Ultra High Speed Dental Bearings
Product Offering
PACAMOR KUBAR BEARINGS (PKB) ultra high speed bearings are found in many challenging applications including well known brands of high speed dental handpieces around the world. For high speed bearing applications, bearing noise, vibration, and life are all important factors which are heavily affected by both the bearing design and the intricate details of the bearing production process.
Stainless steel (440C) precision miniature & instrument ball bearings for ultra high speed applications are available in standard inch sizes and various metric sizes. A variety of special features, including, but not limited to, flanges, modified dimensions, and other unique features are offered to ensure a proper fit in the dental handpiece design.
Optional retainer materials and specialty ball materials, coatings, and shield designs are available to meet the specific requirements of your application. Please visit our fully searchable, online catalog of miniature and instrument bearings to specify a new bearing design or our Dental Handpiece Bearing Interchange for a cross reference of popular high speed dental bearings.
Ultra High Speed Bearing Design
PACAMOR KUBAR BEARINGS (PKB) manufactures ultra high speed dental bearings at our quality certified factory in Troy, NY. Pacamor Kubar Bearings (PKB) bearings for high speed dental handpiece applications offer long life at speeds approaching 500K RPM and will withstand repeated autoclaving. All high speed instrument bearings for dental and surgical applications are manufactured from 440C stainless steel, the preferred choice for all our instrument bearings. Its corrosion resistance allows for repeated sterilizing. Its highly finished, honed surface provides a long lasting structure for the 440C or Silicon Nitride (ceramic) balls, which allows the bearing to rotate smoothly at the high speeds seen in dental handpieces. Food safe oils and greases designed for high speeds and temperatures play a key role in the performance of any high speed bearing used in a dental handpiece.
For high speed applications, bearing noise, vibration, and life are all important factors which are heavily affected by both the bearing design and the intricate details of the bearing production process. To meet the unique challenges encountered by ultra high speed dental ball bearings in speeds approaching 500,000 RPM, the PKB engineering team designates a specific set of additives in our popular heat and moisture resistant Phenolic and Torlon (polyamide-imide) retainers.
High speed dental ball bearings, that run at speeds approaching 500K RPM, require special consideration. Excessive heat and vibration can cause premature bearing failure of the dental bearing. This risk is elevated as the ball bearing speed is increased. To ensure smooth and quiet running bearings, PKB performs special processing on the internal mating surfaces of the ball bearing components. In addition to the extra care involved in manufacturing the components, the assembly process includes a tightened radial play to ensure that each high speed dental ball bearing contains the same internal geometries as the next. Bores can be specially coded to ensure a consistent and reliable bearing fit on any dental handpiece shaft.
Shaft diameter is an important consideration for high speed dental bearings. The internal components are matched with a specifically calibrated amount of radial play to ensure maximum ball bearing life. If the dental ball bearing is pressed onto the impeller shaft too tightly, the radial play can be compromised and even eliminated, resulting is overheating and premature failure of the high speed dental bearing. If the dental ball bearing is pressed onto the shaft askew, the ball bearing will not run concentrically which can cause warping and failure of the high speed dental bearing.
In addition to selecting the right dental bearing retainer for your miniature and instrument bearing application, dissimilar materials can prevent component welding and extend the life of the ultra high speed bearing in a variety of applications. To this end, we offer standard 400C stainless steel or optional ceramic balls in our bearing assemblies. PACAMOR KUBAR BEARINGS ultra high speed bearings are available with up to ABEC 9 tolerances (as defined by the American Bearing Manufacturers' Association) with an optional flanged outer ring.
