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 hand piece 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.
