Application and features of spring roller bearings in steel plants

Oct 13, 2023

Spring roller bearings are widely used in steel plants. These bearings play an important role in the steel production process. The advantages of spring roller bearings include the following aspects:

Improve the rotation accuracy: When the crossed tapered roller bearing is preloaded, the internal clearance can be eliminated. Each rolling element bears a certain preload and supports the ring from all directions, which can improve the rotation accuracy and make the shaft in The axial and radial directions positioned correctly to enhance the rotation accuracy of the shaft.

Improve stiffness: The preloaded crossed tapered roller bearings are supported by springs in all directions and have a certain amount of preload. The number of rolling bearings under load is greater than when there is tension so that the stiffness can be improved.

Improve the life of the bearing: After the bearing is preloaded, the number of loaded rolling elements increases, and the load on each rolling element is reduced. At the same time, the load can be distributed evenly on each rolling element so the life of the bearing can be improved.

Improve bearing damping and reduce noise: Preload establishes a stable oil film between the rolling elements and raceways of crossed tapered roller bearings. By improving the damping between rolling elements and raceways, we can boost the structure's dynamic characteristics and lower noise levels.

Improve the dynamic performance of the bearing: In high-speed rotating bearings, appropriate preloading can prevent the steel ball from gyroscopic rotation, prevent or reduce the revolution and slippage of the steel ball, and control the spin sliding of the steel ball.

The application of spring roller bearings in steel plants will be introduced in detail below.

1. Continuous casting machine

In the continuous casting production line, the spring roller bearing is one of the key components. It directly contacts the steel billet and supports and clamps it. During the pouring process, spring roller bearings are also responsible for withstanding harsh conditions such as high temperature, high pressure, and high impact loads. They are an important guarantee for the normal operation of the continuous casting machine.

The CARB bearing used in continuous casting machines is a typical spring roller bearing. The internal structure of CARB bearings is a three-layer structure, including outer rings, cages, and rollers. The outer ring of the bearing, made of wear-resistant materials, is located on the outside. The cage is the middle structure of the bearing, which supports the rollers and maintains their correct position. The roller is the core part of the bearing. It generates friction with the journal or support to support and adjust the radial load.

CARB bearings can withstand bidirectional axial loads and can automatically adjust radial load imbalances. Therefore, they are suitable for bearing bidirectional axial and radial forces in continuous casting machines. In continuous casting machines, the stability and reliability of CARB bearings are crucial to the stability and safety of the continuous casting production line.

2. Rolling mill

In rolling mills, spring roller bearings also play a very important role. A rolling mill is an equipment used for plastic processing of metal materials. It can make metal blanks into products of various shapes through processes such as rolling, bending, and forging.

Spring roller bearings used in rolling mills mainly support and adjust radial loads. The rolling mill needs to bear huge radial loads during its operation, and spring roller bearings can automatically adjust the imbalance of radial loads to ensure the stable operation of the rolling mill. In addition, spring roller bearings have a long service life and low maintenance costs, which is one of the reasons why they are widely used in rolling mills.

3. Other applications

In addition to continuous casting and rolling mills, spring roller bearings have other uses in steel plants. For example, it is used to support and adjust rotating parts of various equipment, such as motors, generators, reducers, etc. In addition, spring roller bearings are also used in various auxiliary equipment, such as lubrication systems, hydraulic systems, conveying devices, etc., to play a supporting and adjusting role.

In short, spring roller bearings play an important role in steel plants, and their stability and reliability are crucial to the stability and safety of steel production lines. With the development of the steel industry and the continuous advancement of technology, the design and manufacturing technology of spring roller bearings has been continuously improved and perfected, providing important support for the optimization and upgrading of steel production lines.

Many models of FV's spring roller bearings are in stock and can be shipped within three days. For example, FV recently sent its stock spring roller bearings 65/108*70/58 to customers in Germany. At the same time, we also ordered non-standard spring roller bearings UL 90/150 x 76/64 for customers, with a delivery time of 35-40 days.
