABEC- 3，ABEC- 5，ABEC- 7，ABEC- 9. Usually start abec5 grades, including abec7 and abec9 called high precision bearings. In addition, some customers also care about the level of ceramic ball, usually adopt ceramic ball hierarchy as the G3, the G5, G10, G16, the smaller the value, the higher the precision. 2, the bearing size: we can offer the smaller inner diameter of 2 mm miniature ceramic bearing, can also provide large ceramic bearing inner diameter 400 mm. We can provide the inch and metric sizes of the ceramic bearing. 3, sealing form: under normal circumstances, the full ceramic bearing is open not sealed, but we can provide the full ceramic bearing with PTFE sealing. The advantages of ceramic bearing: ( 1) And high speed. Especially for hybrid ceramic bearing, high speed can reach 450000 RPM, is mainly used in dentistry, mobile phones and main shaft areas. （ 2) And heat resistance. In high temperature is 1200 degrees Celsius. （ 3) And corrosion resistance. The material itself has the corrosion resistant special it can be applied to acid, alkali, inorganic, organic salt, water, etc. , areas of application: electroplating equipment, electronic equipment, chemical machinery, shipbuilding, medical apparatus and instruments. 。 。 。 。 。 （ 4) , nonmagnetic: ceramic bearing no magnetic, not can absorb dust to reduce bearing wear and noise. Application examples, such as degaussing equipment, precision instruments field. （ 5) , insulation: due to the high resistance to avoid arc damage of bearing, the bearing can be used for necessary use in electronic equipment. （ 6) , high vacuum, because the ceramic material has the lubrication oil free, ceramic bearing can be used in ultra high vacuum environment.
