What is the minimum operating temperature for silicon nitride bearings?
Silicon nitride ceramic balls are precision ceramics sintered at high temperature in a non-oxidizing atmosphere. They have high strength, high wear resistance, high temperature resistance, corrosion resistance, acid and alkali resistance, can be used in seawater for a long time,
How fast can ceramic bearings withstand?
First of all, it depends on whether it is an all-ceramic bearing or a ceramic ball bearing (hybrid bearing). If it is an all-ceramic bearing, the speed is usually lower than that of a steel bearing. If it is a ceramic ball bearing, it can theoretically achieve a higher speed than a steel bearing. However, the specific speed needs to be analyzed according to the specific model/accuracy/configuration.
High-performance ceramic ball hybrid bearings will be more widely used in wind turbines
Many companies that started to develop wind turbines have recently begun to realize the advantages of high-performance ceramic ball hybrid bearings, especially the use of ceramic ball hybrid bearings can increase the speed of the rotor shaft of the wind turbine blade from 30rpm to 2000rpm to generate more electrical energy.
According to the news on the website of the Ministry of Science and Technology on the 19th, the Beijing Sinoma Artificial Crystal Research Institute Co., Ltd. has successfully completed the acceptance of the major scientific and technological achievements transformation project in Beijing "Research and Industrial Development of Silicon Nitride Ceramic Bearing Balls for Wind Power Bearings".
Nano-ceramics, in essence, refer to ceramics that have nano-effects due to their small grain size to the nanometer level. There are currently no three-dimensional nano-ceramics on the market. Therefore, the ceramic balls and ceramic bearings we see with the naked eye do not have the so-called nanometer.
Are ceramic bearings corrosion resistant?
The reaction speed of ceramic itself with acid and alkali is very, very slow, so from the perspective of acid and alkali corrosion resistance, the life of ceramic bearings is many times longer than that of stainless steel bearings.
Ceramic materials are an important family of inorganic non-metallic materials in addition to metals and polymers. Industrial ceramic materials are usually composed of crystal phase, glass phase and gas phase, of which crystal phase is the most important component, and its structure, morphology, quantity and distribution determine the properties of ceramic materials.
