Why is the bearing prematurely damaged? How to improve the life of bearings?

The number of revolutions or hours experienced by a bearing before pitting occurs under a certain load is called bearing life. Bearings within this life should be subject to initial fatigue damage on any of their bearing rings or rolling elements. However, in our daily practical use, it can be clearly observed that the bearing with the same appearance under the same working conditions has a very different actual life. What caused this? Xiaobian summed up the following points:

First, improper installation (about 16%)

1, the installation is too strong, which hit the bearing with a hammer on the bearing damage is the biggest; is also the main cause of deformation.

2. The installation is biased or not installed in the bearing position, resulting in too small bearing clearance. The inner and outer rings are not at the same center of rotation, causing disagreement.

Recommendation: Select an appropriate or professional bearing installation tool, and use a special instrument to detect it after installation.

Second, pollution (about 14%)

Contamination can also lead to premature bearing damage, which means that dust, metal chips, etc. enter the bearing. The main reasons include: opening the bearing packaging too early before use, causing pollution; the working environment is not clean during installation, causing pollution; the working environment of the bearing is not clean, and the working medium is polluted.

Recommendation: It is best not to disassemble the bearing before use; keep the installation environment clean during installation, clean the bearing to be used; and strengthen the bearing seal.

Third, poor lubrication (about 50%)

According to the survey, poor lubrication is one of the main causes of premature bearing damage. Including not adding lubricant or lubricating oil in time; lubricant or lubricating oil is not filled in place; improper selection of lubricant or lubricating oil; incorrect lubrication method, etc.

Recommendation: Choose the right lubricant or lubricant and use the correct lubrication method.

The cause of the heat of the centrifuge motor bearing

First, it may be due to overload or overload, it may be a problem such as a cooling fan, and it may be due to the heat generated by mechanical friction, but the main problem is whether the bearing can be authentic, and some users set low prices for low prices. The bearing, which causes the bearing to heat up, is hot, so that the bearing burns and the like. Therefore, we first emphasize the need to buy authentic (imported) bearings.

Second, we must pay attention to the mechanical lubrication, the selection of high-quality high-temperature lithium grease, the difference between lithium-based grease is another major cause of bearing heat. In addition, you should check with your meticulous situation, assuming that the mechanical friction will be accompanied by noise, and the mechanical parts will have obvious wear. If the bearing is loose, then the bearing should be in a problem and the bearing needs to be changed. It is recommended to purchase authentic imported bearings.

Centrifuge is a high-speed chemical equipment. High-speed bearings are required for good bearings. High-quality and authentic bearings can ensure the long-term normal operation of the centrifuge, and the service life can last for more than 10 years.

Third, the concentricity of the centrifuge spindle can be accurate. Under normal circumstances, people pay less attention to the concentricity. The tendency of the spindle concentricity is very easy to form the bearing heat.
