Ultra high speed bearings are found in numerous functions as well as high speed dental handpieces. For high speed bearing uses, noise, vibration, and reliability are all vital factors that are heavily affected by both the design and the particulars of the manufacturing process.
Stainless steel bearings for the high speed dental handpiece applications are accessible in very nearly any size. A variety of features, including, flanges, dimensions, and additional features are available to guarantee a correct fit in the dental handpiece repair.
Various retainer materials and ball materials, coatings, and shielding are available to meet the requirements of dental handpiece repair. It is essential to opt for the appropriate dental bearing retainer for the bearing used in your handpiece. Phenolic and Torlon retainers are the best option. These materials can avert component welding and lengthen the life of the high speed bearing. I believe ceramic bearings are the best answer.
These bearings allow smooth running at high speeds which will lengthen the life of your handpiece repair.
High speed dental handpiece applications require long life at speeds of five hundred thousand RPM and a few newer models are even higher. They must also withstand repetitive autoclaving. The bearings corrosion resistance is an essential concern and must allow for frequent sterilizing. Food safe oils and greases designed for high speeds and temperatures play a vital function in the performance of any high speed bearing used in a dental handpiece.
For high speed functions, bearing noise, vibration, and life are all imperative points which are greatly affected by the bearing design and the intricate particulars of the bearing fabrication procedure. To meet the unique issues encountered by ultra high speed dental bearings moisture resistant Phenolic and Torlon retainers are an evident alternative.
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 high speed 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.
Shielded bearings avoid the introduction of contamination during operation while allowing the bearing to be re-lubricated during drill maintenance.
