Bearing damage caused by many reasons, such as improper installation, dirt intrusion or water intrusion is a common cause of plane thrust ball bearings early damage. Bearing a common cause of damage analysis and the corresponding preventive measures to extend bearing life.
Improper operation: installation, improper operation or demolition may be caused by cage deformation or defect.
Inadequate lubrication: lubrication is inadequate or inappropriate may result in components abrasions or serious bearing deformation
Rust and corrosion: contact with water may cause the plane thrust ball bearing element erosion and rust. Bearing corrosion damage at work may lead to spalling
Current: the bearing rotation when power may lead to a groove or notch. The rest of the bearing, the electrical operating Improper grounding can cause minor burns.
External materials: wear particle contamination and debris intrusion may result in the plane thrust ball bearings face wear and tear, scratches and dents.
Eccentric: eccentric, inclined or too heavy load may cause the geometric stress concentration or surface spalling
Troubleshooting. Replacement of the front plane of the thrust ball bearings and grease, adjust the bearing clearance and axial clearance is 0.003mm, radial clearance disabilities 0.002mm; homemade simple research with hand-grinding bearings taper positioning surface, the coloring method to check ensure that the knife handle and bearings centering the tapered bore of the contact area is greater than 85%; replace the disc spring. Replace the repaired bearing bearing box with a dial indicator to check runout, the proximal smaller than 0.006mm, 150mm at the remote is less than 0.010mm. Trial processing, bearing temperature and noise is normal, the machining accuracy to meet the processing requirements, troubleshooting.
