Is the temperature of the deep groove ball bearing stable during initial operation?

The temperature of deep groove ball bearings is not stable during initial operation. As a widely used core component in mechanical transmission systems, the temperature characteristics of deep groove ball bearings are influenced by various factors. In the initial operation stage, due to factors such as the fit between the bearing, shaft, and bearing seat, the distribution and state of lubricants, and the release of internal stress in the bearing, the temperature may experience a fluctuating and gradually stabilizing process.
Specifically, bearings may have certain interference fit or clearance during assembly, which can result in additional friction and heat during initial operation. At the same time, lubricants may not be evenly distributed in the initial stage, which can also affect the lubrication effect and temperature distribution of bearings. In addition, the stress inside the bearing will gradually release during initial operation, which will also affect the temperature.
Therefore, deep groove ball bearings may experience a process of temperature rise and gradual stabilization during initial operation. In order to ensure the normal operation and prolong the service life of bearings, it is necessary to closely monitor the temperature changes of bearings and take necessary measures to control the temperature. For example, suitable lubricants can be selected, the fit clearance of bearings can be optimized, and the cooling and heat dissipation of bearings can be strengthened.
