How can mechanical rotating bearings generate heat

How can mechanical rotating bearings generate heat

Based on past experience, bearing heating is generally caused by the following reasons:

1. Excessive load, including uneven load, etc;

2. Assembly is too tight (shaft and bearing, bearing and bearing seat);

3. Poor lubrication, particularly prominent at high speeds;

4. The working conditions are harsh, such as the bearings of the oven fan. If the design is poor, the working environment temperature will be around 6.70 degrees Celsius. If it works even a little, it will burn out on Baidu Le.
