During the use of bearings, there are many forms of failure, which can be classified into four types based on the overall situation: improper assembly, improper lubrication, pollution, and fatigue. What is the proportion of these failure modes when bearings fail? Based on experience, share the approximate proportion of bearing failure forms.

1. Improper assembly -16%
   In general, improper assembly of bearings accounts for 16% of the total, and 16% of premature failures of various bearings are caused by improper assembly (usually due to excessive force…) and improper use of assembly tools. Some devices require the use of mechanical, hydraulic, or heating methods for correct and effective installation and disassembly. Using a complete set of tools and equipment with various professional engineering service technologies to make these tools simple, fast, and more efficient. Using specialized tools and techniques for professional assembly is a solution to maximize machine running time.
2. Improper lubrication -36%
   Improper lubrication of bearings generally accounts for 36%. Although various “maintenance free” sealed bearings can be installed, 36% of premature failures in bearings are still caused by incorrect application and improper use of lubricating grease technology. Any improperly lubricated bearing is inevitably prone to premature failure before its normal service life. Due to the fact that bearings are usually the most difficult components to install and disassemble in mechanical equipment, problems can arise if not lubricated regularly. Develop a fully automatic lubrication system to achieve optimal lubrication performance when manual maintenance is not feasible. As long as high-quality lubricants, tools, and techniques are used for effective lubrication according to requirements, it will help significantly reduce downtime.
3. Pollution -14%
   Bearing contamination generally accounts for 14%. Bearings are precision components, and if the bearings and lubricating grease are contaminated, they will not operate effectively. In addition, due to the fact that maintenance free sealed bearings already filled with grease only account for a small portion of all used bearings, at least 14% of all premature failures in bearings are caused by pollution issues. IMCB has excellent bearing manufacturing and design capabilities and can provide sealing solutions for various harsh working environments.
4. Fatigue -34%
   Bearing fatigue failure generally accounts for 34%. If the machine experiences overload, improper use or maintenance, the bearings will be affected, and 34% of the bearings that fail prematurely are caused by fatigue. Due to improper maintenance or excessive stress, bearings can issue “advance warnings” and can be detected and analyzed using condition monitoring equipment. Therefore, sudden or unplanned failures can be avoided.
