Heavy load roller bearings are a widely used rolling bearing, mainly used to support rotating shafts bearing axial and radial loads. Its main functions include:

1 Supporting the rotating shaft: Heavy load roller bearings can withstand axial and radial loads, so they can support the rotating shaft, allowing it to rotate freely within the bearing. This is crucial for the operation and lifespan of equipment such as electric motors

2. Reduce friction and wear: Heavy load roller bearings are usually lubricated with grease or oil, which can reduce friction and wear between the rotating shaft and the bearing, thereby extending the life of the bearing

3. Provide rotational accuracy: The tolerance requirements for heavy-duty roller bearings are high, so they can provide a certain degree of rotational accuracy. This is very important for equipment that requires high-precision rotation

4. Load bearing: Heavy load roller bearings can withstand large axial and radial loads, so they can be used for equipment that needs to withstand heavy loads

In summary, heavy-duty roller bearings play an important role in supporting rotating shafts, reducing friction and wear, providing rotational accuracy, and withstanding heavy loads. They are widely used in various rotating machinery and equipment, such as motors, machines, ships, automobiles, airplanes, and wind turbines
