Accuracy level: G5 This paragraph 3.175, 3.969, 4.762, 5.953, 6.35 is suitable for bicycle hub, center shaft, tower base repair parts modification. › See more product details; Product description Benefits of Ceramic Balls: 1. High hardness. Ordinary GCR15 bearing steel has a Vickers hardness of 800 HV, and zirconia ceramic ball hardness is 1700 HV or more. 2. High wear resistance. Ordinary steel ball milling (with an almond of one millimetre) takes about 2-4 hours, while the silicon nitride ball processing takes at least 150-200 hours (the process is different and it takes time). Corrosion resistance. The stability of ceramic materials is the best, especially silicon nitride balls, which hardly react with the substances. It is widely used in petroleum, chemical, food and other industries that need to contact strong oxidants and strong reducing agents. 4. High temperature resistance. Ceramic balls are subject to high temperatures and pressures of several thousand degrees Celsius during the sintering process. The inner molecular structure is very stable and the arrangement is very dense, which makes the thermal expansion coefficient low, and the temperature change has almost no effect on its structural size. Ceramic balls can work at temperatures up to 1200 degrees Celsius or higher. and low temperatures are little so that they are widely used in the aerospace industry. 5. Light weight. Ceramic balls weigh only 50% to 60% of ordinary steel balls and have a great promise in warehouse and aerospace fields. 6. Self-lubricating. The ceramic ball itself has good self-lubricating properties and high processing accuracy. Can reach G5, G10 degrees, ceramic ball wear-resistant and structurally stable, not easy to deform, so it can be finished and applied to many special industries. Insulation. Ceramic has good insulation.; Product description Benefits of Ceramic Balls: 1. High hardness.
