Bearing Introduction

China is one of the countries that invented rolling bearings earlier in the world. In Chinese ancient books, the structure of axle bearings has long been recorded. According to the archaeological relics and materials, the oldest bearing in China with the embryonic form of modern rolling bearing structure appeared in Xuejiaya Village, Yongji County, Shanxi Province, in 221~207 BC (Qin Dynasty).

Development of bearing industry

Bearing is an important basic part of all kinds of mechanical equipment. Its accuracy, performance, life and reliability play a decisive role in the accuracy, performance, life and reliability of the host. Among mechanical products, bearings are high-precision products, which not only need the comprehensive support of many disciplines such as mathematics and physics, but also need the services of many disciplines such as material science, heat treatment technology, precision machining and measurement technology, numerical control technology, effective numerical methods and powerful computer technology.

Performance Characteristics and Advantages of Deep Groove Ball Bearings

Deep groove ball bearing is the most representative rolling bearing, which is widely used. It is suitable for operation at high speed or even extremely high speed, and it is very durable without regular maintenance. This type of bearing has small friction coefficient, high limit speed, simple structure, low manufacturing cost and high manufacturing accuracy.

Purpose and method of bearing lubrication

The lubrication methods of bearings are divided into grease lubrication and oil lubrication. In order to give full play to the function of the bearing, first of all, it is necessary to select the lubrication method suitable for the use conditions and purposes. If only lubrication is considered, the lubricity of oil lubrication is dominant. However, grease lubrication has the advantage of simplifying the structure around the bearing, comparing the advantages and disadvantages of grease lubrication and oil lubrication.
