The development of bearings has been underway for thousands of years. With the development of time, there are a growing number of different types of bearings, which correspond to different use scenarios. For the modern light industry, bearings can be said to be the most important material. The appearance of bearings can help machinery to improve efficiency and reduce wear and tear, bearings can be said to be the product of technology.
Nowadays, whether to use ball bearing or not has attracted a lot of controversies. Many people think ball bearing is an essential part of contemporary industry because it has so many benefits. While some think the price of ball bearings is a little high. Actually, ball bearing has become a common thing in people’s lives, but there are some people who still have no understanding of its importance and functions.
With aerospace, nuclear and industrial, electronic computer, optical electromagnetic instruments, precision machinery and other high-tech rapid development, the contemporary science, and technology level of the world bearing industry into a comprehensive innovation of manufacturing technology. Bearing is a typical representative of mature manufacturing technology.
Hardness range and application of bearing steelThe hardness range of bearing steel is usually between Rockwell hardness HRC 62-64, and the specific hardness value depends on different steel grades and heat treatment processes. For example, the hardness range of GCr15 bearing steel is HRC 62-64 1. Th
