Hybrid ceramic deep groove ball bearings are made of stainless steel or high-quality bearing steel inner and outer rings, ceramic balls, (polyamide 66 or nylon 66) cage, rubber seals or metal seals. The design of this type of bearing is the same as ordinary deep groove ball bearings. , The difference is that different materials are used to meet the needs of special purposes.
Hybrid ceramic deep groove ball bearings, especially silicon nitride ball hybrid ceramic bearings, have the characteristics of low density, high hardness, low friction coefficient, anti-magnetic and electrical insulation, wear resistance, self-lubricating and good rigidity, good acid and alkali resistance, self-lubricating function, High temperature resistance above 300°C, high wear resistance, high speed greatly reduces rolling, friction and heat generation, long service life is 3 to 5 times that of all-steel bearings, light weight ceramic materials 60% lighter than chrome steel bearings, and the same rigidity The elastic mold of ceramic material is 50% higher than that of bearing steel.
Advantages of Hybrid Ceramic Ball Bearings
1. High temperature resistance,
The thermal expansion coefficient of ceramic balls is small, and the bearing ball will not expand due to temperature in a high temperature environment, which greatly increases the operating temperature of the entire bearing.The temperature of ordinary bearings is about 160 degrees, and the temperature of ceramic balls can reach more than 220 degrees.
2.High speed
Ceramic balls have oil-free and 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 1.5 times the speed of general bearings.
3. Long service life
The ceramic ball can be moving without any grease, that is to say, even if the grease dries out, the bearing can still operate, which avoids the occurrence of premature bearing damage caused by the drying out of the grease in ordinary bearings. The service life of ceramic deep groove ball bearings is 2-3 times that of ordinary bearings.
4.Insulation function
This is also the most characteristic point. Bearings using ceramic balls can insulate the inner and outer rings of the bearing. Because ceramic balls are insulators, ceramic balls can be used between the inner and outer rings of the bearing to achieve the insulation effect. In this way The bearing can be used in a conductive environment.
Hybrid ceramic deep groove ball bearings are particularly suitable for high-speed, high-precision and long-life steel-ceramic hybrid bearings rolling elements (the inner and outer rings are made of metal). 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.
