Causes and prevention techniques of wear of double row deep groove ball bearings

The amount of material loss due to wear is called wear. This can be obtained by measuring changes in length, volume, or mass and calling them line wear, volume wear, and mass wear accordingly.
The use factors of double row deep groove ball bearings mainly refer to whether the installation and adjustment, use and maintenance, maintenance and repair meet the technical requirements. According to the technical requirements of bearing installation, use, maintenance and maintenance, the load, speed, working temperature, vibration, noise and lubrication conditions borne by the bearing in operation are monitored and checked, and if any abnormality is found, the cause is immediately found and the adjustment is made to restore it to normal. Installation conditions are one of the primary factors in the use of bearings, bearings often due to improper installation and lead to changes in the stress state between the whole set of bearing parts, bearings in the abnormal state of operation and early end of the service life of the internal factors mainly refers to the structural design, manufacturing process and material quality to determine the quality of double row deep groove ball bearings three factors.

1. Improper use of bearings.
   Cause: Improper installation, operation or disassembly may cause deformation or defect of the cage
   Recommendation: Use appropriate tools for operation, installation, and removal
2. Inadequate lubrication
   Cause: Inadequate or improper lubrication may lead to component abrasion or serious deformation of double row deep groove ball bearings
   Suggestion: Improve the lubrication system, replenish or replace the lubricant properly
3. Rust and corrosion
   Cause: Contact with water may lead to corrosion and rust of the shaft bearing element of the pump. The double row deep groove ball bearing after corrosion damage may lead to peeling during operation
   Suggestion: Check the seal regularly to ensure good sealing effect and store imported bearings correctly
4. Current
   Cause: Electric power during rotation may cause grooves or nicks. When double row deep groove ball bearings are at rest, improper grounding of electrical operation can lead to minor burns
   Recommendation: Reduce or avoid current passing through the bearing by proper grounding connections before welding components other than the bearing
5. External materials
   Cause: Wear particle contamination and debris intrusion may lead to wear, abrasion and depression of the imported bearing working face
   Recommendation: Remove intrusive particles and debris, change lubricant, check sealing system
6. Eccentricity
   Cause: Eccentricity, tilt, or excessive loading may lead to geometric stress concentration or surface spalling
   Suggestion: Accurate processing of imported bearing housing and blocking shoulder
   After the installation of double row deep groove ball bearings, in order to check whether the installation is correct, to carry out operation inspection. Small machines can be rotated by hand to confirm smooth rotation. Check items due to foreign bodies, scars, indentation caused by poor operation, due to poor installation, poor processing of the installation seat torque instability, due to too small clearance, installation error, sealing friction caused by the moment is too large and so on. If there is no abnormality, power operation can be started.
