At the 2024 China Automotive Forum held on July 12th, SKF was awarded the "2024 China Automotive Industry Sustainable Development Practice Outstanding Award" by the China Association of Automobile Manufacturers.

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.

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.

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.

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.

The bearing ring raceway is the surface of the bearing workpiece, and its quality will directly affect the working performance and service life of the bearing. During use, we often find common quality problems on the surface of bearing rings. How do these quality problems arise? Based on years of experience, here are common quality problems and their causes on the surface of bearing rings.1.

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.

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
