As the world's largest automotive industry chain exhibition, the 2024 Frankfurt Shanghai Auto Parts Exhibition grandly opened at the China National Exhibition Center today (December 2). The exhibition gathers rich resources from the global automotive industry chain, providing an efficient service platform for information exchange, industry promotion, and business services for participants at home and abroad.The 2024 Frankfurt Shanghai Auto Parts Exhibition covers an area of 350000 square meters and gathers more than 6700 exhibiting companies from around the world.

The 20th anniversary celebration of the 2024 Shanghai International Auto Parts, Maintenance, Testing, Diagnostic Equipment and Service Supplies Exhibition (Automechanika Shanghai) was successfully held from December 2 to 5, 2024 at the National Convention and Exhibition Center (Shanghai). The number of participating companies and visitors at this exhibition has broken previous records, fully demonstrating the important influence of Automechanika Shanghai as a professional service platform in the industry, and also reflecting the thriving development of the automotive industry.

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.

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.

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.

Manufacturers of different brands of bearings may have their own strengths and expertise in different types of bearings. Here are some well-known imported bearing brands and their preferred bearing types:SKF (Sweden): SKF is a leading global bearing manufacturer, with products covering various types of bearings.

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.

Process flow of bearing outer ring processing: Bearing steel ->Forging ->Annealing ->Turning ->Heat treatment ->Grinding ->Assembly ->Inspection ->Packaging and warehousingThe purpose of forging technology1. Forming: Control reasonable turning allowance.2. Obtain a high lifespan forging streamline distribution to ensure bearing life.3. Obtain the ideal metallographic structure and prepare for annealing and quenching.The purpose of annealing process1. Reduce hardness and prepare for machining.2. Obtain the ideal metallographic structure and prepare for quenching.3.

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.

（1） Linear bearing cages can be divided into stamped and solid types:a. Stamping cage: commonly made of steel plate, sometimes also made of copper plate. The advantage of this type of cage over metal solid cages is its lighter weight. The stamping cage occupies a small gap between the inner and outer rings of the linear bearing, making it easy for lubricating oil to enter the linear bearing and remain in the cage. According to the code principle, the stamping cage is only written into the code when it is not used as a standard structure.b.
