Application of Angular Contact Ball Bearings in Rolling Mills

Sep 21, 2023

Angular contact ball bearings have the characteristics of a small contact angle, large number of contact points, high load-bearing capacity, and small friction torque. Therefore, they suit high-load, high-speed machinery such as rolling mills.

In rolling mills, angular contact ball bearings are widely used in the rotating parts of various rolls and support rolls, providing important support and guarantee for the stable operation and precise control of the rolling mill.

Angular contact ball bearings are essential in rolling mills due to their superior performance and durability. Their application in rolling mills is especially critical, as they enable smoother operation and reduce wear and tear on the machinery.

Roll chock: The work rolls on the rolling mill need to rotate to complete the rolling of the metal material. Angular contact ball bearings support roll rotation and bear radial and axial loads. The precision and stability requirements of the rolling mill can be met by selecting the appropriate type and quantity of angular contact ball bearings.

Back-up roll chock: The back-up roll is an important part of the rolling mill. Its main function is to support the work roll and bear its weight. Angular contact ball bearings are also widely used in support roller bearing seats, ensuring the stable rotation of the support roller.

Adjustment devices: Angular contact ball bearings are also used in the adjustment devices of rolling mills. For example, when rolling metal materials, the position and angle of the roll need to be accurately adjusted to obtain the required plate shape and thickness. Angular contact ball bearings play a crucial role in this process, providing a basic guarantee for the precise movement of the adjustment device.

Lubrication system: Effective lubrication is essential to ensure that the bearings in the rolling mill can operate stably for a long time. Angular contact ball bearings have relatively high lubricant requirements due to their special structure and materials. Usually, the lubrication system accurately supplies lubricant to the bearings through special nozzles or lubrication grooves to ensure the normal rotation of the bearings.

Monitoring system: Modern rolling mills are typically equipped with various sensors and monitoring systems to provide real-time status updates on the mill's operation and the bearings' working conditions. Due to their high precision and stability, angular contact ball bearings can provide accurate data to the monitoring system, helping operators detect potential problems quickly and take appropriate measures.

In short, angular contact ball bearings are important in rolling mills. Their high speed, high precision, and high load capacity provide important guarantees for the stable operation of rolling mills.
