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 some
lubricant 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.
