Rolling bearings are essential components in many mechanical systems, and their longevity depends heavily on proper maintenance and correct usage. However, various factors such as improper operation, inadequate lubrication, rust, electrical currents, contamination, and mechanical stress can significantly reduce their lifespan. To ensure optimal performance and extend the service life of bearings, it is crucial to understand and implement preventive measures.
**A. Insufficient Lubrication**
Lack of proper lubrication or using the wrong type of lubricant can lead to scratches, wear, and even deformation of bearing components. To prevent this, ensure that the lubrication system is well-maintained, and regularly check, replenish, or replace the lubricant as needed.
**B. Non-Standard Operation**
Improper assembly, operation, or disassembly can cause damage to the cage or other internal parts. Always use appropriate tools and follow manufacturer guidelines. It's also recommended to use genuine bearings from trusted brands like Beijing Derui to ensure quality and reliability.
**C. Rust and Corrosion**
Exposure to moisture or water can cause rust and corrosion, which may result in component failure during operation. Regularly inspect the seals, maintain good sealing conditions, and store bearings in a dry environment to avoid such issues.
**D. Electrical Current Damage**
Electrical currents passing through the bearing can cause grooves or small burns. This often happens when welding or working with electrical equipment. To prevent this, make sure all components are properly grounded before performing any electrical work, and avoid allowing current to pass through the bearing.
**E. Contamination by Particles**
Dust, debris, or foreign particles can enter the bearing and cause wear, scoring, or damage to the raceways. Prevent contamination by maintaining clean environments, replacing lubricants regularly, and checking the integrity of the sealing system.
**F. Mechanical Stress and Misalignment**
Overloading, misalignment, or improper installation can create stress points within the bearing, leading to premature failure. Ensure that the housing and shaft are machined accurately, and avoid excessive loads or misalignment during installation.
