Bearing steel is a steel used to manufacture balls, rollers, and bearing rings. Bearings bear great pressure and friction during operation, so it is required that the bearing steel has high and uniform hardness and wear resistance, as well as high elastic limit.

When designing and manufacturing rolling bearings, the selection of bearing materials is generally based on the following principles.1、 Select according to the working conditions of the bearings①. Working temperatureBearings working at room temperature are made of chromium bearing steel. Chromium bearing steel is also used for working temperatures above 150 ℃ and below 250 ℃, but it needs to undergo special heat treatment (requiring tempering at 200 ℃ or 300 ℃).②.

Bearings are a common mechanical component used to support and rotate shafts in machines. As an important component of SFC bearings, the cage plays a role in fixing the position and separating the rolling elements, while also bearing the load of the bearing. The following will introduce three types of cages for SFC bearings, their respective characteristics, and different application environments.Conventional steel plate holderThe conventional steel plate cage is the most common type of bearing cage, which is formed by stamping two or more steel plates.

1. Correct mounting: Correct mounting is the first step to protect the bearing. Make sure you select the proper bearing type, the right amount of lubricant, and the correct mounting method. Follow the manufacturer's guidelines and recommendations to ensure that the bearing is properly installed and not over-pressurized or over-loosened. 2. Keep them clean: Bearings should always be kept clean. Prevent dust, dirt, liquids or other contaminants from entering the bearing. Clean the bearings regularly and make sure the surrounding environment is clean to avoid any possible damage.3.

The metallurgical quality of bearing materials was once the main factor affecting the early failure of bearings. With the improvement of metallurgical technology (such as vacuum degassing of bearing steel), the quality of raw materials has been improved. The proportion of raw material quality factors in the failure analysis of overall eccentric bearings has significantly decreased, but it remains one of the main influencing factors of bearing failure.

1. High end and precisionWith the rapid development of manufacturing industry and the promotion of industrial upgrading, the market demand for high-end bearings will continue to increase. Enterprises need to increase investment in technological innovation and research and development, improve product quality and performance levels, in order to meet the market's demand for high-performance and high-quality bearing products.Precision manufacturing is one of the development directions of the bearing manufacturing industry.

In the field of materials science, bearing steel and high carbon steel are two widely used types of steel, each with unique performance advantages and specific application categories. This article aims to explore the core differences between the two and how to make reasonable choices based on actual needs.The subtle differences in performance and compositionThe primary difference lies in their performance. Bearing steel stands out due to its excellent hardness advantage, which is attributed to the high content of chromium element.

1. Overheating Overheating of the microstructure after quenching can be observed from the rough mouth of the SFC bearing parts. But to accurately determine the degree of overheating, it is necessary to observe the microstructure. If coarse needle like martensite appears in the quenched structure of GCr15 steel, it is a quenched overheated structure.

After the opening ceremony, Zhou Yu, Chairman of the China Bearing Industry Association, accompanied leaders and guests such as Tang Jun, Director of the General Machinery Department of the Equipment Department of the Ministry of Industry and Information Technology, and Song Zhiming, former Deputy Director of the Planning Department of the Ministry of Industry and Information Technology, to visit the exhibition and exchange ideas with major exhibitors. During the exhibition, the China Bearing Industry Association, the China Petroleum and Petrochemical Equipment Association Industry Associ
