In ordinary use, vibration damage to bearings is quite sensitive, spalling, indentation, corrosion, cracks, wear and so on will be reflected in the bearing vibration measurement. Therefore, the magnitude of vibration can be measured through...

Roundness measurement is critical for many applications. It can be measured in several different ways, ranging from simple caliper measurements to high-precision, dedicated roundness measurement systems. In this article...

For each bearing, there is its own limit rotational speed, bearing speed is mainly by the bearing internal friction heat caused by the temperature rise of the limit, when the rotational speed exceeds a certain limit, the bearing will be due to burns...

Samples should be representative. The results of the samples are used to illustrate the overall picture and to draw conclusions about the overall picture. Sampling is guided by the following principles,Sampling should pay special attention to overcome and eliminate...

The large size of large rolling bearings brings a series of problems in manufacturing, mounting, operation and maintenance: lack of systematic design and manufacturing technology, design and manufacturing accuracy is not easy to ensure, heat treatment difficulties...
