Proper bearing installation is essential for optimal performance and longevity. Common mistakes include using excessive force, which can damage internal components, and neglecting cleanliness, as contaminants like dirt can lead to failure. Over-lubrication is another issue, as too much lubricant causes overheating and friction, while improper alignment results in uneven load distribution and increased vibration. To avoid these problems, it’s important to use the right tools, maintain a clean environment, apply the correct amount of lubrication, and ensure proper alignment. Following these steps ensures smooth operation and extends bearing life.
