KM double row deep groove ball bearing wear causes and prevention techniques, let's learn

The amount of material lost due to wear is called wear. This can be obtained by measuring changes in length, volume, or mass, and they are accordingly called line wear, volume wear, and mass wear.
The use factor of double row deep groove ball bearing mainly refers to whether the installation adjustment, use maintenance, maintenance and repair meet the technical requirements. According to the technical requirements of bearing installation, use, maintenance and maintenance, monitor and check the load, speed, working temperature, vibration, noise and lubrication conditions of the bearing in operation, find out the reason immediately when abnormal is found, and make adjustment to make it back to normal. Installation condition is one of the primary factor of use factor, bearing is often caused by improper installation of a complete set of change the stress of bearing between various parts, bearing in the abnormal state of operation and the service life of the early end internal factors mainly refers to the structure design, manufacturing process and material quality in determining the quality of double row deep groove ball bearings, such as the three major factors.
1. Improper operation of bearings.
Cause: Improper installation, operation or disassembly may cause deformation or defect of the retainer
Recommendation: Use appropriate operation, installation, and disassembly tools
2. Insufficient lubrication
Cause: Inadequate or improper lubrication may result in component abrasion or severe deformation of double row deep groove ball bearings
Recommendations: Improve the lubrication system, timing and appropriate replacement or lubricant
Harbin bearing
Rust and corrosion
Cause: Contact with water may cause corrosion and rust of pump shaft bearing elements. The double row deep groove ball bearings after rust damage may cause spalling during operation
Suggestion: check the sealing regularly to ensure good sealing effect and store the imported bearings correctly
4. The current
Reason: The electrification during rotation may cause grooves or nicks. Improper electrical grounding of a double row deep groove ball bearing at rest can cause minor burns
Recommendation: Reduce or prevent current from passing through the bearing by proper grounding connections before welding on parts other than the bearing
5. External materials
Cause: Abrasive particle pollution and debris intrusion may cause wear, abrasions and dents on the working face of the imported bearing
Recommendations: Remove intrusive particles and debris, replace lubricants, and check the sealing system
Eccentric 6.
Cause: Eccentricity, tilt, or excessive load may result in geometric stress concentration or surface peeling
Recommendation: Precision machining of import bearing and shoulder block
After the installation of double row deep groove ball bearings, operation inspection shall be carried out to check whether the installation is correct. Small machines can be rotated by hand to ensure smooth rotation. Inspection items due to foreign bodies, scars, indentation caused by the operation of the unstable moment due to poor installation, poor processing of the installation seat due to torque instability due to too small clearance, installation error, sealing friction caused by excessive torque, etc. If there is no abnormality, power operation can be started.
