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.
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.
(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.
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.
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 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.
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.
