Cementation Bearing Steel
Cementation bearing steel is a kind of high-quality bearing steel produced by strengthening method. It is used for the manufacturing of various types of bearings, bearing liners, and other automotive parts which are subject to high loads and high rolling speeds. Cementation bearing steel has a high chromium content and a low carbon content. This allows it to be extremely hard and heat resistant, making it ideal for high stress and rolling speeds.
Compared to traditional bearing steels, such as alloy steels, cementation bearing steel has much higher mechanical properties. This makes it more suitable for high-speed and high-load applications. Compared to conventional bearings made from steel, cementation bearing steel can reduce wear on the bearing and increase the life of the bearing. This is important when the bearing is used in applications which require a high degree of accuracy and good performance.
Cementation bearing steel is produced with a process called carburization, also known as carburizing or cementation. During this process, the steel is heated in a furnace with carbon monoxide gas or a carbon alloy containing calcium, carbon, and silicon. The temperature and time of the carburization process depend on the desired results.
Cementation bearing steel has several advantages over conventional bearing steel, such as:
1. High hardness and wear resistance due to its high carbon content, making it ideal for high-speed and high-load applications.
2. Excellent finishing quality, allowing for accurate and precise manufacturing.
3. Lightweight without sacrificing durability, making it suitable for a range of applications.
4. Improved shock and vibration resistance, increasing the life cycle of the bearing.
5. High heat-resistance, making it suitable for high-speed, high-temperature applications.
These advantages make cementation bearing steel a popular choice for many mechanical and automotive parts. It is especially suitable for applications requiring high-precision bearings, as its excellent finishing qualities provide accuracy and reliability. Cementation bearing steel is also used in a range of other industries, such as the paper industry, where it is used to construct bearings used in printing machines.
Cementation bearing steel has a range of properties which make it an excellent choice for the manufacturing of bearings and their parts. These properties include:
1. High strength and ductility, allowing it to absorb higher loads, making it suitable for a range of industrial and automotive applications.
2. High hardness and wear resistance, providing an increased life cycle for the bearing and increased efficiency.
3. Light weight without sacrificing durability, making it suitable for a range of applications.
4. Excellent dimensional accuracy and finishing surface, providing reliable performance and good repeatability.
5. High heat resistance, making it suitable for high-speed and high-temperature applications.
Cementation bearing steel is widely used in the automotive and industrial sectors for manufacturing parts which are subject to high loads and high rolling speeds. Its unique combination of properties make it an excellent choice for precision-made components, such as bearings and bearing liners. Cementation bearing steel is produced in line with GB/T3203-1982, ensuring excellent quality and performance.
