What's the difference between the high-speed and low-speed bearing, is how to distinguish?

What's the difference between the high-speed and low-speed bearing, is how to distinguish? Today is long seen bearing is very important in the modern industry, and bearing the development of technology also affect some category. We usually see a lot of things, like cars, door by has many categories, such as in the middle of the shaft to assume their use is different, so the classification will be different. You know is there any points of high-speed and low-speed bearing it? It is how to distinguish? Due to the using way is different, so they are low-speed bearing and the bearing of share out bonus. But it is said that they distinguish according to is not the simple from can turn around a few laps. Some low speed of this bearing which speed can reach nearly tens of thousands of revolutions per minute, but some are called high-speed bearing, speed per minute, but several hundred to have. They identify, according to a linear velocity to identify by bearing high linear velocity is high speed bearing. Inside the bearing as the rotation is different also, in the middle of the low speed that it is the main use of circular, cylindrical and conical rotor, the high-speed bearing is bearing shell. On the appearance of it will find high-speed bearing appearance will look a bit more lubrication and appearance there won't be as rough or as low-speed bearing is certainly some pits. The gap between the outer and inner circle is very small, the precision of the bearing also compare high, low speed its appearance will be relatively rough, precision even harsher. On the use of data have some difference. High speed exactly this kind of use are metallurgical, compare with high hardness steel, acceptable compare with big pressure.
