Inspection after mounting

To confirm that the bearing has been mounted correctly, perform a rotation check.

1. First, rotate the shaft or housing to see whether anything unusual can be detected.
2. Next, engage the bearing without applying a load. After observing its rotational condition at low speed, slowly increase the rotational speed and load while checking for any rise in operational noise levels, vibrations and temperature.
3. If anything unusual is detected during operation, stop the bearing and perform an inspection.

★ Checking for unusual noise or noise levels should be performed by someone familiar with the sound of properly mounted bearings operated under standard conditions.
