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.

Q1: Why buy Materials & Equipment from

A1: All products offered are carefully selected from China's most reliable manufacturing enterprises. Through its ISO certifications, adheres to the highest standards and a commitment to supply chain safety and customer satisfaction.


Q4: What makes stainless steel stainless?

A4: 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.

Q5: Can stainless steel rust?

A5: 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.

Special steel is specifically designed to perform well in high-temperature corrosion environments. It possesses unique properties that make it highly resistant to oxidation and corrosive reactions at elevated temperatures. One of the key factors that contribute to special steel's performance in high-temperature corrosion is its high chromium content. Chromium forms a protective oxide layer on the surface of the steel, known as a passive film, which acts as a barrier against corrosive elements. This passive film is stable even at high temperatures, preventing the steel from undergoing oxidation and corrosion. Additionally, special steel often contains other alloying elements such as nickel, molybdenum, and titanium, which further enhance its resistance to high-temperature corrosion. These elements increase the steel's ability to withstand aggressive chemical environments, such as those encountered in industrial processes involving high temperatures and corrosive substances. Furthermore, special steel is known for its excellent mechanical properties, including high strength and toughness, which enable it to withstand the harsh conditions of high-temperature corrosion. It can maintain its structural integrity and dimensional stability even when exposed to extreme temperatures and corrosive chemicals. Overall, special steel's superior resistance to high-temperature corrosion makes it an ideal choice for various applications in industries such as petrochemical, power generation, and aerospace. Its ability to maintain its performance and durability in challenging environments ensures the longevity and reliability of equipment and structures, ultimately reducing maintenance and replacement costs.
The specific requirements for special steel used in the railway wheel industry include high strength and toughness, excellent wear resistance, good heat resistance, and the ability to withstand heavy loads and impact. The steel must also have low levels of impurities to ensure its durability and longevity in the demanding railway environment. Additionally, it should possess good fatigue resistance to withstand repeated stress cycles and meet specific dimensional and mechanical property standards set by the industry.
Yes, special steel can be used in the production of surgical implants. Special steels such as stainless steel or titanium alloys are often chosen for their corrosion resistance, biocompatibility, and mechanical properties, making them suitable for manufacturing surgical implants that need to be durable and compatible with the human body.
There are several non-destructive testing methods that can be used to evaluate special steel materials. These methods are designed to detect any flaws or defects in the steel without causing any damage to the material itself. Some of the commonly used non-destructive testing methods for special steel include: 1. Ultrasonic Testing (UT): This method uses high-frequency sound waves to detect internal flaws or defects in the steel. Ultrasonic waves are directed into the material, and the reflected waves are analyzed to identify any discontinuities such as cracks, voids, or inclusions. 2. Magnetic Particle Testing (MT): This technique is primarily used to identify surface defects in steel. A magnetic field is applied to the material, and iron particles are applied to the surface. If there is a defect present, the magnetic field will cause the particles to cluster around the defect, making it visible for inspection. 3. Liquid Penetrant Testing (PT): PT is a widely used method to detect surface defects in special steel. A liquid dye is applied to the steel surface, and after a certain amount of time, excess dye is removed. A developer is then applied, which draws the dye out of any defects, making them visible for inspection. 4. Radiographic Testing (RT): This method involves the use of X-rays or gamma rays to examine the internal structure of special steel. The steel is exposed to radiation, and the resulting image is captured on a radiographic film or digital detector. This method is particularly effective in detecting internal defects such as porosity, inclusions, or cracks. 5. Eddy Current Testing (ECT): ECT is primarily used for surface inspection of special steel. It involves passing an electrical current through a coil that generates a magnetic field. Any variations in the magnetic field caused by defects on the surface of the steel can be detected and analyzed. These non-destructive testing methods provide valuable information about the quality and integrity of special steel materials without causing any damage. By employing these techniques, manufacturers and engineers can ensure that the steel meets the required standards and specifications, thus enhancing safety and reliability in various applications.
Yes, special steel can be used in the wastewater treatment industry. Special steel, such as stainless steel or corrosion-resistant alloys, is often utilized in the construction of equipment and infrastructure used in wastewater treatment plants. These materials offer high resistance to corrosion, chemicals, and harsh operating conditions, ensuring durability and longevity in wastewater treatment processes. Additionally, special steel's hygienic properties make it suitable for applications where cleanliness and sterilization are crucial.
