What material is bearing steelBearing steel is a steel used to manufacture balls, rollers, and bearing rings. Bearing steel has high and uniform hardness, wear resistance, and high elastic limit. Strict requirements are placed on the uniformity of chemical composition, content and distribution of non-metallic inclusions, and distribution of carbides in bearing steel, making it one of the most stringent steel grades in all steel production.

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. SKF launches new generation of ball bearing products: SKF, the world's leading bearing manufacturer, announces the launch of a new generation of ball bearing products. This new product has a longer service life and higher load carrying capacity while improving bearing performance and reliability. 2. NSK launched self-lubricating bearing technology: Japan's NSK recently launched an innovative self-lubricating bearing technology. This new technology can significantly reduce the friction and wear of bearings, improving the efficiency and service life of equipment. 3.

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.

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.

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. 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.

In recent years, ceramic bearings have been increasingly used in various fields, such as aviation, aerospace, navigation, petroleum, chemical, automotive, electronic equipment, metallurgy, power, textiles, pumps, medical equipment, scientific research, and national defense and military. The advantages of using ceramic bearings in new products are becoming increasingly apparent. The following is a specific understanding of the advantages of using ceramic bearing materials.The advantages of ceramic bearing materials mainly include the following:1.
