Causes And Maintenance Of Skf Bearing Damage

Causes And Maintenance 

Not all damaged bearings can be repaired, but for each damaged bearing, before considering repairing or replacing a new Causes And bearing, the cause and degree of damage must be evaluated to avoid or reduce further damage.

There are many causes of SKF Bearing Damage, such as improper installation, dirt intrusion or moisture intrusion, which are common causes of early damage of many SKF bearings. Analysis of common damage causes of SKF Bearing and corresponding preventive measures to prolong the service life of SKF Bearing.

A. Improper operation:

Improper installation, operation or disassembly may cause Causes And deformation or damage to the cage

Precautions: use appropriate operation, installation and Causes And disassembly tools

B. Insufficient lubrication:

Insufficient or improper lubrication may result in component scratch or serious bearing deformation

Preventive measures: improve the lubrication system and Causes And supplement or replace the lubricant regularly and properly

C. Rust and corrosion:

Contact with water may cause corrosion and rust of bearing Causes And elements. Rusted and damaged bearings may cause spalling during operation

Preventive measures: check the seal regularly to ensure good Causes And sealing effect, and store SKF bearings correctly

Causes And Maintenance Of Skf Bearing Damage

D. Current:

Energizing the bearing while it is rotating may cause grooves or nicks. When the bearing is Causes And stationary, improper grounding of electrical operation will cause slight burns

Precautions: before welding components other than SKF Causes And bearings, reduce or avoid current passing through the bearings through appropriate grounding connections

E. External materials:

Abrasive particle contamination and debris intrusion may cause wear, scratches and dents on the working surface of SKF Bearing

Precautions: remove invading particles and debris, change lubricant and check sealing system

F. Eccentricity:

Eccentricity, inclination or excessive load may lead to geometric stress concentration or surface spalling

Preventive measures: accurately process SKF bearing seat and shoulder

During the periodic maintenance and operation of SKF Bearing equipment and the replacement of peripheral parts, when the search and inspection of the disassembled bearing is suspended, it is necessary to judge whether the secondary SKF Bearing parts can be reused and record the good or bad application conditions.

Secondly, check the condition of the raceway surface, rolling surface and joint surface of SKF Bearing and the wear condition of the confrontation frame for damage and abnormal conditions. In particular, check the running track of the raceway surface.

To judge whether the bearing can be used again, we should think about the level of bearing damage, mechanical function, priority, operation premise, search and inspection cycle, etc.

The cleanliness of the bearing has a great impact on the service life of Timken bearing. The company has conducted a special test for this purpose, and the result is that the difference is several times or even dozens of times.

The higher the cleanliness of Timken bearing, the longer the service life. The tests of others show that the lubricating oil with different cleanliness has a great impact on the service life of ball bearing.

Therefore, improving the cleanliness of the lubricating oil can prolong the service life of the bearing. In addition, if the dirt particles in the lubricating oil are controlled below 10um, the service life of the bearing will increase several times.

(1) The test results of the company’s test center show that the cleanliness seriously affects the vibration level of the bearing, especially in the high frequency band. The bearing with high cleanliness has low vibration speed, especially in high frequency band.

(2) The influence of dust in bearing grease on noise has been tested. It is proved that the more dust, the greater the noise.

(3) Impact on lubrication performance the decline of the cleanliness of Timken bearing not only affects the formation of lubricating oil film, but also causes the deterioration of lubricating grease and accelerates its aging, thus affecting the decline of lubricating performance of lubricating grease.
