About Rolling mill bearings

Features of Rolling mill bearing

 1.High Load-Carrying Capacity

 Rolling mill bearings must be able to handle the huge pressure and impact force during the rolling process. With strong load-carrying capacity, they can bear the weight of rolls, rolling forces, as well as various static and static and dynamic loads to ensure the stable operation of the rolling mill. For example, four-row tapered roller bearings can carry relatively large combined radial and axial loads and are commonly used in large rolling mills; cylindrical roller bearings can enhance their impact resistance through optimized design.

 2.High Rotational Precision

The rotational precision of bearings is closely related to the dimensional accuracy and surface quality of rolled products. They need to operate precisely under high-speed rotation to ensure the positional accuracy of rolls and achieve stable dimensions of steel products. For instance, precision angular contact ball bearings can accurately control the radial and axial clearances to guarantee high-precision rolling. Moreover, they can reduce vibration and noise, improving the working efficiency of the rolling mill, enhancing product quality, and improving the working environment.

3. Good Wear Resistance and Corrosion Resistance

During operation, due to the friction between rollers and raceways, rolling mill bearings are prone to wear. Therefore, high-hardness, wear-resistant bearing steels such as GCr15 are often used, and special processes are combined to improve hardness and wear resistance to extend the service life. Meanwhile, in the working environment of rolling mill bearings, they may come into contact with corrosive media such as water, emulsion, and acid solution. Some bearings will select corrosion-resistant materials or undergo special protection treatments such as hard chromium plating.

4. Good Lubrication and Sealing Performance

Good lubrication is crucial for the normal operation of rolling mill bearings. Appropriate lubricants and lubrication methods can reduce friction, reduce wear, and dissipate heat to extend the service life. Grease lubrication or oil mist lubrication and other methods are commonly used, and parameters are selected according to working conditions. Reliable sealing devices are also needed. Seals like labyrinth seals and double lip seals can prevent external pollutants from entering and ensure a good working state.

5. High Temperature Resistance

During the rolling process, the temperature of the bearings will rise due to heat generated by friction and rolling forces. Therefore, rolling mill bearings need to be heat-resistant. High-temperature-resistant bearing steels and special lubricating materials are adopted to ensure normal operation under high-temperature conditions. Moreover, when the temperature changes, the size and performance of the bearings should remain stable. Through reasonable material selection and design, the reliability of the rolling mill under different temperature conditions is ensured.
