Collaborating With WEEYH
WEEYH maintains close cooperation with China's top bearing research institute to provide high-quality bearings to global dealers.
Its representative materials, such as GCr15 (Chinese standard), AISI 52100 (American standard), 100Cr6 (European standard), etc., have the following main characteristics:
The high carbon content (approximately 0.95%-1.1%) provides the necessary hardness and wear resistance, which is key for bearings to maintain shape and dimensional stability when subjected to heavy loads and high-speed operations.
High chromium content (approximately 1.3%-1.65%) not only enhances hardenability, but also improves the material's wear resistance and fatigue life.
After proper heat treatment (such as quenching and low-temperature tempering), bearing steel can obtain high hardness (HRC 58-64) and good toughness to meet the high performance requirements of bearings.
During the use of bearings, high carbon chromium bearing steel can maintain good dimensional stability, which is very important to ensure bearing accuracy.
Although the corrosion resistance of high-carbon chromium bearing steel is not as good as stainless steel or some special alloys, it is still sufficient in most standard applications.
Compared with high-end special alloy materials or ceramic materials, traditional bearing steel has better cost-effectiveness, making it a priority in a wide range of industrial applications.
In short, traditional high-carbon chromium bearing steel has become the material of choice for the bearing manufacturing industry due to its excellent comprehensive performance and economy.
However, the development and selection of more advanced materials for special application environments and performance requirements are also industry trends.
WEEYH benefits from a cooperation with China's top bearing research institute. In the bearing industry, with improvements in materials science and growing demand for specific applications, some new materials may outperform traditional materials in terms of specific properties. These materials include:
such as silicon nitride (Si3N4) and zirconium oxide (ZrO2). Ceramic bearings offer excellent wear resistance, corrosion resistance and stability at high temperatures, while also providing very low coefficients of friction and high speeds. For electrically insulated and non-magnetic applications, ceramic materials are the best choice comparing to other steels!
This steel improves strength and corrosion resistance by increasing the nitrogen content, while maintaining good toughness. High-nitrogen steel performs well in the aspects of corrosion resistance and fatigue life, especially in marine and chemical industry applications.
Such as Cronidur 30, M50, 52100, etc. The alloy steel provides excellent hardness, wear resistance and fatigue life through special alloy design and heat treatment processes. It usually used in high-end applications such as aerospace bearings.
In specific bearing applications, carbon fiber composites are considered bearing materials due to their lightweight, high strength and low thermal expansion coefficient. While they do not compete directly with metallic bearing materials, carbon fiber composites offer unique advantages in applications where weight savings and performance improvements are required.
Each material has its own specific advantages and the most suitable application scenarios. Selection of the most suitable material will based on lots of factors , including the load, speed, temperature, environmental conditions, and cost effectiveness etc to consider with.
Bearing specialists of WEEYH will provide you with the best material options for your OEM bearings based on your working conditions.
