Flange Block BearingsName: Ceramic BallMaterial: Silicon NitrideQuantity: 2 piecesAdvantages of Silicon Nitride Balls1. High hardness. The hardness of ordinary bearing steel is 800HV, while the Vickers hardness of silicon nitride balls can reach 1600 (HV10).2. High wear resistance. Taking our company's product processing process as an example, the grinding time of ordinary steel balls (one millimeter margin) is about 2-4 hours, while the processing of silicon nitride balls requires at least 150-200 hours.3. Corrosion resistance. Ceramic materials, especially silicon nitride balls, are stable and rarely react chemically with any substance. They are widely used in industries such as petroleum, chemical, and food that require contact with strong oxidants and strong reducing agents.4. High temperature resistance. Ceramic balls experience several thousand degrees of high temperature and huge pressure during the sintering process. Their internal molecular structure is very stable and the arrangement is very dense, which makes their thermal expansion coefficient very low, and temperature changes have almost no effect on their structural dimensions. The working temperature of ceramic balls can reach 1200 degrees or even higher, and low temperature has little effect on them, so they are widely used in the aerospace field.5. Light weight. The weight of ceramic balls is only 50%-60% of ordinary steel balls, and has great prospects in the fields of bearings, aerospace, etc.6. Self-lubrication. Ceramic balls have good self-lubrication properties and high processing precision, which can reach G5 and G10 levels. Ceramic balls are wear-resistant and have stable structures and are not easy to deform, so they can be finely processed and applied in many special industries.7. Insulation: Ceramics have good insulation effect.Material: Bearing steelModel: MR115 ZZ 5*11*4mm
