Excessive heat and vibration can cause premature failure of the dental bearing. This probability is prominent as the ball bearing speed is increased. To ensure smooth and silent running bearings, additional care processing the internal mating surfaces of the ball bearing components, along with the extra care required in manufacturing the components. This assembly method includes a tightened radial play to make sure that every dental ball bearing contains the identical internal properties as the next.
Shaft diameter is an important consideration for high speed dental bearings. The interior components are matched with a specially calibrated amount of radial play to ensure maximum ball bearing life. If the dental bearing is pressed onto the impeller shaft too taut, the radial play can be compromised, resulting in overheating and premature failure of the bearing. If the dental ball bearing is pressed onto the shaft incorrectly, the ball bearing will not run concentrically which can cause premature failure of the high speed dental bearing.
