Usage and Applications of Bearing Steel Round Bar
Bearing steels are used for ball and roller bearing applications and are comprised of low carbon steels and high carbon through harden able steel.
First the famous 1C-1.5Cr steel from which the majority of bearings are made. Its structure is apparently well-understood and the focus is on purity in order to avoid inclusions which initiate fatigue during rolling contact. Then there is the M50 steel and its variants, from which bearings which serve at slightly higher temperatures in aeroengines are manufactured, based on secondary-hardened martensite.
Tapered roller bearing are generally used to support combined load mainly consisting of radial load. Their cups are separable for easy assembling ,During mounting and using, radial clearance and axial clearance can be adjusted and preloaded mounting can be made.

FAQ：
Q1: How soon can we receive the product after purchase?
A1: Within three days of placing an order, we will begin production. The specific shipping date is dependent upon international and government factors, but is typically 7 to 10 workdays.
Q2: What makes stainless steel stainless?
A2: Stainless steel must contain at least 10.5 % chromium. It is this element that reacts with the oxygen in the air to form a complex chrome-oxide surface layer that is invisible but strong enough to prevent further oxygen from "staining" (rusting) the surface. Higher levels of chromium and the addition of other alloying elements such as nickel and molybdenum enhance this surface layer and improve the corrosion resistance of the stainless material.
- Q: What are the different forming processes for special steel?
- There are several forming processes for special steel, including hot forming, cold forming, and powder metallurgy. Hot forming involves heating the steel to a high temperature and then shaping it through processes like forging or rolling. Cold forming, on the other hand, involves shaping the steel at room temperature using processes like bending or extrusion. Powder metallurgy involves compacting metal powders and then sintering them to create a solid piece. These forming processes allow for the production of special steel with unique properties and shapes to meet various industrial needs.
- Q: How is special steel tested for quality and durability?
- Special steel is tested for quality and durability through a series of rigorous tests and inspections. These tests typically include measuring mechanical properties such as tensile strength, hardness, and impact resistance. Additionally, non-destructive testing methods like ultrasonic and magnetic particle inspections are used to detect any internal defects or inconsistencies. Quality and durability are ensured by adhering to strict industry standards and specifications, and only steel that meets the required criteria is deemed suitable for use.
- Q: What is the life cycle of special steel products?
- The life cycle of special steel products typically involves several stages, including raw material extraction, steel production, manufacturing of specialized products, distribution, usage, and eventual disposal or recycling. This cycle starts with the extraction of iron ore and other raw materials, which are then processed and transformed into steel through various methods such as smelting and casting. Once the steel is produced, it is shaped and formed into specialized products through forging, rolling, or machining processes. These products are then distributed to various industries, where they are used for applications such as construction, automotive, aerospace, and energy. Throughout their usage, special steel products may undergo maintenance, repairs, or modifications. Eventually, when they reach the end of their life, these products can be recycled or disposed of in an environmentally responsible manner to minimize waste and resource consumption.
- Q: What are the applications of special steel in the railway industry?
- Special steel has various applications in the railway industry, primarily due to its exceptional strength, durability, and resistance to extreme conditions. It is commonly used in the manufacturing of railway tracks, ensuring their longevity and ability to withstand heavy loads and frequent train traffic. Special steel is also employed in the production of railway wheels and axles, providing enhanced wear resistance and improved performance. Additionally, it is utilized in the construction of railway bridges and tunnels, where its high tensile strength and corrosion resistance are crucial for maintaining structural integrity and safety.
- Q: What is the role of carbon in special steel?
- Special steel relies on carbon to significantly impact its properties and performance. This type of steel is specifically engineered to showcase exceptional characteristics like high strength, hardness, wear resistance, and corrosion resistance. Carbon is a key alloying element in special steel, and its content dictates many of these desired properties. To begin, carbon is responsible for enhancing the strength and hardness of special steel. When carbon is introduced into the iron matrix, it forms iron carbides, which are exceptionally hard and provide structural integrity to the steel. The higher the carbon content, the greater the steel's hardness and strength. Consequently, special steel is well-suited for applications that demand high toughness, durability, and resistance to deformation, such as the manufacturing of tools, dies, and industrial machinery components. Additionally, carbon contributes to the wear resistance of special steel. The presence of carbon enhances the steel's ability to withstand abrasion and endure extreme conditions. This is especially important in industries like mining, construction, and oil and gas, where components face intense wear and friction. Moreover, carbon plays a crucial role in determining the machinability and weldability of special steel. The carbon content influences how the steel responds to heat treatment, affecting its ease or difficulty of machining and welding. Striking the right balance of carbon content is essential to ensure that special steel can be easily worked on and fabricated into complex shapes without compromising its properties. Lastly, carbon influences the corrosion resistance of special steel. Although steel is generally susceptible to corrosion, the addition of specific amounts of carbon can enhance its resistance to rusting and other forms of corrosion. This is particularly important in applications where the steel is exposed to harsh environments, such as in the marine or chemical industries. In conclusion, carbon plays a vital role in special steel by enhancing its strength, hardness, wear resistance, machinability, weldability, and corrosion resistance. The precise amount of carbon added to the steel is carefully controlled to achieve the desired properties for specific applications. This versatility and sought-after nature make special steel a highly valued material across various industries.
