    2006-8-11 · For machine speeds in the range of 500 000 rpm, the selection of a suitable bearing is a main issue. In this section, the possible choices are compiled and briefly compared. High-speed ball bearings are commonly used in the dental industry, and bearings are available for speeds exceeding 500 000 rpm. The main advantages of ball bearings are the robustness and small size.
