Not all damaged bearings can be repaired, but for each damaged bearing, the cause and extent of damage must be evaluated to avoid or reduce re-damage before considering repairing or replacing a new bearing. There are many reasons for damage to SKF bearings, such as improper installation, dirt intrusion or moisture intrusion, which are common causes of early damage to many SKF bearings. Analysis of common causes of damage to SKF bearings and corresponding precautions that extend the life of SKF bearings.
A. Improper operation:
Improper installation, operation or disassembly may cause deformation or defect of the cage
Precautions: Use appropriate handling, installation and removal tools
B. Insufficient lubrication:
Insufficient or improper lubrication may result in component scratches or severe bearing deformation
Precautions: Improve the lubrication system and properly replenish or replace the lubricant at regular intervals
C. Rusty and corrosion:
Contact with water can cause the bearing components to erode and rust. Bearings after rust damage may cause spalling during work
Precautions: Regularly check the seal to ensure a good sealing effect and properly store SKF bearings
D. Current:
Powering up the bearing as it rotates may result in grooves or nicks. Improper electrical grounding can cause minor burns when the bearing is stationary
Precautions: Reduce or avoid current flow through the bearings by properly grounding the connections before parts other than SKF bearings
E. External materials:
Abrasion particles contamination and debris intrusion may cause wear, abrasion and dents on the SKF bearing face
Precautions: Remove invading particles and debris, replace lubricant, check sealing system
F. eccentric:
Eccentricity, tilting, or excessive loading can cause geometric stress concentrations or surface spalling
