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: Can stainless steel rust?
A2: Stainless does not "rust" as you think of regular steel rusting with a red oxide on the surface that flakes off. If you see red rust it is probably due to some iron particles that have contaminated the surface of the stainless steel and it is these iron particles that are rusting. Look at the source of the rusting and see if you can remove it from the surface.
- Q:How is bearing steel used in the manufacturing of bearings?
- Bearing steel is specifically designed for the manufacturing of bearings due to its high hardness, wear resistance, and excellent rolling contact fatigue strength.

- Q:What are the different methods of preventing galvanic corrosion in special steel?
- There are several methods of preventing galvanic corrosion in special steel. Some common approaches include using protective coatings or barriers such as paints, varnishes, or corrosion-resistant alloys. Another method is cathodic protection, where a sacrificial anode is connected to the steel to attract corrosion instead. Additionally, controlling the environment by reducing moisture or adding inhibitors can also help prevent galvanic corrosion in special steel.
- Q:What are the different methods of surface coating for special steel?
- For special steel, there exists a variety of surface coating methods that can be utilized based on the desired outcome and application. Some of the most frequently employed techniques are as follows: 1. Electroplating: By employing an electric current, a thin layer of metal can be deposited onto the surface of the steel. This process enhances the steel's corrosion resistance, wear resistance, and overall aesthetic appearance. 2. Hot-dip galvanizing: This method entails immersing the steel in molten zinc, resulting in the formation of a protective coating on the surface. Hot-dip galvanizing offers exceptional corrosion protection and can be utilized for both interior and exterior applications. 3. Powder coating: This technique involves the application of a dry powder onto the steel's surface, followed by heating and curing to create a durable and visually appealing coating. Powder coating provides excellent corrosion resistance, impact resistance, and allows for customization of colors. 4. Physical vapor deposition (PVD): PVD is a vacuum coating process where thin layers of metal are deposited onto the steel's surface. This method enhances the steel's hardness, wear resistance, and chemical resistance. It is commonly employed for decorative finishes and to improve the performance of cutting tools. 5. Chemical conversion coating: This method entails treating the steel surface with a chemical solution, which reacts with the surface to form a protective coating. Chemical conversion coatings provide corrosion resistance and can serve as a base for painting or other coatings. 6. Thermal spraying: Thermal spraying involves melting or heating a coating material and projecting it onto the steel surface using a spray gun. This technique can be utilized to apply a wide range of coatings, including metals, ceramics, and polymers. Thermal spraying improves the steel's wear resistance, corrosion resistance, and thermal insulation properties. These examples merely scratch the surface of the available surface coating methods for special steel. The choice of method relies on factors such as desired properties, application requirements, and budget. Consulting with experts in the field is crucial to determine the most suitable coating method for specific steel applications.
- Q:What are the different methods of hardening special steel?
- There are several different methods of hardening special steel, including heat treatment, quenching, tempering, and carburizing. Heat treatment involves heating the steel to a specific temperature and then cooling it rapidly to increase its hardness. Quenching involves rapidly cooling the heated steel in a liquid, such as oil or water, to achieve high hardness. Tempering is a process that follows quenching, where the steel is reheated to a lower temperature to reduce brittleness and increase toughness. Carburizing is a method where the steel is heated in a carbon-rich environment to increase its surface hardness by infusing carbon atoms into the outer layer. These methods can be used individually or in combination to achieve desired hardness levels in special steel.
- Q:How does special steel maintain its strength at different temperatures?
- Special steel maintains its strength at different temperatures due to its unique composition and heat treatment process. It is alloyed with elements like chromium, nickel, and molybdenum, which form stable compounds at high temperatures, preventing the steel from losing its strength. The heat treatment process involves carefully controlling the cooling rate, which further enhances the steel's microstructure and ensures its strength is retained even at extreme temperatures.
- Q:How does special steel contribute to the machinery manufacturing industry?
- Special steel plays a crucial role in the machinery manufacturing industry by providing high-quality and durable materials for the production of various machine components. This type of steel is specifically engineered to possess exceptional strength, toughness, and resistance to wear, corrosion, and high temperatures. In the machinery manufacturing industry, special steel is utilized in the production of critical components such as gears, shafts, bearings, and cutting tools.
