What is the difference between high and low speed bearing ?
Release time:2020-03-19 16:32 Clicks:
Bearings are the most important parts in modern industry, and their performance technology will directly affect the development of certain fields. In normal life, we will constantly contact the bearings, such as bearings that will be needed on cars, machinery and equipment, so that these things can get better operation. Because the bearing is used in different fields, its classification will be different. Do you know that bearings also have high speed and low speed, how to distinguish high speed bearings from low speed bearings? What is the basis for this? The following shares the basis and differences between high-speed bearings and low-speed bearings.


 
The basis for distinguishing high-speed bearings from low-speed bearings:
 
Due to the different ways of using, bearings can be divided into high-speed bearings and low-speed bearings, but even so, their distinction is not based on how many revolutions can be counted from a single turn, and some low-speed bearings it The speed can reach nearly tens of thousands of revolutions, but although some are called high-speed bearings, their speed is only a few hundred revolutions per minute. Then, the low speed is the low speed bearing.
 
The difference between high-speed bearings and low-speed bearings:
 
Low-speed bearings generally use rolling bearings, high-speed general sliding bearings, that is, the place responsible for rotation inside the bearing is different. The low-speed bearing uses a circular, cylindrical, or even conical rotor ; And high-speed bearings use bearing pads, please pay attention: Rongji igniter.
The difference between high-speed bearings and low-speed bearings can be seen from the appearance:
From the perspective of the appearance, it will be found that the surface of high-speed bearings will look smoother, and there will be no rough or potholes on the surface like low-speed bearings. The accuracy is also higher; at low speeds, the surface is relatively rough and the accuracy is lower.
 
High-speed bearings and low-speed bearings use different materials:
 
There are also some differences in materials. High-speed ones are made of some metallurgical materials. Steels with high hardness can withstand relatively large pressures; while ordinary ordinary bearings use ordinary ones if the speed is relatively low. The material does not need to bear too much pressure, so the requirements for the hardness and durability of the material are also relatively reduced.

Both low-speed and high-speed bearings are actually manufactured after precise design by the designer and repeated inspections. Although its parts are very small, its technological innovation and changes can often lead to the development of an industry, and its role cannot be underestimated. Therefore, if our daily use equipment contains a bearing part, we must be careful not to damage it, otherwise it may cost a lot of maintenance costs.
