How important is debugging after bearing installation?

1, after bearing installation, bearing debugging should not be ignored

After the bearing is installed, add the specified lubricant and then conduct a test run to check whether there is noise and the temperature of the bearing.

The test run should be carried out under partial load conditions, and when the speed range is large, it should be run at medium and low speeds.

Under no circumstances should spherical roller bearings be started under no load conditions and accelerated to high speeds, as the rolling components may slide on the bearing raceways, damaging the raceways, and the cage may be subject to impermissible pressure. Under normal circumstances, the bearing will make a uniform "gurgling" sound.

If the bearing emits a whistling or high-pitched sound, it indicates insufficient lubrication.

Uneven rumbling or hammering sounds from bearings are mostly caused by
