Determining whether a bearing needs to be replaced usually involves an assessment of bearing performance, wear condition, and overall health. Here are some common ways to tell if a bearing needs to be replaced:

1. Listen to the sound:

If a running bearing makes a sharp hissing sound, a metallic knocking sound, or an irregular noise, it may be a sign of bearing damage or severe wear.

2. Check the temperature:

Use an infrared thermometer or other temperature measuring tool to measure the bearing temperature. If the bearing temperature rises abnormally and exceeds the normal operating temperature range, it may be caused by excessive friction or poor lubrication inside the bearing.

3. Check the vibration:

Use a vibration sensor or vibration analyzer to detect the vibration level of the bearing. Bearing wear or damage usually leads to increased vibration levels.

4. Lubrication condition:

Check the lubrication condition of the bearing, such as the color, texture, and amount of grease. If the grease is severely contaminated, dry, or excessive, it may be a sign that the bearing needs to be replaced.

5. Appearance inspection:

Observe the appearance of the bearing, especially whether the inner and outer rings, rolling elements, and cages have cracks, peeling, wear, or corrosion.

6. Radial clearance measurement:

Use a feeler gauge or special tool to measure the radial clearance of the bearing. If the clearance is too large, it may be a sign of bearing wear or deformation.

7. Usage record:

Check the usage record of the bearing, including installation date, operating time, load conditions, etc. If the bearing is close to or exceeds its expected service life, or the operating time exceeds the manufacturer's recommended replacement cycle, you may need to consider replacing it.

8. Professional evaluation:

In some cases, it may be necessary to ask a professional mechanical engineer or bearing supplier to evaluate the bearing. They can determine whether the bearing needs to be replaced through more precise testing and analysis.

The specific judgment of whether the bearing needs to be replaced also needs to be combined with the actual situation and the specific requirements of the equipment. Zhongda Bearings has been inspected and tested by professional equipment. At the same time, it can manufacture bearings according to customer needs, and there are also professional inspection equipment to help customers with quality inspection.
