Rolling bearings are widely used in rotating machinery and are also one of the vulnerable components. Many failures of rotating machinery are related to rolling bearings. The working quality of the bearing has a great influence on the working state of the machinery...

If the bearing is in a good continuous rotation state, it will emit a low whining or buzzing sound. Sharp hissing, squeaking and other irregular sounds often indicate that the bearing is in poor continuous rotation. High-pitched creaking noises can be ...

Grinding is a common method of metal cutting in the machinery manufacturing industry. It is also widely used in the bearing processing industry. The bearing parts that have been heat-treated and quenched may appear mesh-shaped cracks or...

Generation of vibrations in bearings Generally speaking, rolling bearings do not generate noise by themselves. What is commonly perceived as "bearing noise" is actually an acoustic effect in which the bearing vibrates directly or indirectly ...

At present, the internal structure parameters of bearings in my country are almost the same as those of advanced foreign companies. However, the vibration and noise levels of such products in my country are far from ...

Rolling bearings may be damaged due to various reasons during operation, such as improper assembly, poor lubrication, moisture and foreign body intrusion, corrosion and overloading, etc., which may lead to premature bearing damage....
