At Emerson Bearing, we understand that the longevity of your bearings plays a crucial role in the performance and reliability of your machinery. That’s why we’re here to help you extend the service life of your bearings and avoid premature failure. This article will explore what bearing wear is, why it matters, and how you can take steps to reduce it and keep your equipment running smoothly.
**What is Wear?**
Wear in rolling bearings refers to the gradual loss of material from the contact surfaces due to friction and other external factors. The extent of wear depends largely on the operating conditions and environment the bearing is exposed to. Common causes include contamination from dirt and foreign particles, inadequate or poor-quality lubrication, lubricant breakdown, moisture-induced corrosion, exposure to corrosive substances, and aggressive extreme pressure (EP) additives in lubricants.
**Why Should You Be Concerned About Wear?**
Wear doesn’t just shorten the life of your bearings—it also affects the overall performance of your machine. As wear progresses, it can lead to increased noise, higher vibration, and greater clearance, all of which can reduce accuracy and efficiency. If left unchecked, this process can escalate into a chain reaction, eventually leading to complete bearing failure. Early signs of wear may include scratched raceways, unusual noises during operation, or a dull, worn appearance on the bearing surfaces.
**How Can You Minimize Bearing Wear?**
The best way to prevent excessive wear is to maintain proper lubrication and keep the bearing as clean as possible. Ensuring that your bearings are well-sealed and protected from contaminants can significantly reduce the risk of damage. When bearings are properly lubricated, kept clean, and not overloaded, they can operate for extended periods without significant wear.
However, in some applications, maintaining cleanliness or avoiding corrosive elements can be challenging. In such cases, it might be more cost-effective to replace a worn bearing rather than continuously try to maintain it. It's always better to replace a bearing before it fails completely to avoid unexpected downtime and costly repairs.
When severe wear occurs, it’s important to calculate the fatigue life using established methods like Eschmann’s estimation procedure. This helps ensure accurate predictions and informed maintenance decisions.
