In dental air turbines, miniature rolling bearings must overcome a very demanding set of challenges. As well as rotating at speeds of up to 500,000 rpm, these bearings must provide extremely quiet operation and meet rigorous hygiene requirements. NSK offers precision miniature bearings made from stainless steel especially for this application.
Driven pneumatically by a turbine wheel, the two bearings in the head of the instrument ensure stable guidance of the drill during dental procedures. Miniature bearings, which have an outer diameter of just 6.35 to 7 mm, need to attain speeds of up to 500,000 rpm and stop very
