Lubrication inspection of motor bearings is an important step to ensure the normal operation of the motor and extend the life of the bearings. The following are the steps to check the lubrication of motor bearings:

Regular lubrication: Ensure that the motor bearings are lubricated regularly. According to the recommendations of the motor manufacturer, develop a suitable lubrication plan to ensure that the bearings are running under proper lubrication conditions.

Lubricant selection: Use appropriate lubricants. According to factors such as bearing model, working environment and temperature, choose the appropriate lubricant, which can be grease or oil.

Lubricant cleanliness: Ensure the cleanliness of the lubricant. Before injecting the lubricant, make sure the lubricant is clean to prevent impurities and particles from entering the bearing.

Lubrication quantity control: Control the amount of lubricant. Too much or too little lubricant may have a negative impact on the bearing. Make sure the amount of lubricant injected is within the range specified by the manufacturer.

Lubrication system status: Check the status of the lubrication system. Ensure lubrication systems, such as grease injection devices or oil circulation systems, are in good working order and have no blockages or leaks.

Temperature monitoring: Monitor the temperature of the bearing using tools such as infrared thermometers. Overheating of the bearing may be a sign of insufficient lubrication or other problems.

Grease appearance: Check the appearance of the grease. If the grease exhibits an unusual color, odor, or texture, it may need to be replaced.

Grease aging: Check the aging of the grease. Aged grease may lose its lubricating properties and need to be replaced regularly.

Bearing noise: Listen for noise from the bearing. Unusual noises may be an indication of bearing problems and require further inspection.

Vibration monitoring: Use vibration monitoring equipment to detect the vibration level of the bearing. Unusual vibrations may indicate bearing problems.

Record maintenance: Record details of lubrication maintenance, including lubrication time, lubricant type and amount, grease changes, etc. This helps to develop a more effective maintenance plan.
