Bearings for Continuous Caster

Introduction to the features of Spiral Roller Bearings

Spiral Roller Bearings, also known as spiral roller bearings, are high-performance, high-load-carrying bearings that are widely used in various heavy machinery and industrial fields, especially in high-demand production processes such as continuous casting and steel rolling.

The main structural feature of Spiral Roller Bearings is that the rollers are arranged in a spiral shape. This arrangement enables the bearings to withstand combined radial, axial, and angular loads. Compared with traditional cylindrical roller bearings, spiral roller bearings have a higher load-carrying capacity, mainly due to the special design and high-precision manufacturing of their rollers.

First, the spiral shape of the rollers allows each roller to spread out when it is loaded, thereby reducing the force on each roller and avoiding local overloading. At the same time, this shape also increases the length of the roller, thereby increasing its contact area with the bearing seat and further improving the load-bearing capacity.

Secondly, the manufacturing process of Spiral Roller Bearings requires extremely high precision and strict tolerance control to ensure their high standards of performance and quality. Its manufacturing process requires the application of advanced grinding and assembly technology to ensure that the shape and size of each roller are the same, thus ensuring the stability and long life of the bearing during operation.

In general, Spiral Roller Bearings play an irreplaceable role in heavy industries such as continuous casting and steel rolling due to their high load-bearing capacity, good stability, and long life. However, for such high-performance bearings, correct installation and maintenance are also very important. Therefore, users need to reasonably select and use Spiral Roller Bearings based on actual working conditions and usage requirements to ensure that they can fully function.

These special rolling bearing designs build the brand essence of the German "Eich." Initially, some of these bearing types had been used in various mining applications. An example is the yoke-type roller "Alaf," a type of wheel bearing for transport containers for discharging coal. The good experience in mining applications provided important insights into the performance of these bearings for other applications. One example is the steel industry with different applications: roller table rollers in rolling mills, support and guide rollers in continuous casting, and roller table rollers in furnaces or in finishing equipment.

What types of loads do spiral roller bearings mainly bear?

Spiral roller bearings mainly bear radial loads but can also bear combined radial and axial loads. The rolling system of this kind of bearing uses spiral rollers wound with steel belts, which have large elasticity and radial clearance and can withstand large-impact radial loads. In addition, they also have a lower limit speed and are suitable for parts with low rotation accuracy.

These rollers are arranged in a spiral pattern to increase load-carrying capacity. When the bearing is in operation, its rollers move both axially and radially, enabling it to withstand combined axial and radial loads. In addition, the special shape and high-precision manufacturing of these rollers allow them to spread the load and avoid local overloading, thereby increasing the life and stability of the bearing.

However, please note that spiral roller bearings cannot support axial loads. If you need to bear axial load, you should use thrust bearings or other bearing types that can withstand axial load.
