Power loss of rolling bearing
What is the reason for the power loss of rolling bearings? Reasons for power loss of rolling bearings;

1. Resistance loss: There is contact resistance and rolling friction between the balls, raceways, cages and other parts in the rolling bearing, which makes it necessary to overcome these resistances when the bearing rotates, resulting in certain power loss.

2. Sealing performance: Some rolling bearings need to be sealed to prevent dust, moisture and other impurities from entering, but there is also some contact resistance and friction between the seal and the inner and outer rings.

3. Lubrication conditions: The rolling bearing needs to add grease to reduce friction and wear, but the grease will produce resistance and consume a certain amount of energy to produce lubrication effect.
