How to ensure the normal operation of small and medium-sized deep groove ball bearings in high temperature environment?

First, make sure that the selected small and medium-sized deep groove ball bearings are made of high temperature resistant materials. For example, alloy steels such as Cr14Mo4 can still maintain high thermal strength and impact toughness at high temperatures, and are suitable for high temperature environments below 550°C. The selection of this material is crucial to improving the bearing's load-bearing capacity and stability at high temperatures.
In high temperature environments, the selection of lubricants is crucial for the normal operation of bearings. It is recommended to use graphite-based high-temperature lubricants for lifelong lubrication of bearings, which can still maintain stable lubrication performance at high temperatures. For bearings that require relubrication (such as open VA201 bearings), lubricants should be checked and added regularly to ensure that the bearings are in good lubrication condition.
Controlling bearing temperature through effective cooling measures is the key to ensuring the normal operation of bearings in high temperature environments. Cooling methods such as air cooling and water cooling can be used to control the bearing temperature within a reasonable range. At the same time, pay attention to avoid rapid temperature changes of the bearing to reduce the generation of thermal stress and thermal deformation.
In high temperature environments, bearing maintenance is particularly important. The lubrication status, sealing performance and wear of the bearings should be checked regularly, and severely worn bearing parts should be replaced in time. In addition, keeping the environment around the bearing clean and dry and preventing dust and moisture from entering the bearing are also important measures to ensure the normal operation of the bearing.
