During the use of bearings, there are many kinds of failure forms. From the overall situation, the failure forms of bearings can be divided into four types: improper assembly, improper lubrication, pollution and fatigue. When the bearing fails, what is the proportion of these failure modes? Learn from experience and share the approximate proportion of bearing failure forms.

1. Improper assembly - 16%

In general, improper assembly of bearings accounts for 16%, and 16% of premature failure of various bearings is due to improper assembly (usually due to excessive force...) And incorrect use of assembly tools. Some equipment requires correct and effective installation and disassembly by mechanical, hydraulic or heating methods. The use of a full set of tools and equipment of various professional engineering service technologies makes these tools simple, fast and more profitable. Using special tools and technologies for professional assembly is a solution to maximize the running time of the machine.

2. Improper lubrication - 36%

The improper lubrication of bearings generally accounts for 36%. Although various "maintenance free" sealed bearings can be installed, 36% of the early failure bearings are still caused by incorrect technical application and improper use of lubricating grease. Any bearing with improper lubrication will inevitably fail ahead of its normal service life. Since the bearing is usually the most difficult part of mechanical equipment to load and unload, problems will occur if it is not lubricated frequently. When manual maintenance cannot be achieved, a fully automatic lubrication system is developed to achieve the best lubrication effect. As long as high-quality grease, tools and technology are used for effective lubrication according to requirements, it will help to significantly reduce downtime.

3. Pollution - 14%

Bearing pollution generally accounts for 14%. The bearing is a precision part. If the bearing and grease are contaminated, they will not operate effectively. In addition, maintenance free sealed bearings that have been filled with grease only account for a small part of all bearings used, so at least 14% of all bearings that fail early are caused by pollution. SKF 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 is overloaded, used or maintained improperly, the bearings will be affected. 34% of the bearings that lead to premature failure are caused by fatigue. Because the bearing will give "advance warning" in case of improper maintenance or excessive stress, the condition monitoring equipment can be used for detection and analysis, so sudden or unplanned failure can be avoided.
