Material and performance characteristics of dental drill bearing:
The material of the dental drill bearing is very important to its performance and life. The ring material is made of special corrosion-resistant stainless steel, the ball material is made of Si3N4 ceramic ball with small thermal expansion coefficient, and the cage material is made of polyimide TORLON which is resistant to pressure, impact and high temperature. The selection of these materials enables the drill bearing to operate in an environment with poor lubrication conditions and has the characteristics of corrosion resistance and no rust.

Dental drill bearing working principle and application scenarios:
The dental drill bearing is fitted with turbine, bearing and shaft by interference, and is driven by compressed air to rotate at high speed, driving the spring chuck installed in the shaft hole and the drill to work. This design enables the drill bearing to have ultra-low vibration and ultra-low noise at high speeds, making it suitable for a variety of dental applications.
