Bearing maintenance


1. The bearing shall be stored in a clean and dry environment, and the temperature and humidity shall be controlled in handling and storage. The temperature and humidity shall be within an acceptable fixed range and shall be more than 30cm from the ground.

2. Some bearings have a certain shelf life. For example, bearings with dust caps and oil seals, when stored for a period of time, the starting torque of the bearing will be larger than that of the new bearing, and the lubrication performance of the grease will be damaged due to the long time of storage.

3. In order to ensure the normal and reliable operation of the bearing, sufficient lubrication must be applied to prevent direct metal contact between the rolling body raceway and cage, causing wear and bearing surface corrosion. Therefore, in various applications, it is very important to choose the appropriate lubricant and lubrication method, at the same time, it also needs correct maintenance.

4. Lubricant mainly based on the operation condition of actual choice, namely: the temperature range and speed as well as the surrounding environmental impact if can ensure reliable lubrication, the bearing lubricant used dose the most hours, the lowest operating temperature, but at the same time other role, such as sealing, consumption will increase accordingly when installing a bearing, filling grease is generally not the remaining space filled with the bearing, bearing box control the remaining space of 1/3, 1/2, much more susceptible to high temperature.
