Judging whether bearings are damaged usually requires comprehensive consideration of the following signs:
1. Abnormal noise: Damaged bearings usually produce abnormal noise, such as rattling, whining, or metal collision. These noises may occur during bearing rotation, especially when under load.
2. Vibration and shaking: Damaged bearings can cause machine vibration and instability, and foreign objects or wear inside the bearings can cause bearing shaking. Bearing problems can be detected by observing the vibration of the equipment or using vibration monitoring equipment.
3. Temperature rise: Damaged bearings usually cause a temperature rise in the bearings and surrounding machine components, as wear generates friction and heat. The bearing temperature can be measured using an infrared thermometer or temperature sensor.
4. Changes in lubrication status: Bearing damage may cause lubricant deterioration, contamination, or reduction. Check if there are any abnormalities in the lubricant of the bearing, such as color changes, foreign objects mixing, etc.
5. Visual inspection: Check the appearance of the bearings through the eyes or with the help of a magnifying glass or shooting equipment, and observe for any abnormal wear, cracks, missing or deformed parts.
Please note that these indications are not accurate, and multiple indicators should be considered when determining whether the bearing is damaged. If there is suspicion of bearing damage, it is recommended to promptly contact maintenance personnel or bearing manufacturers for more detailed inspection and evaluation.
