Double row deep groove ball bearing wear prevention

Due to wear caused by the amount of material loss referred to wear. This can be by measuring the length, volume, or mass to obtain the change, and accordingly they are called wire wear
Volume, the volume and quality of wear wear.

   Double row deep groove ball bearing mainly refers to installation and adjustment factors, use and maintenance, repair and other maintenance meets the technical requirements. According bearing installation, use, maintenance
Care and maintenance of the technical requirements for the operation of the bearings to withstand load, speed, temperature, vibration, noise and lubrication condition monitoring and inspection, hair
Are abnormal immediately find reasons to adjust it back to normal. Installation conditions are the primary factors that one of the factors bearing is often caused by improper installation
Resulting package bearing between the various parts of the stress state changes, bearing in abnormal state of operation and early life of the inner end of the main factors is the knot
Structural design, manufacturing processes and materials quality double row deep groove ball bearings determine the quality of three major factors.

1 improper use bearings.

Cause: The installation, operation, or improper removal may cause deformation or defect in the cage

Recommendation: Use the appropriate operating, installation and removal tool

(2) inadequate lubrication

Reasons: inadequate or improper lubrication may cause abrasions or serious element of the double row deep groove ball bearing deformation

Recommendation: Improved lubrication system, aptly timed to supplement or replace the lubricant

3 rust and corrosion

Cause: Contact with water may cause water pump bearing element pitting and rusting. Rust after injury double row deep groove ball bearings at work may cause spalling

Recommendation: regularly check seals to ensure good sealing effect, correct storage of imported bearings

4 Current

Cause: The rotation is powered may cause grooves or nicks. Double row deep groove ball bearing is stationary, electrically operated Improper grounding can cause minor burns

Recommendation: In the outside of the bearing parts before welding through proper ground connection to reduce or avoid the current through the bearing

5 External materials

Cause: The abrasive particle contamination and debris intrusion may lead bearings face wear, abrasions and depression

Recommendation: Clear intrusive particles and debris, replace the lubricant, check the sealing system

6. Eccentric

Reason: eccentric, inclined or excessive load may result in geometric stress concentration or flaking

Recommendation: precision machining imported bearing and retaining shoulder

Double row deep groove ball bearings after installation, in order to check for proper installation, operation should be checked. Small machines can be rotated by hand to confirm whether the rotation along
Cheong. Check the project due to nick, indentation caused by dysfunctional, because poor installation, mount the torque generated by poor processing unstable, due Tour
Gap is too small, the installation error, caused by seal friction torque is too large and so on. Without exception, you can begin powering.
