Application of thin-walled bearings in rolling mill industry

Nov 09, 2023

The rolling mill is an essential equipment in the metal processing industry. It is used to pass the metal blank through a series of rolling processes to make its shape and size more in line with the requirements. In rolling mills, bearings are critical support and transmission components, and their performance and quality directly affect rolled products' quality and production efficiency. Thin-section bearings are increasingly used in rolling mills as a new bearing type.

Let's briefly introduce thin-walled bearings:

Thin-wall bearings are lightweight and compact. Compared with traditional solid rolling bearings, they can significantly reduce the weight of the rolling bearings and the space occupied by the rolling bearings. This feature enables the application of thin-walled bearings in rolling mills to have the following advantages:

Reduced energy consumption: Due to the lightweight of thin-walled bearings, the overall weight of the rolling mill can be reduced, thereby reducing the energy consumption of the rolling mill.

Improve rolling accuracy: Since thin-walled bearings take up little space, they can reduce the gap in the rolling mill transmission system and improve the accuracy and stability of the transmission so that the rolled products have higher precision and better quality.

Increase the stiffness of the rolling mill: The compact design of the thin-walled bearing increases the stiffness of the rolling mill, making the rolling mill more stable and less prone to deformation during the rolling process.

Reduce noise and vibration: Due to the design features of thin-walled bearings, noise and vibration during rolling mill operation can be reduced, thereby improving the working environment.

The picture above compares precision thin-section bearings manufactured by FV and traditional bearings.

Application of thin-walled bearings in rolling mills

Working principle: In rolling mills, thin-wall rolling bearings are mainly used in support and transmission systems. It supports the roll through the support journal and simultaneously transmits power to the registration through the transmission system, allowing the roll to rotate.

Application parts: The application parts of thin-section bearings in rolling mills mainly include roll bearing seats, adjusting bearing hubs, transmission shafts, and other factors. These parts must take enormous loads and high-speed rotational movements, so high-performance thin-wall bearings must ensure regular operation.

Maintenance: Their care is relatively simple because thin-walled bearings are lightweight and compact. In daily use, you need to keep the rolling bearings clean and lubricated, regularly check the wear of the rolling bearings, and replace them in time. In order for the transmission system to operate properly, it is necessary to perform regular maintenance and inspections.

The benefits of thin-walled bearings in rolling mills

Improve production efficiency: Applying thin section bearings in rolling mills can reduce energy consumption and increase rolling accuracy and stiffness, thereby improving production efficiency. These advantages can enable enterprises to reduce production costs and improve economic benefits.

Improve the working environment: Thin-wall bearings can reduce noise and vibration during the operation of the rolling mill, thereby improving the working environment and employee comfort.

Promote technological progress: The application of thin-wall bearings in rolling mills can promote technological progress in the metal processing industry. Its emergence has improved some shortcomings of traditional solid rolling bearings, improving product quality and production efficiency. In addition, the design and manufacturing of thin-walled bearings also require the support of advanced technology, which will promote technological progress in related fields.

Enhance market competitiveness: Applying thin-wall bearings in rolling mills can improve the company's product competitiveness. Because its advantages can improve product quality and production efficiency, it can make the products produced by enterprises more competitive and gain more market share.

In short, applying thin-wall bearings in rolling mills has significant advantages and benefits. Its emergence can improve product quality and production efficiency, reduce energy consumption, improve the working environment, and promote technological progress. Therefore, promoting and applying thin-wall bearings is essential for the metal processing industry.
