Bearings are important components in modern industry, and their performance technology directly affects the development of certain fields. In daily life, we also constantly come into contact with bearings, such as those needed in automobiles and mechanical equipment, in order to achieve better operation. Because bearings are used in different fields, their classification may also vary. Do you know that bearings can also be divided into high-speed and low-speed? So how do you distinguish between high-speed bearings and low-speed bearings? What is the basis for it? Below are the distinguishing criteria and differences between high-speed bearings and low-speed bearings.

The distinction between high-speed bearings and low-speed bearings is based on:

Due to the different ways of use, bearings can be divided into high-speed bearings and low-speed bearings. However, although this is said, their differentiation is not simply based on how many revolutions can be made per revolution. Some low-speed bearings can reach speeds of nearly tens of thousands of revolutions per minute, while others, although called high-speed bearings, only have a few hundred revolutions per minute. Their differentiation is based on the linear speed of the bearings. Those with high linear speed are high-speed bearings, while those with low linear speed are low-speed bearings.

The difference in types between high-speed bearings and low-speed bearings:

Low speed bearings generally use rolling bearings, while high-speed bearings usually use sliding bearings, which are responsible for rotating parts inside the bearing. Low speed bearings use circular, cylindrical, and even conical rotors; And high-speed bearings use bearing shells, please pay attention to: Rongji igniter.

The difference between high-speed bearings and low-speed bearings can be seen from their appearance:

From the appearance, it can be found that the surface of high-speed bearings appears smoother, without roughness or some pits like low-speed bearings. The distance between the outer and inner rings is very small, and the accuracy of the bearings is also relatively high; At low speeds, the surface is relatively rough and the accuracy is also lower.

The materials used for high-speed bearings and low-speed bearings are different:

There are also some differences in materials. High speed steel uses metallographic and high hardness steel, which can withstand relatively large pressures; If the speed of ordinary bearings is relatively low, they use some ordinary materials and do not need to bear too much pressure, so the requirements for material hardness and durability are relatively reduced.

Both low-speed and high-speed bearings are actually manufactured after precise design by designers and repeated testing. Although its components are very small, its technological innovation and changes can often drive the development of an industry, and its role cannot be underestimated. Therefore, if the equipment we use in our daily life includes bearings, we must be careful not to damage them, otherwise it may require a large amount of maintenance costs.
