There are many causes of bearing damage, such as improper installation, dirt intrusion or moisture intrusion, which are common causes of early damage to many imported bearings. Not all damaged imported bearings can be repaired, but for each damaged inlet bearing, the cause and extent of damage must be evaluated to avoid or reduce re-damage before considering repairing or replacing a new bearing. The following are some common causes of damage to large-size imported bearings and the corresponding precautions to extend the life of imported bearings.

A. 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 lubrication Or improper use 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. Rusting and Corrosion

Contact with water may cause corrosion and rusting of the shaft components. Bearings after corrosion damage may cause spalling precautions during work, regular inspection of seals, good sealing effect, proper storage of bearings D. Current

Energization of imported bearings when rotating may cause grooves or nicks . Improper grounding of the electrical drive when the bearing is stationary can result in minor burn precautions. Reduce the current flow through the bearing by appropriate grounding connections before welding the components outside the bearing. E. External material

Abrasion particles and debris Intrusion may lead to wear and tear on the working face of the bearing, scratches and dents, remove invading particles and debris, replace the lubricant, check the sealing system F. Eccentricity

Eccentricity, tilt or excessive load may cause geometric stress Concentration or surface peeling
