From what aspects should bearing performance be evaluated?

1. Listen to the sound:

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

2. Check the temperature:

Use an infrared thermometer or other temperature measurement 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 internal friction or poor lubrication of the bearing.

3. Check vibration:

Use a vibration sensor or vibration analyzer to detect vibration levels in bearings. Worn or damaged bearings often result in increased vibration levels.

4. Lubrication condition:

Check the lubrication condition of the bearing, such as the color, texture and quantity of grease. If the grease is heavily 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 there are cracks, peeling, wear or corrosion on the inner and outer rings, rolling elements and cages.

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 records:

Check the bearing usage records, including installation date, operating time, load conditions, etc. If a bearing is approaching or exceeding its expected service life, or has been operating longer than the manufacturer's recommended replacement interval, replacement may need to be considered.

8. Professional evaluation:

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

Please note that the above method is for reference only. To determine whether the bearing needs to be replaced needs to be combined with the actual situation and the specific requirements of the equipment. Zhongxi bearings have been inspected and inspected by professional equipment. At the same time, we can manufacture bearings according to customer needs. We also have professional inspection equipment to help customers with quality inspection.
