Understanding the life of a bearing is crucial for maintaining machinery efficiency and avoiding unexpected failures. Bearings have different types of life, each representing a specific stage before they no longer function properly. 1. **Fatigue Life**: This refers to the number of cycles or hours a bearing can operate before the primary moving parts reach their failure limit. It is typically calculated based on the dynamic load it can handle. For example, at 10,000 rpm, a bearing can withstand a certain amount of load before fatigue sets in. - **Additional Dynamic Load**: The maximum load a bearing can take under continuous operation. - **Equivalent Dynamic Load**: A calculated value that represents the actual load a bearing experiences, adjusted for operating conditions. 2. **Wear Life**: This is the period during which the bearing operates due to normal wear. As time passes, the internal clearance increases until it reaches a point where the bearing can no longer perform effectively. In modern manufacturing, this is often the most common type of life, although in some applications like traction motors, the opposite may occur. 3. **Fault Life**: This refers to the time before a bearing loses its functional capacity due to internal damage or defects. Faults can arise from improper installation, incorrect lubrication, or contamination. 4. **Service Life**: This is a general term that combines the above three types of life. In theory, it refers to the fatigue life of the bearing. Under normal conditions, it's usually the wear life, but if the operating conditions are not ideal, it might indicate early failure.
