As society continues to advance and mechanization becomes more widespread in production, bearings are becoming increasingly essential components in various machines. Their application is expanding rapidly because they can be easily integrated into existing systems without requiring major overhauls. Monitoring the condition of a machine during operation has become a critical task for engineers and operators. Bearings, being the most crucial rotating parts in any machinery, are often the focus of these checks. Proper condition monitoring helps prevent unexpected failures caused by bearing damage, ensuring timely maintenance before serious issues arise. However, not all machines are equipped with advanced diagnostic tools. In such cases, it's vital for operators or maintenance engineers to remain vigilant and pay close attention to subtle signs that may indicate a problem with the bearing. Here are some key points to consider when checking the status of a bearing during operation. One of the most common indicators of abnormal bearing behavior is high temperature. Excessive heat can degrade the lubricant inside the bearing, leading to premature wear. If a bearing operates continuously above 125°C, its lifespan will significantly decrease. High temperatures can result from several causes, including insufficient lubrication, contaminated grease, excessive load, bearing damage, lack of clearance, or oil seal issues. Therefore, continuous temperature monitoring—whether measuring the bearing itself or surrounding components—is essential. Any unusual temperature change could signal an underlying issue. Another important aspect is inspecting the bearing’s sealing system. Ensuring that the oil seals are intact and free from wear is crucial. When opening the bearing housing, visually check the condition of the seals and ensure they are properly lubricated to prevent contaminants like moisture, dust, or corrosive substances from entering. The retaining ring and labyrinth seals should also be greased to maximize protection. If the oil seal shows signs of wear, it must be replaced immediately. A damaged oil seal can allow external contaminants to enter the bearing and cause leaks, which can lead to further damage. Listening for unusual sounds is another effective method for detecting bearing problems. Using an electronic stethoscope, operators can identify irregular noises that may indicate internal damage. A healthy bearing typically produces a smooth humming sound. However, if sharp or irregular noises occur, it may suggest poor lubrication, incorrect clearance, or damage to the outer race. Dents on the bearing’s outer ring can cause vibrations and loud noises. Similarly, knocking sounds from external sources can create noise that varies with the bearing’s speed. Intermittent noises may indicate damage to rolling elements, while the presence of pollutants can cause squeaking. Severe damage may result in loud, unpredictable noises. In summary, regular inspection and monitoring of bearings are crucial for maintaining the efficiency and longevity of mechanical systems. By paying attention to temperature, sealing integrity, and unusual sounds, operators can detect early signs of failure and take preventive action. **Related Bearing Knowledge** - Bearing analysis on skates: Key points in selecting "sliding bearing oil" - Important issues to focus on when storing bearings - KOYO bearing’s exterior and outer layer quality combined with needle roller bearing product density and production requirements This article links to http:// Please indicate the bearing network http:// Previous: Selection and Application of "High-precision SKF Bearings" Next: SKF Imported Bearings Show the Appearance of Pseudo-Brinell Indentation
