The application of Spherical roller bearings on mining machinery

Dec 13, 2023

        Spherical roller bearing structures are designed with two rows of rollers; a common spherical raceway is present in the outer ring, with two inner ring raceways angled around the bearing axis. This type of bearing has a self-aligning capability, which makes it less susceptible to errors caused by the angle of the shaft or, the bearing box seat or shaft bending. It is ideal for situations where installation errors or shaft deflection may cause angular errors. Spherical roller bearings can bear radial and axial loads acting in both directions.

1. Application of spherical roller bearings in mining machinery

        In mining machinery, spherical roller bearings are widely used in various equipment, such as crushers, coal mills, ball mills, excavators, etc. These equipment are often required to withstand high loads, rotational speeds and high temperatures, so they require high performance and stability bearings. The structural features of spherical roller bearings make them ideal for these devices.

Crusher

        The crusher is one of the most commonly used equipment in mining machinery, used to break ore into small pieces. Crushers often use Spherical roller bearings to support the central and drive shafts. Due to the ore's high hardness, the crusher must withstand high-impact loads, so it is necessary to use bearings with high load-bearing capacity and impact resistance. The structural characteristics of spherical roller bearings enable them to meet these requirements while having self-aligning properties and adapting to shaft deflection and angular errors.

Coal grinding machine

        The coal mill is a device used to grind coal into powder. In coal mills, spherical roller bearings are often used to support primary and drive shafts while withstanding high and shock loads. Due to the high hardness of coal, the coal mill must withstand high-impact loads and high temperatures, so it is necessary to use bearings with high load-bearing capacity and high-temperature resistance. The structural characteristics of spherical roller bearings enable them to meet these requirements while having self-aligning properties and adapting to shaft deflection and angular errors.

Ball mill

        The ball mill is a device used to grind ore into fine powder. In ball mills, spherical roller bearings are often used to support the main shaft and drive shaft while withstanding high and shock loads. Due to the high hardness of the ore, the ball mill must withstand high-impact loads and high temperatures, so it is necessary to use bearings with high load-bearing capacity and high-temperature resistance. The structural characteristics of spherical roller bearings enable them to meet these requirements while having self-aligning properties and adapting to shaft deflection and angular errors.

Excavator

        Excavators are equipment used to excavate ore and soil. In excavators, spherical roller bearings are often used to support the stick and bucket's drive shafts while withstanding high and shock loads. Since excavators operate in harsh environments and must withstand high-impact loads and high temperatures, bearings with high load-bearing capacity and high-temperature resistance are required. The structural characteristics of spherical roller bearings enable them to meet these requirements while having self-aligning properties and adapting to shaft deflection and angular errors.

2. Advantages of spherical roller bearings

The application of spherical roller bearings in mining machinery has the following advantages:

High load-bearing capacity: Spherical roller bearings have high load-bearing capacity and can withstand high loads and impact loads.

Self-aligning performance: Spherical roller bearings have self-aligning performance and can adapt to shaft deflection and angular errors.

High-temperature resistance: Spherical roller bearings have high-temperature resistance and can maintain stable performance in high-temperature environments.

Long life: Spherical roller bearings have long service life characteristics and can operate stably for a long time.

Simple maintenance: Spherical roller bearings are simple to maintain; check the lubrication condition regularly and replace the grease.

        Applying spherical roller bearings in mining machinery has the advantages of high load-bearing capacity, self-aligning performance, high-temperature resistance, long life and simple maintenance. These advantages make spherical roller bearings an ideal choice in mining machinery, which can improve equipment performance and stability, reduce maintenance costs and increase equipment utilization. As technology advances, more fields can adopt its use, and the application prospects of spherical roller bearings in mining machinery will also broaden.
