        Dental drill bearings are special bearings for dental dentists. The inner ring of the dental drill bearing is made of refined stainless steel (9Gr18) material; the ball is made of refined stainless steel (9Gr18) or non-metallic super-hard ceramic (Si3N4) material, which has good wear resistance; the cage has high strength and low wear resistance, and There are self-lubricating properties of polyimide or 80-120 phenolic cloth bakelite materials.


        The dental drill bearing can reach a speed of 350,000-400,000 rPm under the air pressure of 200-250Kpa. Under normal conditions of use, dental drill bearings have a working life of more than 6 months.
