Generally speaking, the rolling mill stands will have 2 rolls, 3 rolls, 4 rolls, or a set of multiple rolls mounted onto the stands.  The loads on the rolls will transfer to the roll neck bearings and their housings during the rolling of steels. The roll neck bearings are to meet the basic need of the smooth rolling of steel products. They will differ from sizes, carrying capacities and other aspects, due to different requirements and working conditions. Therefore, they will have different configurations and speeds of rolling.

The bearings are designed to withstand high loads, impacts, varying speeds and high temperature. They also need to work with metal particles, dirt, and water. Therefore, the bearings should be made with good material and technique to endure the toughest working conditions. Roll neck bearings with high quality will help steel mills reduce a lot for reducing power consumption, downtime, and improving rolling conditions.

With best bearing material choosing, and strict control on processing, ESG Bearing is able to meet most modern steel mills’ high requirements. ESG Bearing is also the only 1 factory bearing manufacturers having 100% flaw detection on the bearings. Thus the bearing quality will be assured.

Steel metal rolling operations usually deform the materials by compressive forces between two constantly spinning rolls. These forces act to reduce the thickness of the metal and change its grain structure. Besides, the rolls will also feed the material when they are spinning to each other.

However, the rolls cannot function in isolation. During the rolling process, rolls, stands, bearings, housings, and motors are necessary parts for the operation. Usually, bearings will transmit motion and forces. They are usually mounted on the rolls and inserted into the housings. This is why the bearings on the mill stands are called roll neck bearings. These bearings should be strong enough to face with extreme temperatures, dust, contaminants, and variable humidity. They will also work under physical stresses of continuous high speed, extreme torque and shock loads.

Rolling bearings are mainly composed of high carbon chromium bearing steel.High-carbon chromium bearing steel is also called fully hardenable steel with the same inside and outside hardness. It is widely used in many industries with bigger quantity, over 80% of the total material.

1.GCr15

Feature and application：It can be applied in many industries with big quantity in Martensite and bainite quenching.

Technical specification：Effective wall thickness under 26mm，extra light and narrow series less than 16mm，Quenching and tempering hardness HRC57~62.

2.GCr15SiMn

Feature and application：it can be applied in many industrial with big-size bearings in Martensite quenching.

Technical specification：effective wall thickness thicker than 26mm，extra light and narrow series more than 16mm，quenching and tempering hardness HRC57~62.

3.GCr18Mo

Feature and application：bainite steel, used in wear resistant occasion with bainite quenching.

Technical specification：effective wall thickness within 26~48mm, extra light and narrow series less than 16mm, quenching and tempering hardness HRC57~62,bainite is more wear than martensite, better for wear resistant occasion.

Carburized bearing steel is also called semi-hardenable steel, which is soft inside and hard outside. The material has a certain degree of "elasticity" for impact resistance. It needs to be carburized and quenched, and the process is more complicated.

G20Cr2Ni4A

Features and uses: used in impact-resistant occasions, medium and large bearings, and can be deeply carburized.

Technical characteristics: The effective carburizing layer can be deeper than 2.5mm, and the surface quenching and tempering hardness is HRC58~63.

Bearing parts made of this type of steel have high hardness (hardness ≥ HRC58), certain wear resistance and high contact fatigue resistance after heat treatment processes such as carburization, quenching and tempering, and guarantee The heart has good toughness (hardness HRC33-48). This surface hardened core has the characteristics of toughness, making the carburized bearing steel particularly suitable for stable operation under conditions of large impact loads.

After carburizing and quenching, the surface retains the state of compressive stress and has good fatigue resistance. It has strong ability to bear impact load, and the surface hardened layer has micro cracks and it is not easy to expand to the inside. The surface has a higher hardness and the core hardness is lower. Compared with high carbon chromium bearing steel, it has better core impact toughness. The depth and concentration of carburization can be adjusted as required.

However, the cost of bearings made of G20CrNi4A is relatively high, and in the use of small and medium-sized bearings, their life will not be greatly improved compared with bearing steel. Therefore, only carburized steel is used for medium and large bearings.
