One, improper installation (about 16%)
Improper installation is one of the most common causes of bearing failure. Around 16% of issues stem from incorrect handling during the installation process. A major mistake is using brute force, such as hitting the bearing directly with a hammer, which can cause severe internal damage and lead to deformation. This not only reduces the bearing's lifespan but also compromises its performance.
Another issue is when the bearing is not properly aligned or seated in the correct position. If the installation is off-center or incomplete, it can result in excessive clearance or misalignment between the inner and outer rings. This misalignment causes uneven stress distribution and can lead to premature wear or even complete failure.
Recommendation: Always use the appropriate installation tools designed for bearings and ensure proper alignment. After installation, it’s important to inspect the bearing using specialized instruments to confirm everything is functioning correctly.
Second, fatigue (about 34%)
Fatigue damage is the most common type of failure in SKF bearings, accounting for around 34% of all issues. This occurs due to repeated stress over time, especially when the bearing is subjected to long-term overload conditions. Bearings that are consistently overworked without adequate cooling or lubrication are more prone to fatigue.
In addition, neglecting regular maintenance or performing it incorrectly can accelerate the onset of fatigue. Poor maintenance practices, such as failing to replace worn components or not following manufacturer guidelines, can significantly shorten the life of a bearing. Equipment aging is another contributing factor—over time, even well-maintained bearings will eventually show signs of wear due to continuous operation.
Third, contamination (about 14%)
Contamination is another significant cause of bearing failure, responsible for about 14% of problems. Contaminants like dust, dirt, metal shavings, or moisture can enter the bearing and cause serious damage. These particles can interfere with the smooth rotation of the bearing, leading to increased friction, overheating, and eventual failure.
Common sources of contamination include opening the bearing packaging too early before installation, which exposes it to environmental pollutants. Poor working conditions during installation or operation can also introduce contaminants. Additionally, if the surrounding environment is not clean or the lubricant is not properly maintained, the bearing can become contaminated over time.
To prevent contamination, always keep the installation area clean, use protective packaging until ready for use, and ensure that the lubricant is free from impurities. Regular inspections and proper sealing mechanisms can also help protect the bearing from harmful contaminants.
