Differentiation Between High And Low Speed Operation Of Bearings

Bearings are an indispensable part of many mechanical parts. The performance of the bearings will directly affect the performance of the machinery. Therefore, many people will also pay attention to the performance of the bearings when purchasing mechanical equipment. Among them, the high and low speed operation of the bearings It plays a decisive role in the use of bearings.

They are divided into two types according to speed: 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. We usually drive cars in our homes. Various electrical facilities have bearings.

What is the difference between high-speed and low-speed bearings? The internal structure of the bearing is different. Whether the bearing is high speed or low speed is divided by its linear speed. Many low-speed bearings can rotate at tens of thousands per minute, while some high-speed bearings can only rotate at a few hundred per minute. In addition to their names being related to their linear speeds, another difference is that the rotating parts of their structures are also different. Generally speaking, the rotating parts of low-speed bearings are round, and some are cylindrical. The shape is even tapered, and the rotating part of the high-speed rotating bearing is mainly the bearing bush.

At the same time, there are some differences between the two in appearance. Generally speaking, the appearance of low-speed bearings is rougher, and the joints between parts are looser. In order to ensure the accuracy and precision of high-speed bearings, Its precision is generally very smooth on the surface. At the same time, the distance between the inner ring and the outer ring is very small, and its accuracy itself will be 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 excessively high speeds on parts, while ordinary bearings generally use very high-hardness steel. If the speed of the bearing is relatively low, it uses some ordinary materials and does not need to bear too much pressure, so the requirements for the hardness and durability of the material are relatively reduced.
