ESG Bearing is an expert of rolling mill bearings. The working conditions for steel mill bearings are demanding as they will face dust, steel particles, water, heat, high speed and high temperature, almost the toughest conditions compared to other industry.

Bearing with higher hardness will be more wear-resistant, but it will easily crack. Thus the bearing's working life will be reduced.

How to  avoid this problem, most bearing manufacturers do not dare to make the bearings too hard. Their hardness is around 58~60 HRC. ESG Bearing has the advanced heat treatment technology. The tenacity of the bearing is improved by 30% compared with ordinary bearings. The hardness of the bearing is also improved by 2 HRC, reaching about 60~61 HRC. Thus the bearing is more wear-resistant and won’t easily crack out, it has a much longer working life.

Rolling mill bearings have to carry higher load and speed. They need to be more resistant to weariness and impact. Material takes an important role of the bearing performance. ESG Bearing selects the best mold casting steel, which contains less gas and particles, with the following features to improve the ESG bearing performance.

Better Grain Structure:Mold casting often results in a finer grain structure in the steel, which can contribute to improved mechanical properties such as strength, toughness, and wear resistance.

Higher Precision: Mold casting can provide higher precision in achieving intricate bearing designs and dimensions, especially for rolling mill applications.

Less Defects: Mold casting can lead to fewer internal defects like porosity and inclusions due to the controlled solidification process.

Better Surface Finish: Mold casting generally offers better surface finish and dimensional accuracy, which can be crucial for reducing friction and ensuring proper fitting in precision applications.

Four-row cylindrical roller bearings are essential components for steel rolling mills, as they must withstand heavy loads and operate reliably under harsh conditions. This unique design (four rows of rollers) ensures high load-carrying capacity and improved rigidity, making it an ideal choice for steel rolling mills.

Among the bearing models, bearing 313822 (280mm*390mm*220mm) is widely used in the steel mills.

One of the key benefits of the 313822 bearing for steel rolling mills is its ability to handle high speeds. Rolling mills operate at high speeds, and bearing 313822 is designed to handle high speeds without sacrificing performance or reliability. The lubrication system of the bearing will ensure proper lubrication of the rollers and raceways, even at high speeds.

Bearing 313822 is also featured with heavy carrying loads. Steel rolling mills require bearings that can handle heavy loads, while the four-row design of the bearing distributes the load evenly across all four rows of rollers, ensuring that the bearing can handle heavy loads without premature wear or failure.

In addition, four-row cylindrical roller bearing 313822 is highly durable and requires minimal maintenance. It is made from high-grade steel that has been heat-treated to improve its strength and durability. The rollers are precision-ground to ensure uniform contact with the raceways, reducing friction and wear. The bearing is also equipped with a sealing system that protects against contamination and moisture, further extending its lifespan.

Even though ESG Bearing has successfully made our rolling mill roller bearings with steel cage, brass cage is still popular among some clients. In order to make their preference and our persistence for a better performance meet, ESG Bearing has been searching and testing better brass material for our cage. And now we are proud that MISSION COMPLETE.

ESG Bearing is now able to offer our clients with a better performing brass cage, with higher antifriction and impact resistance.

The working conditions for steel mill bearings are demanding as they will face dust, steel particles, water, heat, high speed and high temperature.

Four-row cylindrical roller bearing works as the radial cylindrical roller bearings on the roll neck. Its performance values the most for the rolling mill bearings.

ESG Bearing, as an expert on steel rolling mill bearings. We are always improving ESG quality to better meet steel mill’s requirements. With years of testing, ESG Bearing now announced that ESG has successfully make our four-row cylindrical roller bearings with steel cage.

The working life, wear-resistance and performance of the radial cylindrical roller baring with steel cage proves to be better than bearing with brass cage.

Four row cylindrical roller bearings + Thrust Bearings

Cylindrical roller bearings inner diameter works together with roll neck to endure radial force. It has the advantages of heavy load, high rotation speed limit, high precision,inner and outer rings seperability and replacability, easy procession, lower production cost and convenient mounting and dismounting. The thrust bearings endure axial force. The detailed structure type can be chosen based on rolling mill feature.

When the heavy load speed is slow, the cylindrical roller bearings work with thrust bearings to endure thrust load with smaller axial clearance. When the rolling speed is higher, it works with angular contact ball bearings with higher rotation speed limit and with strick control of axial clearance to make the roller work with close axial guide and endure general axial load force.

This bearing specification type has the advantage of longer bearing life, reliability, high presion of the rolling products and easy control. So they are applicant widely in wire steel rolling mill, plate steel rolling mill,frame rolling mill, double-support roll of cold rolling mill and hot rolling mill.

Four Row Tapered Roller Bearings

Four row tapered roller bearings can endure both radial force and axial force without thrust bearings to make the main machine more compact. The inner diameter and the roll neck of four row tapered roller bearings work together with loose fit-up for convenient installation and dismounting. However sometimes the loose fit-up will slip. So the inner diameter will be made with screw oil tank.

At present, this specification model is still widerly applied in the working rolls of the four row hot rolling mill and cold rolling mill, bloomer and beam rolling mill.
