1. What is SKF self-aligning ball bearing? SKF self-aligning ball bearings are bearings with spherical balls installed between the outer rings of the raceway spherical surfaces of the inner ring boxes of the two raceways. The outer diameter of the self-aligning functional bearing and the inner diameter of the bearing seat are sp...

As we all know, the SKF brand is very famous in the bearing industry, but we must pay attention to many details, especially the selection of anti-rust grease is very important, and the implementation of anti-rust technology also affects the quality of SKF bearings. In practical applications, it is often encountered that the use ...

The requirements of centrifugal compressors for bearings are safe and reliable, stable operation, good vibration resistance and long service life. At present, most of the bearings used in domestic centrifugal compressors are dynamic pressure sliding bearings lubricated by high-speed light-load fluids. There are two types of bear...

Many failures of machinery are related to the rolling bearings in rotation. The operation of the bearings has a great impact on the working state of the machinery. Its defects will cause abnormal vibration and noise of the equipment, and even damage the equipment in severe cases. Many mechanical failures are related to the rolli...

The generation of vibration in SKF bearings Generally speaking, rolling bearings themselves do not generate noise. The bearing noise usually felt is actually the sound effect of the bearing directly or indirectly vibrating with the surrounding structure. This is why many times the noise problem can be regarded as a vibration pro...

The intrinsic noise of FAG bearings is the noise that occurs even if the bearings are manufactured using modern processing technology, and the structure of FAG bearings itself is determined. Intrinsic noise can be divided into three types: raceway sound, impact sound of rolling body and rolling sound, which are described as foll...

For each bearing, it has its own limit speed, and the speed plays a key role in the bearing heating factor. If the speed of a bearing exceeds the limit speed, it will cause the bearing temperature to rise, the lubricant will dry, or even Stuck the bearing. Therefore, we are rotating the appropriate bearing type according to the ...

A shaft often requires two fulcrums, that is, two sets of rolling bearings for support. The bearing configuration just solves the problem of how the bearing on the fulcrum fixes the shaft system axially, and how to avoid the bearing from jamming after thermal expansion. Based on the understanding of bearing knowledge, we share t...

1. Selection of shaft and bearing and tolerance of control room Press-in bearings FAG bearings should have no blocks and flexible rotation direction. If the rotation is significantly inflexible, the size of the shaft is too large, and the tolerance drops. As the tolerance of the shaft is obviously sandy after turning the shaft b...
