**False Brinell Indentation Damage Condition:** This type of damage occurs during vibration, where the contact between the rolling elements and raceway is affected by oscillations. The damage resembles a Brinell indentation in appearance. **Cause:** During transportation, the SKF bearing may experience small amplitude oscillations when it stops, leading to this kind of damage. **Solution:** Secure the shaft and bearing housing during transport. Separate the inner and outer rings, apply pre-load to reduce oscillation, and use an appropriate lubricant. --- **Creep Damage Condition:** Creep refers to the formation of a gap between the mating surfaces of the bearing. It can result in surface wear, with a shiny or dark appearance. Sometimes, there may be a band-like scratch or wear on the surface. **Cause:** Insufficient interference fit or improper clearance, and the inability to tighten the sleeve properly. **Solution:** Check the interference fit, perform the rotation stop method, ensure proper tightening of the adapter sleeve, and verify the accuracy of the shaft and bearing housing. Apply axial preload and secure the raceway surface. Use bonding agents and anti-slip compounds. --- **Burn Damage Condition:** The raceway, rolling elements, and cage may become overheated during operation, causing discoloration, softening, welding, and eventual damage. **Cause:** Poor lubrication, excessive load or preloading, high speed, small clearance, water or foreign matter intrusion, poor shaft and housing accuracy, or significant shaft deflection. **Solution:** Improve lubrication methods and select the right bearing. Ensure proper clearance and preloading. Enhance sealing systems and check the accuracy of the shaft and housing. Optimize equipment setup. --- **Electro-Erosion Damage:** This occurs when current flows through the bearing during operation, creating sparks across a thin oil film. The surface shows signs of melting and pitting. **Cause:** Potential difference between the inner and outer ring. **Solution:** Avoid having current pass through the bearing during installation. Insulate the bearing if necessary. --- **Rusting and Corrosion Damage:** This includes pit rust, surface rust, and general corrosion on the outer parts of the bearing. **Cause:** Water or corrosive substances (like paint or gas) entering the bearing, improper lubricant, moisture condensation, storage in humid conditions, or inadequate protection during transport. **Solution:** Improve sealing, choose the right lubrication method, apply anti-rust measures when the bearing is not in use, and store the bearing properly. Always handle SKF bearings with care. --- **Equipment Damage Condition:** Axial line-like flaws appear on the raceway and rolling surfaces during operation or disassembly. **Cause:** Misalignment during disassembly, or impact loads when removing the bearing. **Solution:** Use the correct tools to avoid impact loads and ensure alignment during installation and removal. --- **Discoloration Damage Condition:** The raceway, rolling elements, and cage may change color due to heat and lubricant breakdown. **Cause:** Poor lubrication, which leads to hot oil immersion and temperature rise. **Solution:** Improve the lubrication process and ensure proper application techniques. --- **Related Bearing Knowledge:** - Selection of Roller Bearings - Oscillation Inspection of Rolling Bearings - Specifications and Size Selection of Bearings - Selection of Imported Bearings - Six Major Disadvantages of Miniature Bearings - Overview and Usage Instructions for Miniature Bearings This article links to http:// Please indicate China Bearing Network http:// Previous: Bearing Material Without Lubrication (2) Next: Bearing Box Floating Labyrinth Oil Seal
