What are the fault diagnosis and maintenance methods of ball bearings?

1. Abnormal noise: Abnormal noise from ball bearings may be caused by damage, wear or insufficient lubrication of internal parts of the bearing. Normal operation of bearings should be smooth and quiet. If you hear squeaking, grinding, or chattering from the bearings, there may be a problem. When abnormal noise is detected, the equipment should be stopped immediately and the bearings should be inspected to determine whether repair or replacement is needed.

2. Vibration: Abnormal vibration is another indicator of bearing problems. If the bearings are in good condition, they should keep running smoothly and reduce the transfer of vibration into the equipment. Abnormal vibrations may indicate that the bearings are worn, unbalanced, or incorrectly installed. Using vibration detection instruments can help identify the source and extent of vibration so that appropriate maintenance measures can be taken.

3. Temperature increase: Abnormal increase in ball bearing temperature may be caused by increased friction, insufficient lubrication or other problems. During use, the surface temperature of the bearings should be checked regularly. High temperatures can cause bearing materials to soften, lubricants to fail, or seals to become damaged. Therefore, once abnormal bearing temperatures are discovered, the equipment should be stopped immediately and the bearings should be inspected to determine the cause.

4. Lubrication problem: Good lubrication is one of the key factors to maintain stable bearing operation. Insufficient or excessive lubrication can have a negative impact on bearings. Check the lubrication condition regularly to ensure the cleanliness and appropriate amount of lubricating grease. Selecting the appropriate grease and proper lubrication method is critical to bearing life and performance.

5. Sealing issues: The sealing components of bearings help prevent external contaminants from entering the interior of the bearing while reducing the loss of lubricating grease. Check whether the bearing seal is intact and ensure its sealing performance is good. Damage or aging of seals may cause bearing failure, so damaged seals should be replaced in time.

6. Bearing wear: Ball bearing wear may lead to bearing failure and equipment shutdown. Regularly inspect the appearance and surface of the bearings to look for any obvious wear, cracks or damage. Prompt detection and replacement of worn bearings can prevent further damage and costs.

7. Regular lubrication: Ball bearings require regular lubrication to reduce friction and wear. Develop an appropriate lubrication plan and select the appropriate lubricant based on the manufacturer's recommendations and the bearing's service conditions. Regularly adding or replacing lubricant can keep the bearings in good condition and extend their service life.

8. Correct installation and alignment: Correct installation and alignment are critical to the normal operation of the bearing. Make sure the bearings are installed in the correct location and that there is adequate alignment and clearance between the shaft and bearings. During installation, follow the installation instructions provided by the manufacturer and use appropriate tools and equipment.

9. Regular maintenance: Perform regular maintenance of ball bearings, including cleaning, lubrication and inspection. Regular maintenance can extend the service life of bearings and reduce the likelihood of failure. According to the use conditions and working environment of the bearing, formulate corresponding maintenance plans and ensure regular execution.

635-Super quiet, high precision, long life deep groove ball bearings
Deep groove ball bearings are widely used bearing type and are particularly versatile. They have low friction and are optimized for low noise and low vibration which enables high rotational speeds. They accommodate radial and axial loads in both directions, are easy to mount, and require less maintenance than other bearing types.
