Protect Your Bearings from Wear to Extend Service Life

At Emerson Bearing, we understand that the longevity of your bearings is crucial to the performance and reliability of your machinery. That’s why we’re sharing this guide on bearing wear and service life—so you can maximize the lifespan of your bearings and avoid costly downtime. **What is Wear?** Wear in a rolling bearing occurs when material is removed from the contact surfaces due to friction or external factors. The extent of this wear depends largely on the environment and operating conditions the bearing is subjected to. Common causes include dirt and contaminants entering the bearing, inadequate lubrication, lubricant degradation, moisture-induced corrosion, exposure to corrosive substances, and aggressive EP (extreme pressure) additives in some lubricants. **Why Should You Care About Wear?** Wear can significantly impact the performance and lifespan of your bearings. It can increase noise levels, cause abnormal clearances, and reduce the accuracy of the machine it’s part of. If left unchecked, wear can escalate into a serious issue, eventually leading to complete failure. Early signs of wear may include scratched raceways, unusual running noises, or a dull appearance on the contact surfaces. **How Can You Minimize Wear?** The best way to reduce wear is to maintain proper lubrication and keep the bearing as clean as possible. Avoiding contamination and exposure to harsh elements can go a long way in preserving your bearings. When a bearing is well-lubricated, properly sealed, and kept free from excessive loads, it can operate for a long time without significant wear. However, in certain environments—such as those with high dust, moisture, or chemical exposure—it may be more cost-effective to replace a worn bearing than to constantly try to maintain it. Regular inspections and timely replacements are key to preventing unexpected failures. If you're unsure about the condition of your bearings, it's always a good idea to consult an expert.
