Improvement Measures to Prevent Damage of Plane Thrust Ball Bearing

  • There are many causes of bearing damage, such as improper installation, dirt intrusion or moisture intrusion, which are the common causes of early damage of many planar thrust ball bearings. Analysis of common damage causes of bearings and corresponding preventive measures that can prolong the service life of bearings
  • Improper operation: improper installation, operation or disassembly may cause deformation or damage to the cage.
  • Insufficient lubrication: insufficient or improper lubrication may lead to component scratch or serious bearing deformation.
  • Rust and corrosion: contact with water may cause corrosion and rust of plane thrust ball bearing elements. Rusted and damaged bearings may cause spalling during operation
  • Current: energizing the bearing while rotating may cause grooves or nicks. When the bearing is stationary, improper grounding of electrical operation will cause slight burns.
  • External materials: abrasive particle contamination and debris intrusion may cause wear, scratches and dents on the working surface of planar thrust ball bearings
  • Eccentricity: eccentricity, inclination or excessive load may lead to geometric stress concentration or surface spalling
  • Troubleshooting. Replace the front plane thrust ball bearing and grease, and adjust the bearing clearance. The axial clearance is 0.003mm and the radial clearance is 0.002mm; Self made simple grinding tool, manually grind the positioning surface of the inner conical hole of the bearing, and check with the coloring method to ensure that the contact area between the tool handle and the bearing centering conical hole is greater than 85%; 
  • Replace the Belleville spring. Install the repaired bearing back into the bearing housing and check the radial runout with a dial indicator. It is less than 0.006mm at the proximal end and less than 0.010mm at 150mm at the distal end. During the trial processing, the temperature rise and noise of the bearing are normal, the processing accuracy meets the processing process requirements, and the fault is eliminated.

Improvement Measures to Prevent Damage of Plane Thrust Ball Bearing

  • ① Add compressed air fine filtration and drying devices. The filter shall be drained regularly, and the filter element shall be cleaned or replaced regularly;
  • ② Check the cleaning and matching condition of the taper hole and knife handle of the plane thrust ball bearing at any time, and check whether the air dryer works normally;
  • ③ Reasonably arrange the processing technology to avoid the sudden change of material removal rate;
  • ④ Overload operation is strictly prohibited. In case of failure, it shall be reported for repair in time. It is not allowed to operate with disease.Improvement Measures to Prevent Damage of Plane Thrust Ball Bearin
