Bearings are an indispensable part of many mechanical components, and their performance directly affects the performance of the machinery. Therefore, many people also pay attention to the performance of these bearings when purchasing 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, it is divided into two types: 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 misunderstand him, not because the speed of the bearing itself is different, but because there are differences in the internal structure of the bearing, and 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 can only rotate in the hundreds per minute. In addition to their names and their linear velocity, another difference is that the parts used for rotation in their structure 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 appearance 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 its 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 caused by excessive rotational speed on the parts. However, ordinary bearings with lower speeds use 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 and repeated testing by designers. Although its components themselves 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 daily includes bearings, we must be careful not to damage it, otherwise it may require a large amount of maintenance costs.
