Dental Bearing

Dental bearings, also known as dental drill bearings or dental turbine bearings, are high-speed micro bearings used for dental turbines. The inner and outer rings of dental bearings are made of refined 440 stainless steel, the balls are made of high-precision stainless steel (440) or ceramic (Si3N4) according to requirements, and the cage is made of reinforced phenolic resin (TORLON) or phenolic resin (PEEK). The accuracy tolerance of dental bearings is ABEC-7 (P4). At a pressure of 200-250kpa, the rotational speed of dental bearings can reach 350000-45000rpm, so the requirements for using dental bearings are very high. The dental bearings (dental drill bearings) of SXD have the characteristics of high precision, high speed, low noise, low vibration, high temperature resistance, corrosion resistance, long service life, and environmental protection.
