Steel bearing

Certainly, in the complex world of bearing manufacturing where accuracy and stability are kingmakers; all cater to heed is given by knowing what a bearing steel really means. These material grades on its turn comprise the backbone of bearings to achieve high seizure resistance, rolling fatigue strength and optimal capability for functioning in different conditions. Given that it is one of the top bearing manufacturers, ZNL Bearings recognizes such a fundamental role played by pressing steels for manufacturing high quality bearings as required in different industries.

Understanding Bearing Steels

Bearing steels include various types of high carbon chromium bearing steel, engineering steel and stainless steel heat- resistant. These materials are specially selected on the basis of their ability to withstand different applications which may include load, speed requirements; temperature ranges, lubrication conditions and contamination or corrosive media. There are many different types of steel used in manufacturing bearings. Failing to choose the right type for its application will undermine service performance be it precision instrument bearing or using it as a heavy-duty component and could affect aerospace, industrial machinery.

Types of Bearing Steels

Two broad categories of bearing steels exist: by means of hardening and case hardening. The through-hardened steels ensure to have the identical amounts of carbon content all along every part perpendicular to this bearing’s cross section; therefore, it is possible for these properties after heat treatment being homogeneous. However, in case of hard squeezed steels the process involves surface treatment to attain a harder outer layer and corresponding softer core. The decision between these types is based on factors like application needs, production limiting elements and industry norms.

Grades that are Major and Their Usages

High-carbon chromium bearing steel: This grade is recognized for its high hardness and wear resistance which make it suitable in machining jobs that require direct quenching with superior results. It gets general use in ball bearings and other precision parts.

Case hardening bearing steel: Carburizing process to the body of it endow with harder surface but impart toughness at core. This grade is perfect for demanding applications under severe conditions.

Stainless hardening and high-temperature bearing steel: Created to withstand oxidizing environments and high temperatures, this material provides superior corrosion resistance and temperature tolerance. It is essential for bearings which have to work in very severe conditions.

Medium-carbon bearing steel: By employing induction hardening, this grade provides high localized brilliance where necessary but keeps general ductility. It is widely applied in applications which require localized wear resistance.
