Dental bearings are also called dental drill bearings or dental turbine bearings,they are referred high speed miniature bearings used in dental turbine. Compared with common miniature bearings, dental bearings need to be made with refined material and with high precision,for the rotation speed of dental bearings can be from 350000~400000rpm under the air pressure of  200-250kpa,so the dental bearings need to have the following characteristics.
