4. Product Specifications:

1)Dental Bearing of high precision level P4 (ABEC 7),usable for various brands of high-speed dental turbine handpieces

2)Rotating speed 350,000-450,000 rpm under air-pressure of 200-250Kpa

3)Working life for about six months under the normal operation

4)Very less vibration, Very less noise, Antirust, Corrosion resistant

5)High temperature resistant for disinfection

6)The ceramic balls used in some Freerun dental bearings are harder, lighter and more wear resistant

than the stainless steel versions used by other bearing manufacturers. Ceramic balls generate less centrifugal force at the high speeds dental handpieces operate, reducing wear on the bearing and the production of wear particles, which in turn increases lubricant life.

7. How to use correctly:1). It is the best that the interference fit between bearing bore and turbine shaft is under    0.5um-1.5um.when putting turbine shaft into bearing bore, the pressure should be forced on the face of inner ring to avoid the damage of rollway and balls.2). After fitting the bearing into turbine shaft they should be instilled special lubricant (ethanol must not be used)3). After high stean sterilized the dental high speed handpiece should be jetted somelubricant into the air inlet before used and so that bearing could be used longer time. 4). To keep operating stability, the preload spring stress of bearing should be controlled under 1.2 +/- 0.2N.
