Dental Drill Bearings are called dental bearings,dental turbine bearings or dental handpiece bearings in difference places, they are referred high speed miniature bearings used in dental turbine. Compared with common miniature bearings, dental bearings need to be made with refined material and with high precision,for the rotation speed of dental bearings can be from 350000~400000rpm under the air pressure of 200-250kpa,so the dental bearings need to have the following characteristics of high precision, high speed, low noise, low vibration, high temperature resistance, corrosion resistance, long life and environmental protection, which are deeply loved and recognized by users.
Runstar is a professional dental drill bearings manufacturer, we have been committed to the R & D and production of high-precision dental drill bearings(dental bearings) since 2007.
There are some different shapes of dental drill bearings in Runstar, we have full sizes of dental bearings, the item SR144TLZWN is belong to smooth type of dental drill bearings in shape, no flange or step on outer ring, it is a very pop size in market.It is made of refined stainless steel with high precision ABEC-9, and it is with a bore diameter 3.175mm,a outer diameter 6.35mm and a width 2.78mm. And it is with a shield in one side that is easy for user to reduce the temperature of the dental drill handle with water.In order to improve the speed,we use ceramic balls for the dental drill bearings.
