Causes and Preventive Techniques of Wear of Double Row Deep Groove Bearings

The use factor of double row deep groove bearing mainly refers to whether the installation adjustment, use and maintenance, maintenance and repair, etc. 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 running bearing, find the cause immediately, and make adjustments to make it Back to normal. The installation condition is one of the primary factors in the use factor. The double row deep groove bearing often changes the stress state between the parts of the whole set of bearings due to improper installation. The bearing runs in an abnormal state and ends its service life early. The internal factors are mainly It refers to the three major factors that determine the quality of double row deep groove bearing, such as structural design, manufacturing process and material quality.

1. Improper use of double row deep groove bearing .

Reason: improper installation, operation or disassembly may cause deformation or defect of the cage

Recommendation: Use suitable handling, installation and removal tools

2. Insufficient lubrication

Reason: Insufficient or improper lubrication may cause galling of components or severe deformation of double row deep groove ball bearing.

Suggestion: Improve the lubrication system, replenish or replace the lubricant regularly and properly

3. Rust and Corrosion

Cause: Contact with water may cause corrosion and rust of the shaft-connected bearing elements of the pump. Double row deep groove ball bearing damaged by rust may cause spalling during operation

Recommendation: Check the seal regularly to ensure good sealing effect and store imported bearings correctly

4. Current

Cause: Turning on power may cause grooves or nicks. Improper grounding of electrical operations can cause minor burns when the double row deep groove ball bearing is stationary

Recommendation: Reduce or avoid current flow through the bearing by appropriate ground connections before welding on components other than the bearing

5. External materials

Cause: Abrasive particle contamination and debris intrusion can cause wear, galling, and denting of inlet bearing surfaces

Recommendations: Remove invading particles and debris, change lubricant, check sealing system

6. Eccentric

Cause: Eccentricity, tilting or excessive loading may cause geometric stress concentration or surface peeling

Recommendation: Precise machining of imported housings and shoulders

After installation of double row deep groove bearing, in order to check whether the installation is correct, a running inspection is required. Small machines can be rotated by hand to confirm that they rotate smoothly. The inspection items include sluggish operation caused by foreign objects, scars and indentations, unstable torque caused by poor installation and poor processing of the mounting seat, excessive torque caused by too small clearance, installation error, and sealing friction, etc. Wait. If there is no abnormality, the power operation can be started.
