Thin - walled bearings are widely used in fields such as precision instruments and automated equipment due to their advantages of compact structure, light weight, and small space occupation. However, in the actual operation process, thin - walled bearings may experience abnormal heating. This not only affects the operation accuracy and stability of the equipment but also may cause damage to the bearings themselves, increasing maintenance costs. Therefore, figuring out the causes of abnormal heating and adopting corresponding solutions is of great significance for ensuring the normal operation of the equipment. This article will introduce the causes and solutions of abnormal heating of thin - walled bearings in detail for you.

1. Causes of Abnormal Heating of Thin - walled Bearings

Excessive load: When the load borne by the equipment during operation exceeds the rated load of the thin - walled bearing, the contact stress between the rolling elements and the raceway inside the bearing will increase sharply, and friction will intensify, thus generating a large amount of heat and causing the bearing to heat up.

Poor heat dissipation conditions: Thin - walled bearings are installed in a closed or poorly ventilated environment, and the heat generated during operation cannot be dissipated in time. As heat accumulates continuously, the temperature of the bearing will rise abnormally.
