Bearings are an indispensable part of many mechanical components, and the performance of bearings directly affects the performance of mechanical use. Therefore, many people also pay attention to the performance of bearings when choosing mechanical equipment. Among them, the high and low speed operation of bearings plays a decisive role in the use of bearings, and we will differentiate between high and low speed operation of bearings.

In terms of speed, there are two types of bearings: high-speed bearings and low-speed bearings, and these bearings occupy a very important position in our current industrial field, and even drive the development of an industry. The various electrical facilities in the cars we usually drive have bearings.

What is the difference between high-speed and low-speed bearings? Many friends may have misunderstandings about it. It's not that the speed of the bearing itself is different, but rather that there are differences in the internal structure of the bearing. Whether the bearing belongs to high-speed or low-speed is determined by its linear speed. Many low-speed bearings can reach speeds of tens of thousands per minute, while some high-speed bearings only rotate a few hundred times per minute. In addition to their names and their linear velocities, another difference is that the parts used for rotation in their structures are also different. Generally speaking, the rotating parts in low-speed bearings are circular, some are cylindrical or even conical, while the rotating parts in high-speed bearings are mainly the bearing shells.

At the same time, there are some differences in appearance between the two. Generally speaking, low-speed bearings have a rougher surface and looser joints between parts. High speed bearings, in order to ensure their accuracy and precision, generally have a very smooth surface. At the same time, the distance between the inner and outer rings is very small, and their accuracy is also much higher.

Another point is that there are slight differences between high-speed and low-speed bearings in terms of materials. High speed bearings generally use very high hardness steel, which can withstand the pressure brought by high rotational speeds on the parts. However, ordinary bearings, if the speed is relatively low, use some ordinary materials and do not need to bear too much pressure, So the requirements for material hardness and durability have also been 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.
