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: How does special steel contribute to the manufacturing of medical implants?
- Special steel plays a crucial role in the manufacturing of medical implants due to its unique properties and characteristics. Medical implants require materials that are biocompatible, corrosion-resistant, and durable. Special steels, such as stainless steel, titanium alloys, and cobalt-chromium alloys, possess these desired qualities, making them ideal for medical implant production. Firstly, stainless steel is widely used in the manufacturing of medical implants due to its excellent corrosion resistance and high strength. It is often employed in applications like surgical instruments, orthopedic implants, and dental devices. Stainless steel implants can withstand the harsh physiological environment within the body, ensuring long-term performance and reducing the risk of complications. Titanium alloys are another type of special steel extensively used in medical implant manufacturing. These alloys offer high strength-to-weight ratio, exceptional biocompatibility, and resistance to corrosion. Titanium implants are commonly used in orthopedic surgeries, such as joint replacements, as well as dental implants. The biocompatible nature of titanium allows for better integration with the surrounding bone, promoting faster healing and reducing the risk of rejection. Cobalt-chromium alloys are yet another type of special steel utilized in the production of medical implants. These alloys possess excellent mechanical strength, wear resistance, and biocompatibility. Cobalt-chromium implants are frequently employed in orthopedic surgeries and cardiovascular interventions, such as stents. Their high strength ensures stability and longevity, while their biocompatibility minimizes adverse reactions and promotes patient recovery. Overall, special steel provides the necessary qualities required for manufacturing medical implants. Whether it is stainless steel, titanium alloys, or cobalt-chromium alloys, these materials contribute to the development of biocompatible, corrosion-resistant, and durable implants that improve patients' quality of life and ensure successful medical procedures.
- Q: What are the main applications of special steel in the mining exploration?
- Special steel has various applications in mining exploration, primarily due to its exceptional strength, durability, and resistance to corrosion. It is commonly used in the construction of drilling equipment, such as drill bits and drill rods, which require high toughness and wear resistance to withstand the harsh conditions encountered during mining operations.

- Q: What are the properties of corrosion-resistant stainless steel?
- Corrosion-resistant stainless steel has several key properties. Firstly, it has a high level of chromium content, typically around 10-20%, which forms a protective oxide layer on the surface of the steel. This oxide layer acts as a barrier, preventing oxygen and moisture from reaching the underlying metal and causing corrosion. Additionally, stainless steel contains other alloying elements such as nickel, molybdenum, and nitrogen, which further enhance its corrosion resistance. These alloys help to stabilize the oxide layer and make it more resistant to corrosion by aggressive substances such as acids, salts, and chlorides. Furthermore, stainless steel is highly durable and has excellent strength, making it suitable for various applications in corrosive environments, including marine, chemical, and food processing industries.
- Q: How does special steel perform in welding applications?
- Special steel, also known as alloy steel, performs exceptionally well in welding applications. Its unique composition, which includes various alloying elements such as manganese, chromium, and nickel, enhances its weldability and overall performance. The addition of these alloying elements significantly improves the strength, hardness, and corrosion resistance of the steel, making it highly suitable for welding applications. Special steel possesses excellent weldability, allowing for easy fusion and formation of strong and durable weld joints. Furthermore, the alloying elements in special steel also contribute to its heat resistance, making it capable of withstanding high temperatures during the welding process without losing its structural integrity. This property is particularly crucial in applications where welding involves high heat levels or prolonged exposure to extreme temperatures. Moreover, special steel exhibits good ductility and toughness, enabling it to withstand the stresses and strains associated with welding. It can effectively absorb and disperse heat during the welding process, minimizing the risk of distortion or cracking in the welded joints. In addition to its mechanical properties, special steel also offers excellent resistance to corrosion and oxidation.
