Maybe, in your dental life, there will spend you so much money on dental appliances and time,and you never thinking about how to solve the solution?
Ultra high speed bearings are found in numerous functions as well as dental drills. For high speed bearing uses, noise, vibrator, 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 hand piece 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 hand piece repair.
Various retainer materials and ball materials, coatings, and shielding are available to meet the requirements of dental hand piece repair. It is essential to opt for the appropriate dental bearing retainer for the bearing used in your hand piece. Phenolic retainers are the best option. These materials can avert component welding and lengthen the life of the bearing. These bearings allow smooth running at high speeds which will lengthen the life of your hand piece repair.
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 bearing used in a dental hand piece. 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.
At a couple dollars for a bur and dental turbines which can cost as much as $300, the trade off is certainly worth considering. Consider also, that a new carbide bur or two for every patient will add speed and efficiency, fewer post op patient symptoms, and is much easier on the doctor's hand, requiring much less pressure for the desired result.
At 350,000 - 500,000 revolutions per minute, the dental handpiece turbine is in somewhat of a delicate state when in operation. There are two, very damaging, affects the dental bur can have on the turbine while in this condition:
Turbine bearing failure due to bur eccentricity causing high vibration, which is highly compounded at the operating speeds of a dental handpiece. Slight bends in used dental burs which would be undetectable by the human eye will cause high vibration.
Dental burs require more axial pressure exertion via the doctors hand, which can cause rotating turbine (usually impeller) to come into contact with stationary handpiece head.
