What are the causes of bearing damage?

What are the causes of bearing damage?

1. Material fatigue: Long-term operation or excessive use may cause bearing material fatigue, especially under high load, high-speed operation or frequent start/stop conditions.

2. Poor lubrication: Insufficient lubrication, grease contamination, improper lubrication method or wrong lubricant selection may lead to poor bearing lubrication, increase friction and wear, and thus shorten bearing life.

3. Pollution: Dust, impurities, moisture or other contaminants in the environment may enter the bearing, causing bearing wear, corrosion or blockage, affecting bearing performance.

4. Installation problems: Incorrect installation methods, failure to follow the correct steps during installation, use of inappropriate tools during installation or damage to the bearing during installation may cause problems with the bearing during operation.

5. Improper handling: During the use of the bearing, improper maintenance, incomplete cleaning or failure to replace damaged parts in time may accelerate the damage of the bearing.

6. Harsh working environment: In harsh working environments, such as high temperature, high humidity, corrosive media, etc., the life of the bearing may be shortened.

7. Overload: The bearing is subjected to forces exceeding its design load, which may cause bearing damage.

8. Design or manufacturing defects: Defects in the design or manufacturing process of the bearing may also cause the bearing to be damaged during operation.

To reduce the risk of bearing damage, the following measures can be taken:

1. Select bearings of appropriate types and specifications to meet work requirements.

2. Ensure that the bearings are properly installed and lubricated.

3. Regularly maintain and inspect the bearings and replace damaged parts in a timely manner.

4. Avoid overloading or overusing the bearings.

5. In harsh working environments, take appropriate protective measures, such as adding protective covers, using seals, etc.

The causes of bearing damage may involve multiple aspects, which require comprehensive consideration and appropriate measures to prevent and maintain.
